Kevin Reilly Posted August 3 Share Posted August 3 Just now, cptcatz said: I'm not sure why this is a weenie take. The storm has a clear low level center with convection popping overhead, and will be traversing some of the hottest water in the world right now for the next 400 miles, along with what appears to be good atmospheric conditions. This along with GFS showing a landfall pressure of 983, I think cat 2 is clearly on the table right now. 100% agree with this and the warm waters remember Charlie and Ian DO NOT downplay this situation take it as a serious threat!

traindog71 Posted August 3 Share Posted August 3 I remember going to the Binghamton area, vestal specifically, with my fire dept and several others from long Island after Irene. What a rain flooding disaster then.... This will be far more wide spread kinda setup with many states affected potentially.That was actually a result of Tropical Storm Lee. Which hit a couple weeks after Irene. . Link to comment Share on other sites More sharing options...
wthrmn654 Posted August 3 Share Posted August 3 Euro kinda looks more like what the gfs been saying, for a while where it goes off the coast again by Virginia and hits the northeast stronger again with a glancing hit.. but ton of rain Link to comment Share on other sites More sharing options...

purduewx80 Posted August 3 Share Posted August 3 You can see the implied impacts of downsloping off Cuba’s mountains, with dry air being maintained into northern parts of the circulation. Once that convection on the southern end builds around, we should see it intensify at a pretty good clip. 18Z SHIPS upped the prob of 25KT/24hours to 33% and 65 KT prior to landfall at 25%. 8 1 Link to comment Share on other sites More sharing options...

Prospero Posted August 3 Share Posted August 3 Another band is inching this way from the south. I've finished the work I need to do in order to have 15 minutes or so to close the last shutters in the unlikely event I will need to. But Charlie caught so many off guard and taught everybody on the Central West Coast of Florida so many lessons about being casual when any kind of storm passes by. Being a season since I've hung out here and only popping in to read now and then, I am wondering when a Banter and/or Conditions forum might appear. I am not a Met, just a passionate Enthusiast who is getting excited. Right now that feeling of a broad circulation is very familiar to we who live on the Gulf Coast is invigorating. It's like we can feel a storm approaching. I can hear the trees and ground beneath me cheering for the seasonal rain we need from these storms. Yay!

yoda Posted August 3 Share Posted August 3 Tropical Storm Debby Discussion Number 6 NWS National Hurricane Center Miami FL AL042024 500 PM EDT Sat Aug 03 2024 The tropical cyclone has become better organized since the last advisory, with the circulation center becoming better defined over the southeastern Gulf of Mexico and areas of outer convective banding to the north and south of the central region. A combination of earlier scatterometer data, surface observations in the Florida Keys, and ship reports in the Straits of Florida shows an area of 30-35 kt winds located about 120 n mi from the center in the eastern semicircle. Based on this information, Tropical Depression Four is upgraded to Tropical Storm Debby. The initial motion is now northwest or 310/13 kt. A large mid- to upper-level trough over the central United States is creating a break in the subtropical ridge, and Debby is expected to turn northward into this break in about 24 h. This should be followed by a gradual turn toward the northeast at a slower forward speed through 60 h. This motion should bring the center near or over the northern Gulf coast in roughly 48 h. After landfall, weakening steering currents should cause the cyclone to slow down while it moves northeastward or eastward over parts of northern Florida and Georgia. The uncertainty in the forecast increases significantly after 60 h as the cyclone interacts with a portion of the U.S. trough. The latest GFS and ECMWF models show a slow eastward motion into the Atlantic, followed by a turn toward the north or northwest that brings the center back inland. On the other hand, the Canadian model is still forecasting Debby to move slowly northeastward across the southeastern states and does not bring it over the Atlantic. This portion of the new forecast track continues to show a slow motion and leans toward the GFS/ECMWF solutions. Conditions are favorable for strengthening over the Gulf of Mexico with warm sea surface temperatures and light shear. Intensification is likely to be slow during the first 12-24 h, then proceed at a faster rate after the cyclone develops an organized inner core. The new intensity forecast calls for a peak intensity of 65 kt at landfall on the Gulf coast of Florida in best agreement with the HWRF model. Weakening is forecast after landfall while the system moves over the southeastern United States. Beyond 72 h, the intensity forecast remains quite uncertain due to the possibility of land interaction and how much interaction will occur with the aforementioned mid-latitude trough. Key Messages: 1. Heavy rainfall will likely result in considerable flash and urban flooding across portions of Florida and the coastal areas of the Southeast this weekend through Thursday. Significant river flooding is also expected. 2. Hurricane conditions are expected on Monday along portions of the Florida Big Bend region where a Hurricane Warning is in effect, with tropical storm conditions beginning late Sunday. Tropical storm conditions are expected through Monday farther south within the Tropical Storm Warning along Florida's west coast, including the Tampa Bay area and the Lower Florida Keys. 3. There is a danger of life-threatening storm surge inundation along portions of the Gulf coast of Florida from Aripeka to Indian Pass. Life-threatening storm surge is possible south of Aripeka to Bonita Beach, including Tampa Bay and Charlotte Harbor. 4. Impacts from storm surge, strong winds, and heavy rains are possible elsewhere in Florida and along the southeast coast of the United States from Georgia to North Carolina through the middle of next week, and interests in those areas should continue to monitor the progress of this system. Additional watches and warnings will likely be required tonight or on Sunday.

Normandy Posted August 3 Share Posted August 3 I’m in the camp of “intensity forecasts are way underdone”. Can’t rule out a major at first landfall. It’s way way ahead of schedule and deepening quickly already. Models have always suggested this will be deepening on approach, suggestive of a favorable environment. I am interested in where the stall occurs. Link to comment Share on other sites More sharing options...

hlcater Posted August 3 Share Posted August 3 Starting to wonder if this starts building an inner core sooner rather than later. The surface circulation is already well defined and appears to be becoming stacked under the sprawling mid-level circulation. This process seems to be complicated only by dry entrainment off of Cuba’s higher terrain, with deep convection widespread in all 4 quadrants otherwise. I’m not seeing much reason why a quicker pace of intensification shouldn’t ensue once that gets mixed out, especially if convection continues to develop over the center.

taylorsweather Posted August 3 Share Posted August 3 Hydrology disco out of CHS: .HYDROLOGY... While there are still uncertainties regarding the track, timing, and strength of Debby, there is increasing confidence that the system will produce a rare and uncommon rainfall and flooding event across southeast GA and southeast SC. The setup is quite ideal for a prolonged widespread intense rainfall event with precipitable water values surging to 2.5 inches or greater and a near stationary or slowly meandering system that is expected to be strengthening while in close proximity to the GA/SC coast. Sunday rainfall will mostly (if not completely) be convectively driven and independent of the circulation envelope around Debby. We currently expect the outer bands of the system to begin spreading into southeast GA as soon as Sunday night and definitely into Monday. From there, the heavy rainfall threat will persist until the system exits the area, which might not be until Friday. Broadly speaking, rainfall totals are expected to be in the 6-12 inch range across all of southeast GA/SC, with 8-12 inches along the coastal corridor. Locally higher amounts of up to 18 inches are expected. If these rainfall amounts come to fruition, we can expect to see widespread considerable flash flooding across the area, especially along the coastal corridor with the threat being heightened around the metro areas of Savannah, Beaufort/Hilton Head, and Charleston. With these rainfall totals, the expected impacts will likely include flooded homes and structures, damages to roadways including washouts, and uncommon flooding along smaller creeks and streams. Rainfall will likely come in bands with periods of very intense rainfall followed by periods of light rain or even no rain at times. Unfortunately, it is still too early to highlight specific time periods of when the most intense rainfall could occur. Timing details, as well as adjustments to the rainfall totals, can be expected in subsequent forecast updates. 1 Link to comment Share on other sites More sharing options...

Looking at Satellites Debby is very symmetrical. Almost if you use your imagination it’s ready to pull everything to the center. Link to comment Share on other sites More sharing options...
Prospero Posted August 3 Share Posted August 3 5 minutes ago, Amped said: Hurricane Ian made a turn into the SC coast but it wasn't as sharp. I suspect this turn is being overdone by models and it ends up over E NC day 5. ChatGPT (AI): There have been several notable hurricanes in the Gulf of Mexico that made a "hard right turn," meaning they changed direction sharply, usually turning toward the northeast or east after moving westward or northward. Here are a few examples: 1. Hurricane Charley (2004) Path: Charley moved northwest across the Caribbean and then turned sharply to the right as it entered the Gulf of Mexico, making landfall in southwest Florida near Punta Gorda as a Category 4 hurricane. This sharp turn caught some forecasters and residents off guard as the hurricane had been predicted to take a more westerly track. 2. Hurricane Elena (1985) Path: Elena exhibited a very unusual path. It initially moved northwest in the Gulf of Mexico, then stalled and made a sharp right turn toward the east, heading toward the Florida Panhandle. It made landfall near Biloxi, Mississippi, after meandering in the Gulf and threatening multiple states. 3. Hurricane Michael (2018) Path: Michael moved northward through the Gulf of Mexico and then made a hard right turn toward the northeast before making landfall in the Florida Panhandle near Mexico Beach as a devastating Category 5 hurricane. 4. Hurricane Ivan (2004) Path: After moving northwest across the Gulf of Mexico, Ivan made a hard right turn toward the northeast, making landfall near Gulf Shores, Alabama. It then continued inland before looping back into the Atlantic, turning into a subtropical storm, and eventually curving back across Florida. 5. Hurricane Opal (1995) Path: Opal moved northwest across the Gulf before making a sharp right turn toward the northeast. It intensified rapidly just before landfall and struck near Pensacola, Florida, as a Category 3 hurricane. These examples illustrate how unpredictable hurricane paths can be, particularly in the Gulf of Mexico where weather patterns can lead to sudden changes in direction.
