Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Thu Sep 12 2024

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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Depression Francine, located inland over south-central Mississippi,
and on Tropical Depression Seven, located over the eastern Atlantic
Ocean.

Central Tropical Atlantic (AL92):
A weak area of low pressure located several hundred miles east of
the Leeward Islands is producing limited shower and thunderstorm
activity. Development of this system is not expected while it moves
westward at around 10 mph over the central tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...near 0 percent.

East of the Leeward Islands (AL94):
Showers and thunderstorms have become a bit more concentrated in
association with a small area of low pressure located a few hundred
miles east of the Leeward Islands. However, the proximity of dry
air near the system is expected to limit additional development
over the next couple of days. Environmental conditions are expected
to become even less conducive over the weekend while the system
moves slowly west-northwestward.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.

Offshore the Southeastern U.S.:
In a few days, a non-tropical area of low pressure could form along
a residual frontal boundary a few hundred miles off the southeastern
U.S. coastline. Thereafter, some subtropical or tropical development
is possible during the early part of next week while the system
drifts to the north or northwest.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Warning is in effect for... * The mouth of the Pearl River to the Mississippi/Alabama Border * Lake Maurepas * Lake Pontchartrain A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 700 AM CDT (1200 UTC), the center of Tropical Depression Francine was located near latitude 31.9 North, longitude 90.1 West. Francine is moving toward the north-northeast near 12 mph (19 km/h). A turn toward the north is expected during the next day or so, with some decrease in forward speed. On the forecast track, the center of Francine will move over central and northern portions of Mississippi through early Friday. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Continued weakening is forecast, and Francine is expected to become a post-tropical cyclone later today. The estimated minimum central pressure is 996 mb (29.41 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Francine can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header WTNT41 KNHC. WIND: Wind gusts to tropical-storm force are possible for the next several hours over portions of southeastern Louisiana, southeastern and central Mississippi, and southwestern Alabama. RAINFALL: Francine is expected to bring storm total rainfall of 3 to 6 inches across portions of Mississippi, eastern Arkansas, Tennessee, Alabama, Georgia, and the Florida Panhandle. Localized amounts up to 10 inches are possible within rain bands over portions of central and northern Alabama and over the Florida Panhandle. This rainfall could lead to locally considerable flash and urban flooding. For a complete depiction of forecast rainfall associated with Francine, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at1.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at1.shtml?ero. For a list of rainfall observations (and wind reports) associated this storm, see the companion storm summary at WBCSCCNS1 with the WMO header ACUS41 KWBC or at the following link: www.wpc.ncep.noaa.gov/discussions/nfdscc1.html. STORM SURGE: The combination of a dangerous 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... Mouth of the Pearl River, LA to MS/AL Border...2-4 ft Lake Pontchartrain and Lake Maurepas...2-4 ft The deepest water will occur along the immediate coast near and to the east of the landfall location, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. 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_at1.shtml?peakSurge. TORNADOES: A few tornadoes are possible today, mainly this morning and afternoon from the Florida Panhandle to north-central Alabama. SURF: Swells generated by Francine will continue to affect much of the northern Gulf coast through 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 complete advisory at 1000 AM CDT. $$ Forecaster Beven

The system is highly sheared due to its interaction with a mid- to upper-level trough to the northwest. Francine is quickly losing tropical characteristics, and surface observations indicate the surface center is located south and west of the heaviest rainfall. Tropical storm conditions, especially in gusts, continue over portions of the northern Gulf Coast within the warning area. Earlier scatterometer data showed 35-40 kt offshore winds, and the initial intensity is lowered to 40 kt. The storm has slowed down a bit and is now moving northeastward at about 10 kt. Francine is expected to turn north-northeastward and northward today, bringing the center across central and northern Mississippi. Continued weakening is expected, and tropical storm conditions along the coasts of southeastern Louisiana, Mississippi, and Alabama are likely to subside this morning as the low weakens and moves further inland. Given its degraded satellite structure, Francine is likely to degenerate to a post-tropical low as early as this morning, with dissipation forecast to occur by 48 h. An experimental cone graphic that includes inland Hurricane and Tropical Storm Watches and Warnings in the U.S. is now available on the NHC website. Due to the time needed to compile the inland watch and warning information, the experimental cone graphic will not be available as quickly as the operational cone. Once it is available, the experimental cone graphic can be found from a red weblink above the operational cone graphic at https://www.nhc.noaa.gov/graphics_at1.shtml?cone#contents. Users are encouraged to take the experimental product survey found below the experimental cone. KEY MESSAGES: 1. There is a danger of life-threatening storm surge during the next several hours for portions of the eastern Louisiana and Mississippi coastlines, where a Storm Surge Warning remains in effect. Residents in the warning area should continue to follow advice given by local officials. 2. A Tropical Storm Warning remains in effect for coastal portions of southeastern Louisiana, Mississippi, and Alabama, where tropical storm conditions could continue for the next few hours. 3. Francine will continue to bring heavy rainfall and the risk of flash and urban flooding, along with river flooding, across portions of the Lower Mississippi Valley, Tennessee Valley, and the Southeast. Locally considerable flash and urban flooding is possible today and tonight over portions of central and northern Alabama and the Florida Panhandle.

Issued at 500 AM AST Thu Sep 12 2024 000 WTNT42 KNHC 120846 TCDAT2 Tropical Depression Seven Discussion Number 4 NWS National Hurricane Center Miami FL AL072024 500 AM AST Thu Sep 12 2024 The system has changed little in organization overnight, with limited deep convection and slight banding features. An AMSR-2 microwave image suggested that the circulation was still somewhat broad since the cloud bands were not very tightly curved. Subjective Dvorak classifications from TAFB and SAB were T2.5/35 kt and T2.0/30 kt, respectively. The advisory intensity is held at 30 kt given the depression's lack of increased organization. This is also in agreement with a DMINT objective intensity estimate from UW-CIMSS based on the AMSR data. The cyclone continues on a west-northwestward heading with an estimated motion of 290/15 kt. A gradually weakening ridge over the eastern subtropical Atlantic should maintain this general motion with decreasing forward speed over the next 2-3 days. Later in the forecast period, an amplifying trough is expected to erode the ridge, which should cause the cyclone to turn at least a little to the right. The track guidance becomes somewhat divergent in the 4- to 5-day time frame, but is in overall agreement on a rather slow motion. The official track forecast is similar to the previous NHC prediction and close to the various dynamical model consensus solutions. Environmental conditions seem fairly conducive for at least gradual strengthening during the next few days, with low- to moderate-vertical wind shear and marginally warm SSTs. However, the models are not very bullish on strengthening until near the end of the forecast period. This may be due to a somewhat stable air mass over the eastern Atlantic. The official intensity forecast is similar to the Decay-SHIPS model guidance through 72 hours, but shows no change after that time given the uncertainties in intensity prediction.
