Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Fri Sep 13 2024

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Gordon, located over the central tropical Atlantic Ocean. The
Weather Prediction Center is issuing advisories on Post-Tropical
Cyclone Francine, located inland over northeastern Arkansas.

Offshore the Southeastern U.S.:
A non-tropical area of low pressure could form this weekend along a
frontal boundary and gradually acquire subtropical or tropical
characteristics a few hundred miles off the southeastern U.S.
coastline. Thereafter, a subtropical or tropical depression could
form early next week while the system moves generally northwestward
toward the coast. Additional information on this system can be
found in products issued by your local National Weather Service
Forecast Office and High Seas Forecasts issued by the National
Weather Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...40 percent.

Issued at 500 PM AST Fri Sep 13 2024 868 WTNT42 KNHC 132039 TCDAT2 Tropical Storm Gordon Discussion Number 10 NWS National Hurricane Center Miami FL AL072024 500 PM AST Fri Sep 13 2024 Gordon continues to produce a convective canopy of cold cloud tops near -75 C mainly to the east of the center, due to some moderate westerly wind shear. An earlier AMSR2 microwave pass depicted some banding features forming as well. Subjective and objective Dvorak satellite intensity estimates have remained steady around 35 kt. Thus, the intensity remains 35 kt for this advisory. The tropical storm continues to deal with some westerly wind shear and has about 18 hours before encountering a drier airmass across the central tropical Atlantic. So the current forecast shows the potential for some slight strengthening before the unfavorable airmass. Models depict that the cyclones wind field will weaken and the system is forecast to weaken to a tropical depression. Simulated satellite depicts that the cyclone will struggle convectively through the middle part of the period and there is a chance that Gordon could degenerate into a remnant low. For now, the official forecast keeps the system as a tropical cyclone for the entire forecast period. Some recovery is possible by days 4 and 5 when the system reaches a slightly more moist, unstable and low-shear environment. Gordon is moving slightly slower toward the west-northwest at 290/9 kt. The system is approaching a weakness in the subtropical ridge which will cause the system to slow its forward speed and turn more westward by tonight. This slow westward to west-southwestward motion will continue through much of the forecast period. An amplified trough is forecast to move to the north of Gordon towards the end of the period which could cause a turn toward the northwest and northward by the end of the period. However, there is quite a spread in the model guidance towards the end of the period due to the differences in intensity and if Gordon is able to regain strength toward the end of the period. The latest NHC forecast track is slightly to the left of the previous and near the simple consensus aids.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Active Systems:
The National Hurricane Center is issuing advisories on
recently-upgraded Tropical Storm Gordon, located over the central
tropical Atlantic Ocean. The Weather Prediction Center is issuing
advisories on Post-Tropical Cyclone Francine, located inland over
northeastern Arkansas.

Offshore the Southeastern U.S.:
A non-tropical area of low pressure could form along a frontal
boundary a few hundred miles off the southeastern U.S. coastline
this weekend. Thereafter, the low may develop some subtropical or
tropical characteristics, and a subtropical or tropical depression
could form early next week while the system moves generally
northwestward toward the coast. Additional information on this
system can be found in products issued by your local National
Weather Service Forecast Office and High Seas Forecasts issued by
the National Weather Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...40 percent.

Northern Leeward Islands (AL94):
An area of low pressure near the Northern Leeward Islands is
producing limited shower and thunderstorm activity. Environmental
conditions, including the proximity of dry air, do not favor
development of this system and development is no longer expected
while it moves west-northwestward at about 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...near 0 percent.

Issued at 1100 AM AST Fri Sep 13 2024 000 WTNT42 KNHC 131438 TCDAT2 Tropical Storm Gordon Discussion Number 9 NWS National Hurricane Center Miami FL AL072024 Issued by the NWS Weather Prediction Center College Park MD 1100 AM AST Fri Sep 13 2024 While some west-northwesterly shear exists over the cyclone, a combination of Dvorak satellite estimates and improved structure on satellite imagery since earlier this morning has led to the depression being upgraded to Tropical Storm Gordon. The initial wind speed is set to 35 kt, based on consensus Dvorak estimates around that value. The initial motion is a little slower toward the west-northwest (295/10 kt). While a weakness in the subtropical ridge to the north of Gordon is becoming more pronounced due to the possible retrogression of an upper low to its east-northeast, this appears to be only slowing the storm down. The track guidance indicates that the cyclone should turn westward by tonight and move slowly throughout much of the forecast period. By days 4 and 5, an amplifying shortwave trough to the north could cause Gordon to gradually turn northwestward, assuming the system can re-intensify. The official forecast is close to the previous prediction during the first 60 hours, but then is adjusted westward on days 3 through 5 following the latest model trends. Gordon has some chance to intensify today before moving deeper into the moisture-starved environment across the tropical Atlantic, and some weakening is anticipated this weekend. While the shear isn't expected to be too hostile, any re-intensification during next week is expected to be slow, and there is a chance that Gordon could degenerate into a remnant low. For now, the official forecast keeps the system as a tropical cyclone for the entire forecast period. Some recovery is possible by days 4 and 5 when the system reaches a slightly more moist, unstable and low-shear environment.
