FXUS61 KLWX 270759 AFDLWX Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 359 AM EDT Fri Sep 27 2024 .SYNOPSIS... Hurricane Helene has made landfall along the northeastern Gulf Coast overnight, and is expected to quickly move into the southern Appalachians and Tennessee River Valley today into the weekend. Widespread rain is possible today, especially across parts of Central Virginia. Chances for rain will linger into early next week as an upper low remains overhead. && .NEAR TERM /THROUGH TONIGHT/... Hurricane Helene made landfall in the Big Bend of Florida this evening. This storm has a forward propagation speed of nearly 25 kts.. which is near the upper percentile for tropical cyclones. The upstream trough across the Lower Mississippi Valley is pulling the cyclone quickly northward. The center is already well into Georgia as of 03 AM with the outer rainbands making it into Virginia thanks to jet support/WAA. Through the day today, the remnants of Helene will continue to move northward, but get pulled west slightly towards the trough. Other than another day of cloudcover and highs in the 70s, Helene will bring several hazards to the area: - Heavy rain threat... Given the tropical airmass with PW values well above climo norms for late September (~1.5-2.2"), repeated rounds of moderate to heavy rain are expected today. The greatest coverage will be across a line from roughly Highland County, VA to Albemarle County, VA this morning. By this afternoon and into this evening, a broken line of showers/thunderstorms or several lines may develop, but coverage should be more scattered in nature. Given the SE`ly fetch off the Atlantic, abundant moisture is upsloping into the Blue Ridge and Alleghenies. The higher terrain of these locations have the greatest potential for Flash Flooding (especially where recent rains have exceeded 2-4"). Another 2-4" look possible across the higher terrain of the watch area through this evening. Have maintained the Flood Watch for these locales. Further north and east, less forcing exists and lesser amounts of rain are expected. - Strong Winds...The remnant wind field with Helene is extensive. As of 3 AM mesonets across the higher terrain of the Alleghenies and Blue Ridge are already gusting to 20-30 mph. As the remnants move north through the morning and afternoon, the winds will increase across the Blue Ridge and Alleghenies. A core of 40-60 kts of wind at H85 is forecast across central VA that pivots into the Ohio Valley. There is a good amount of disagreement between models on how far northeast these winds make it into the local forecast area, especially at lower elevations. Have expanded the Wind Advisory in coordination with PBZ to our common border. Bufkit profiles suggest 40-45 kts should mix down around 2500 ft, with 45-50 kts closer to 3500/4000 ft. There is a better signal for downsloping west of the Alleghenies, but northwestern Garrett County could downslope as well directly west of Keysers Ridge towards Friendsville. The saturated ground will likely allow for trees to fall as well. Across the lower elevations and metros, gusts to 20-30 kts are possible. - Severe Potential (including tornadoes)... By this afternoon, a broken line or broken lines of showers/thunderstorms are possible. The best overlap in instability/shear/SRH is across central VA. SPC has a Marginal Risk (Level 1 out of 5) that is tornado driven (2%). The further north into the forecast area, there is less instability. However, in tropical environments it does not take much instability. The one limiting factor is the forcing is definitely better closer to the center which is forecast to track well to the west. The region will reside in a tropical airmass tonight with lows only falling into the upper 60s in the metros with upper 50s west of the Blue Ridge. Dew points will be near the air temp, so fog formation appears rather likely. Rain chances look to be low overnight with PWs actually decreasing heading into Saturday.

Hurricane Helene Discussion Number 12 NWS National Hurricane Center Miami FL AL092024 400 AM CDT Thu Sep 26 2024 Helene is sending some mixed structural signals this morning. On one side, an Air Force Reserve Hurricane Hunter aircraft reports that the central pressure has fallen to near 966 mb, and satellite imagery shows the eye is trying to clear out. On another side, the aircraft reported concentric eyewalls of 16 and 32 n mi diameter, with the maximum flight-level winds, 80 kt at 700 mb, occurring about 50 n mi southeast of the center likely in relation to the outer eyewall. Based on the central pressure fall and the available data, the initial intensity is increased to 80 kt. The hurricane is starting its expected turn toward the north-northeast, with the initial motion now 015/10. The hurricane should accelerate north-northeastward during the next 24 h or so in the flow between a ridge over the Atlantic and a deep-layer baroclinic trough/cut-off low over the Tennessee Valley. This motion should bring the center of Helene to the coast of the Florida Big Bend region Thursday evening or early Friday morning. After landfall, Helene should turn northward and northwestward around the northeast and north side of the Tennessee Valley system. After 48 h, what is left of Helene should make a cyclonic loop as it merges with the baroclinic system. The latest track guidance has nudged a little to the northeast, especially near 36 h, and the portion of the new forecast track over Georgia and Tennessee has been moved a bit to the east. Helene remains in an atmospheric and oceanic environment over the eastern Gulf of Mexico that is very conducive for strengthening, with the system forecast to traverse the Loop Current while it remains in a moist and low-shear environment. The main restraining factor on intensification is the current concentric eyewall status. All of the intensity guidance continues to forecast strengthening until landfall. Based on this, the new intensity forecast calls for Helen to become a major hurricane in about 12 h, and additional intensification is expected in the ensuing 6 h period or so before landfall. After landfall, Helene should weaken and undergo extratropical transition as it merges with the baroclinic system over the Tennessee Valley, and this is expected to be complete by about 36 h. The remnant extratropical low is forecast to dissipate after 72 h based on global model forecasts. Helene is forecast to be a large major hurricane when it reaches the Big Bend coast of Florida. As a result, storm surge, wind, and rainfall impacts will extend well away from the center and outside the forecast cone, particularly on the east side. In addition, the fast forward speed when Helene moves inland will result in a far inland penetration of strong winds over parts of the southeastern United States, including strong gusts over higher terrain of the southern Appalachians. Indeed, the GFS and ECMWF models suggest the possibility that the inner wind core may persist until the center reaches northern Georgia. A higher-than-normal gust factor is indicated in the official forecast while Helene is inland. KEY MESSAGES: 1. A catastrophic and deadly storm surge is likely along portions of the Florida Big Bend coast, where inundation could reach as high as 20 feet above ground level, along with destructive waves. There is also a danger of life-threatening storm surge along the remainder of the west coast of the Florida Peninsula. Residents in those areas should follow advice given by local officials and evacuate if told to do so. 2. Potentially catastrophic hurricane-force winds are expected within the eyewall of Helene when it makes landfall in the Florida Big Bend region later today. Preparations to protect life and property should be completed this morning before tropical storm conditions arrive. Damaging and life-threatening hurricane-force winds, especially in gusts, will penetrate well inland over portions of northern Florida and southern Georgia later today and tonight where Hurricane Warnings are in effect. Strong wind gusts are also likely farther north across portions of northern Georgia and the Carolinas, particularly over the higher terrain of the southern Appalachians. 3. Catastrophic and life-threatening flash and urban flooding, including numerous significant landslides, is expected across portions of the southern Appalachians through Friday. Considerable to locally catastrophic flash and urban flooding is likely for northwestern and northern Florida and the Southeast through Friday. Widespread significant river flooding and isolated major river flooding are likely. 4. Tropical storm conditions are expected over portions of western Cuba within the Tropical Storm Warning area. Hurricane Helene will bring heavy rain to portions of the western Caribbean with potentially significant flooding across western Cuba and the northeastern Yucatan Peninsula through this morning.

For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Hurricane Helene was located near latitude 24.2 North, longitude 86.2 West. Helene is moving toward the north-northeast near 12 mph (19 km/h). This general motion is expected to continued with a significant increase in forward speed during the next 24 hours. On the forecast track, Helene will move across the eastern Gulf of Mexico today and cross the Florida Big Bend coast this evening or early Friday morning. After landfall, Helene is expected to turn northwestward and slow down over the Tennessee Valley on Friday and Saturday. Maximum sustained winds have increased to near 90 mph (150 km/h) with higher gusts. Strengthening is forecast, and Helene is expected to be a major hurricane when it reaches the Florida Big Bend coast this evening. Weakening is expected after landfall, but Helene's fast forward speed will allow strong, damaging winds, especially in gusts, to penetrate well inland across the southeastern United States, including over the higher terrain of the southern Appalachians. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 345 miles (555 km). The Key West Naval Air Station recently reported sustained winds of 41 mph (66 km/h) and a wind gust of 64 mph (103 km/h). The estimated minimum central pressure based on Air Force Reserve Hurricane Hunter aircraft data is 966 mb (28.53 inches). HAZARDS AFFECTING LAND ---------------------- Key Messages for Helene can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/text/MIATCDAT4.shtml STORM SURGE: The combination of a life-threatening storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Carrabelle, FL to Suwannee River, FL...15-20 ft Apalachicola, FL to Carrabelle, FL...10-15 ft Suwannee River, FL to Chassahowitzka, FL...10-15 ft Chassahowitzka, FL to Anclote River, FL...8-12 ft Indian Pass, FL to Apalachicola, FL...6-10 ft Anclote River, FL to Middle of Longboat Key, FL...5-8 ft Tampa Bay...5-8 ft Middle of Longboat Key, FL to Englewood, FL...4-7 ft East of Mexico Beach, FL to Indian Pass, FL...3-5 ft Englewood, FL to Flamingo, FL...3-5 ft Charlotte Harbor...3-5 ft For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at4.shtml?peakSurge. Storm surge could raise water levels by as much as 2 to 4 feet above normal tide levels in areas of onshore winds along the southern coast of Pinar del Rio, Cuba, including the Isle of Youth. WIND: Hurricane conditions are expected within the U.S. hurricane warning area late today, with tropical storm conditions beginning this morning. Tropical storm conditions are spreading across the Florida Keys at this time, and they are expected to spread northward across the rest of Florida, Georgia, and South Carolina through tonight. Tropical storm conditions are expected over portions of the warning area in western Cuba during the next few hours. RAINFALL: Hurricane Helene is expected to produce total rain accumulations of 4 to 8 inches over western Cuba, the Cayman Islands and the northeast Yucatan Peninsula, with isolated totals around 12 inches. This rainfall brings a risk of considerable flooding. Over portions of the Southeastern U.S. into the Southern Appalachians, Helene is expected to produce total rain accumulations of 6 to 12 inches with isolated totals around 18 inches. This rainfall will likely result in catastrophic and potentially life-threatening flash and urban flooding, along with significant river flooding. Numerous landslides are expected in steep terrain across the southern Appalachians. For a complete depiction of forecast rainfall associated with Hurricane Helene, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at4.shtml?ero. TORNADOES: The risk for several tornadoes will gradually increase today through tonight. The greatest threat is expected from parts of northern Florida into southeast Georgia, the Midlands and Low Country of South Carolina, and southern North Carolina. SURF: Swells generated by Helene will affect the southern coast of Cuba and the Yucatan Peninsula of Mexico during the next couple of days. Swells will spread northward toward the west coast of Florida and the northeastern Gulf Coast today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 700 AM CDT. Next complete advisory at 1000 AM CDT. $$ Forecaster Beven

Tropical Storm Isaac Discussion Number 1 NWS National Hurricane Center Miami FL AL102024 1100 PM AST Wed Sep 25 2024 The non-tropical area of low pressure we have been monitoring to the northeast of Bermuda over the last day or so has become significantly better organized today, with deep central convection forming and now wrapping around a small surface circulation. While the system had previously been attached to an occluded frontal boundary to its northwest, recently received scatterometer data now shows that the circulation has fully detached form this boundary, and is producing winds of 40-45 kt in a small circular area embedded within the organizing convection. These structural changes indicate the the system has undergone and has completed tropical transition. Thus, the system is now being designated Tropical Storm Isaac this advisory, and the initial intensity is set to 45 kt based on the earlier scatterometer data. Isaac is moving just north of due east at 85/10 kt. This motion should continue with a gentle turn more east-northeastward over the next several days as the system is steered primarily by mid-level ridging present to its south. However, there does not appear to be a mid-latitude trough early on to help the storm to accelerate much over the next few days. The initial NHC track forecast is in good agreement with the simple and corrected consensus aids TCVN and HCCA. While Isaac is traversing only marginally warm waters, it is also still embedded within the base of an upper-level trough which has reduced tropospheric stability due to colder upper-level temperatures. This is partially why Isaac has been able to develop organized deep convection this evening. The shear is not anticipated to increase much over the next couple of days, which could allow for some gradual intensification. The NHC intensity forecast is in good agreement the with HCCA and ECMWF forecasts and shows a peak intensity of 60 kt in 48 h, followed by gradual weakening after 72 h as sea-surface temperatures cool further and shear begins to increase more markedly.

Hurricane Helene Discussion Number 10 NWS National Hurricane Center Miami FL AL092024 400 PM CDT Wed Sep 25 2024 A ragged eye is becoming apparent in visible satellite imagery and has also been observed in recent radar data from Cancun and western Cuba. Based on the improved structure, the initial intensity is set at 75 kt, which is at the high end of the satellite intensity estimates. This is also supported by the earlier Air Force Reserve reconnaissance mission, which measured a peak 700-mb flight-level wind of 81 kt. Helene has turned northward (355/9 kt) and is expected to accelerate toward the north or north-northeast during the next 24-36 hours as it moves across the Gulf of Mexico and crosses the Florida Big Bend coast Thursday evening. After landfall, the system is forecast to interact with a deep-layer trough to the west and turn northwestward with a decrease in speed over the Tennessee Valley. The environment appears primed for significant strengthening while Helene moves across the Gulf of Mexico. The forecast track more or less runs along the axis of the Loop Current during the next 24 hours, where ocean temperatures are about 30 degrees Celsius. In addition, Helene will be moving through an environment of low vertical shear and strong upper-level divergence. Some of the Rapid Intensification (RI) indices, particular DTOPS, respond to this environment by indicating at least a 90 percent chance of a 35-kt increase in intensity over the next 24 hours. The NHC intensity forecast now shows an intensity of 115 kt (Category 4) at 24 hours, which is mirrored by several of the regional hurricane models and the SHIPS guidance. It should be noted that additional strengthening is possible beyond 24 hours before Helene makes landfall Thursday evening. Helene is forecast to be a large major hurricane when it reaches the Big Bend coast of Florida. As a result, storm surge, wind, and rainfall impacts will extend well away from the center and outside the forecast cone, particularly on the east side. In addition, the fast forward speed when Helene moves inland will result in a far inland penetration of strong winds over parts of the southeastern United States, including strong gusts over higher terrain of the southern Appalachians. A higher-than-normal gust factor has been indicated in the official forecast while Helene is inland. KEY MESSAGES: 1. A catastrophic and deadly storm surge is likely along portions of the Florida Big Bend coast, where inundation could reach as high as 20 feet above ground level, along with destructive waves. There is also a danger of life-threatening storm surge along the remainder of the west coast of the Florida Peninsula. Residents in those areas should follow advice given by local officials and evacuate if told to do so. 2. Potentially catastrophic hurricane-force winds are expected within the eyewall of Helene when it makes landfall in the Florida Big Bend region late Thursday. Preparations to protect life and property should be completed by early Thursday before tropical storm conditions arrive. Damaging and life-threatening hurricane-force winds, especially in gusts, will penetrate well inland over portions of northern Florida and southern Georgia late Thursday and Thursday night where Hurricane Warnings are in effect. Strong wind gusts are also likely farther north across portions of northern Georgia and the Carolinas, particularly over the higher terrain of the southern Appalachians. 3. Catastrophic and life-threatening flash and urban flooding, including landslides, is expected across portions of the southern Appalachians through Friday. Considerable to locally catastrophic flash and urban flooding is likely for northwestern and northern Florida and the Southeast through Friday. Widespread minor to moderate river flooding is likely, and isolated major river flooding is possible. 4. Hurricane and tropical storm conditions are expected over northeastern portions of the Yucatan Peninsula of Mexico this evening where Tropical Storm and Hurricane Warnings are in effect. Tropical storm conditions are occurring over portions of western Cuba within the Tropical Storm Warning area, and hurricane conditions are possible this evening within the Hurricane Watch area.

12z CMC sure is taking its sweet time in the W GOM from Day 5 on... finally makes landfall in W LA day 9

Last call for severe tomorrow? MRGL risk up west of the Blue Ridge from SPC for Day 2 Morning AFD from LWX SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... This is my seventh night shift, and I feel like this amplified upper level pattern has changed this weekend`s forecast a little bit each day. For Saturday, the low remains off the coast and high pressure remains to the north. However, now there appears to be a bit more defined low and frontal pattern that approaches from the Great Lakes combined with a shortwave in northwest flow aloft. The warm sector will feature highs in the lower to mid 80s and dew points in the lower to mid 60s. This will aid in developing some instability, so showers and thunderstorms should develop with the approaching forcing. Most models suggest decent coverage (40-60 percent) starting midday west of the Blue Ridge and then spreading east during the afternoon and evening. While instability will be somewhat modest, shear of 30-40 kt is forecast by some guidance. This could result in some organized storms that could produce hail and localized wind damage. Right now the greatest chance for severe weather appears to be west of I-95, where storms are most likely during peak heating (along with slightly higher instability). While storms should weaken some as they push east, there does appear to be enough forcing for showers and isolated storms to last well into the night.

Or the 18z GFS goofy solution of a strong TS into W FL near Tampa and then right up Eastern Seaboard into New England

At 993mb... so probably just a TS

Then rakes the SE coastline from JAX to HSE

12z CMC is into W LA. 12z GFS is only 500 miles NE of where it was at 06z at 225/228. Headed into W FL north of Tampa. Comes off E FL coast near JAX at 240. Stays far enough offshore, but SE coastline from FL to NC gets raked

DFA way too late https://www.mlbtraderumors.com/2024/09/orioles-designate-craig-kimbrel-for-assignment.html

True, but I think this is the first time we have seen this type of solution. I believe we are getting towards a "storm will be happening"... the question is strength and track.

Not sure I buy the 36 hour cutoff idea on the GFS as it sits off the GA/FL coast before finally deciding to skedaddle NE and out to sea
