Hurricane Ian Discussion Number 19 NWS National Hurricane Center Miami FL AL092022 500 PM EDT Tue Sep 27 2022 The pressure on the last Air Force Hurricane Hunter aircraft fix fell to about 952 mb, indicating that Ian is restrengthening over the southeastern Gulf of Mexico. The eye of Ian remains well-defined on visible imagery, although radar data from Key West suggest that an eyewall replacement could be in the initial stages. The initial wind speed is set to 105 kt, matching a blend of earlier SFMR and flight-level wind data. The plane data also showed that the area of hurricane-force winds is growing on the east side of the cyclone. Ian is moving east-of-due-north, or 010/9-kt, with occasional wobbles to the north-northeast. A track toward the north-northeast is expected for the next couple of days while it moves between a ridge over the Bahamas and a trough over the western Gulf of Mexico. There has been some model convergence this afternoon showing Ian remaining stronger and vertically deeper through landfall. This solution results in a faster track, again adjusted to the southeast, and the new forecast is moved in that direction. This new NHC track is close to the corrected model consensus and between the quicker ECMWF and slower GFS models. It should be emphasized that this track remains uncertain, with a typical spread in the steering features leading to big speed and track differences down the line, not to mention the oblique angle of approach to Florida. In a few days, more of the guidance is showing Ian interacting with a shortwave trough over the southeastern United States, causing the system to move back over the northwestern Atlantic in the longer range, before turning northwestward back over land. The day 3-5 track forecast is also shifted eastward, although significant re-strengthening is not expected at long range. The outflow pattern of the hurricane is beginning to be impinged upon in the southwestern quadrant, a sign that upper-level southwesterly flow is starting to affect the outer circulation. While the shear should increase up through landfall, it is just too close-to-call whether it starts to weaken Ian or not, or whether the larger system is able to resist the shear. Additionally, an eyewall replacement cycle could be in its initial phases, although predicting these structural changes is extremely difficult. The new forecast is near the last one, a little higher than the consensus. I should note that whether Ian comes ashore as category 4 hurricane or a large category 3 after an eyewall cycle, avoiding a large and destructive hurricane for Florida seems very unlikely, and residents should heed the advice of local emergency management officials. The new forecast necessitates a Hurricane Warning for portions of extreme southwestern Florida, and a Tropical Storm Warning for the rest of southeastern Florida that wasn't previously under a warning. Users are reminded to not focus on the exact track as some additional adjustments to the track are possible. Significant wind, storm surge, and rainfall hazards will extend far from the center. Key Messages: 1. Life-threatening storm surge is increasingly likely along the Florida west coast where a storm surge warning is in effect, with the highest risk from Naples to the Sarasota region. Residents in these areas should listen to advice given by local officials and follow any evacuation orders for your area. 2. Hurricane-force winds are expected in the hurricane warning area in southwest and west-central Florida beginning Wednesday morning with tropical storm conditions expected overnight. Devastating wind damage is expected near the core of Ian. Residents should rush all preparations to completion. 3. Heavy rainfall will affect most of the Florida Peninsula for the next several days, spreading to the rest of the Southeast U.S. by Thursday and Friday, likely causing flash, urban, and small stream flooding. Considerable flooding is expected with widespread, prolonged moderate to major river flooding expected across central Florida.

LWX AFD from this afternoon .LONG TERM /FRIDAY THROUGH MONDAY/... Dry and cooler than average once again on Friday as strong high pressure remains entrenched over the northeastern CONUS. Highs for most will remain in the 60s. Rain chances start to encroach on our region as early as Friday evening as the remnants of what is now Hurricane Ian approach from the south. For the weekend and even into Monday, a great deal of uncertainty remain regarding the track of Hurricane Ian. What does seem certain at this point is that our region should at least see some rainfall from Ian Saturday into Sunday. Whether that is a beneficial or hazardous amount has yet to be seen. We will continue to monitor the forecast for Ian and adjust the forecast as needed. For updates on Hurricane Ian, visit the National Hurricane Center website at hurricanes.gov.

1-3" across the LWX CWA per the 00z UKIE
-
00z GFS says rainy Monday for all but some rain Sunday south of the i66 corridor... 00z CMC rainy late Sat into Monday morning
-
Thats why I said FWIW
-
So did the 00z GFS... so...
-
FWIW, 00z CMC slows down, but remains offshore of the west coast of FL as it goes by, makes landfall in the Big Bend of FL
-
lol look at the 00z GFS at 126... decent CAD... 1034mb HP in Quebec...
-
Thats a long time Ian is hanging around Tampa with little movement on the 00z GFS... 30 hours
-
if you choose to accept the 00z ICON, that would be a rainy weekend with maybe a threat for a few isolated tornadoes
-
lol 00z ICON goes for a 2nd landfall at Savannah, GA at 102
-
day 5 NHC has Ian (as a TD) in S NC

Hurricane Ian Discussion Number 16 NWS National Hurricane Center Miami FL AL092022 1100 PM EDT Mon Sep 26 2022 Ian continues to become better organized on satellite images with intense deep convection in its Central Dense Overcast and numerous surrounding banding features. The overall cloud pattern is quite symmetric with well-defined upper-level outflow. Observations from both Air Force and NOAA Hurricane Hunter aircraft indicate that the central pressure is falling, and the intensity is increased to 90 kt based on a recently reported 700 mb flight-level wind of 101 kt from the Air Force plane. This is also in agreement with a subjective Dvorak satellite estimate from SAB. Aside from its relatively brief time passing over western Cuba, Ian will be moving over waters of very high oceanic heat content during the next couple of days. The various Rapid Intensification (RI) indices show a significant probability of RI and this is reflected in the short-term official intensity forecast. However, the SHIPS guidance, which is based on global model predictions, indicates that a significant increase in southwesterly shear and a substantially drying of low- to mid-level air will begin in 24-36 hours. The NHC forecast, like the previous one, shows strengthening to Category 4 intensity in a day or so, followed by gradual weakening. However, Ian is still expected to be a major hurricane when it reaches the Florida west coast. The official intensity forecast is near or above the latest simple and corrected multi-model consensus predictions. Ian continues its north-northwestward trek at about 340/11 kt. The hurricane is expected to move north-northwestward to northward over the southeastern Gulf of Mexico during the next day or so, along the western periphery of a subtropical ridge. After around 36 hours, the track forecast becomes more uncertain, since there is considerable divergence of the track models in the 2-3 day time frame. The guidance also shows considerable slowing of the forward speed, due to a weakening of the steering currents, when Ian approaches the west coast of Florida. This slower forward motion is likely to prolong the storm surge, wind, and rainfall impacts, especially along the west coast of Florida. The official track forecast is adjusted just slightly east of the previous NHC prediction based on the latest multi-model consensus aid, TVCN. Key Messages: 1. Life-threatening storm surge, hurricane-force winds, flash floods and possible mudslides are expected in portions of western Cuba beginning overnight and continuing into Tuesday. Devastating wind damage is possible where the core of Ian moves across western Cuba. Efforts to protect life and property should be rushed to completion. 2. There is a danger of life-threatening storm surge along much of the Florida west coast where a storm surge warning has been issued, with the highest risk from Fort Myers to the Tampa Bay region. Residents in these areas should listen to advice given by local officials. 3. Hurricane-force winds are expected in the hurricane warning area in west-central Florida beginning Wednesday morning with tropical storm conditions expected by late Tuesday. 4. Heavy rainfall will spread across western Cuba through Tuesday. This will likely produce instances of flash flooding and possible mudslides in areas of higher terrain over western Cuba. 5. Heavy rainfall will increase across the Florida Keys and South Florida Tuesday, spreading into central and northern Florida Wednesday and Thursday and the Southeast by Friday and Saturday, potentially causing flash, urban and small stream flooding. Considerable flooding, including significant, prolonged river flooding, is likely across Central Florida.

Hurricane Ian Special Discussion Number 15 NWS National Hurricane Center Miami FL AL092022 500 PM EDT Mon Sep 26 2022 Ian continues to strengthen over the northwestern Caribbean Sea. The last report from the Air Force Hurricane Hunters around 1630 UTC found 700-mb flight-level winds of 79 kt. The inner core appears better organized, and the eyewall structure has greatly improved in radar imagery from the Cayman Islands. The 18 UTC satellite classifications from SAB and TAFB were a consensus T4.5/77 kt, but the continued improvement in satellite structure warrants raising the initial intensity to 85 kt for this advisory. Atmospheric and oceanic conditions remain very favorable for additional intensification during the next 24 h or so, as Ian moves over the very warm waters of the northwestern Caribbean Sea and the southeastern Gulf of Mexico while the shear remains quite low. The NHC intensity forecast calls for Ian to become a major hurricane before it reaches western Cuba early Tuesday. It is then forecast to reach its peak intensity over the southeastern Gulf of Mexico in 36 h. After that, southwesterly shear in association with a deep-layer trough over the eastern U.S. is forecast to significantly increase over the hurricane on Wednesday and Thursday, which will likely disrupt the vertical structure and import drier air into its circulation. Despite these less favorable conditions, Ian is still forecast to remain at or near major hurricane strength as it passes near the west-central coast of Florida on Wednesday and Thursday. The NHC intensity forecast agrees well with the latest IVCN and HCCA aids. Ian has made an expected turn toward the north-northwest, and its initial motion is 330/11 kt. The hurricane will move north-northwestward to northward over the next day or so as it is steered by a mid-level ridge to the east. A turn to the north-northeast with a decrease in forward speed is forecast on Wednesday and Thursday as the center of Ian moves near the west coast of Florida. The slower forward motion is likely to prolong the storm surge, wind, and rainfall impacts, especially along the west coast of Florida. The latest track guidance has come into better agreement on this scenario, although it is noted that small deviations to the shore-parallel track could have large implications on the impacts at particular locations along the west coast of Florida. The NHC track forecast has again been adjusted slightly eastward at 48-72 h, which follows the latest trends in the global model guidance and lies near but just west of the multi-model consensus aids. Based on the latest forecast and timing of expected impacts, Hurricane and Storm Surge Warnings have been issued along the west coast of Florida. Key Messages: 1. Life-threatening storm surge, hurricane-force winds, flash floods and possible mudslides are expected in portions of western Cuba beginning this evening and continuing into Tuesday. Devastating wind damage is possible where the core of Ian moves across western Cuba. Efforts to protect life and property should be rushed to completion. 2. There is the danger of life-threatening storm surge along much of the Florida west coast where a storm surge warning has been issued, with the highest risk from Fort Myers to the Tampa Bay region. Residents in these areas should listen to advice given by local officials. 3. Hurricane-force winds are expected in the hurricane warning area in west-central Florida beginning Wednesday morning with tropical storm conditions expected by late Tuesday. 4. Heavy rainfall will increase across the Florida Keys and south Florida Tuesday, spreading to central and northern Florida Wednesday and Thursday, potentially causing flash, urban and small stream flooding. Significant prolonged river flooding is likely across central Florida.
