000 WTNT41 KNHC 121450 CCA TCDAT1 Tropical Depression Francine Discussion Number 16...Corrected NWS National Hurricane Center Miami FL AL062024 1000 AM CDT Thu Sep 12 2024 Corrected Frances to Francine in the first paragraph Francine has continued to weaken this morning as the center moves across central Mississippi. Surface observations indicate that the central pressure has risen to near 996 mb, with winds of 25-30 kt observed about 80 n mi east and northeast of the center. Based on these data, the initial intensity is decreased to 30 kt. The surface observations and satellite imagery also suggest that Francine is merging with a frontal zone, and it is expected to become a post-tropical low later today or tonight. It should be noted that while the forecast shows the surface cyclone dissipating by 48 h, the remnants of the circulation above the surface will persist beyond that time and continue the heavy rainfall threat. The initial motion is now 360/12. A continued northward to north-northwestward motion with a decrease in forward speed is expected before dissipation, bringing Francine or its remnants across northern Mississippi into northeastern Arkansas. This is the last Tropical Cyclone Discussion issued by the National Hurricane Center on this system. Future information on this system can be found in discussions issued by the Weather Prediction Center beginning at 400 PM CDT, under AWIPS header TCDAT1, WMO header WTNT41 KWNH, and on the web at www.hurricanes.gov. Rainfall forecasts for the United States can always be found at https://www.wpc.ncep.noaa.gov/qpf/qpf2.shtml and outlooks of flash flood risks can be found at https://www.wpc.ncep.noaa.gov/qpf/excessive_rainfall_outlook_ero.php KEY MESSAGES: 1. Elevated water levels and high surf along portions of the Louisiana and Mississippi coasts should subside today. Until this occurs, residents in the affected area should continue to follow advice given by local officials. 2. 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. Considerable flash and urban flooding is possible through tonight over portions of Alabama and the Florida Panhandle, expanding into Georgia and middle Tennessee Friday.

371 WTNT42 KNHC 121449 TCDAT2 Tropical Depression Seven Discussion Number 5 NWS National Hurricane Center Miami FL AL072024 Issued by the NWS Weather Prediction Center College Park MD 1100 AM AST Thu Sep 12 2024 Tropical Depression Seven looks more organized on satellite imagery this morning, with a compact circulation and a small curved band with some deep convection. Subjective and objective Dvorak numbers indicate the system is close to becoming a tropical storm. However, given the relatively small size of ongoing convection near the center, the initial intensity was conservatively held at 30 knots, or at the lower end of the estimates. The cyclone continues on a west-northwestward heading, and the general motion is expected to continue over the next 2-3 days. The forward speed should gradually slow as the subtropical ridge to the north of the system weakens. Track guidance diverges considerably early next week, related to uncertainties with an amplifying trough over the north-central Atlantic Ocean and another ridge centered northeast of the Leeward Islands. This track forecast stays close to the global model consensus and places less weight on the regional hurricane models which depict a considerably weaker and less organized system. This produces a track forecast that is slightly faster and to the left of the previous forecast. While environmental conditions are somewhat favorable for gradual strengthening, with low-moderate vertical wind shear and marginally warm SSTs, intensity guidance came in lower for this cycle. We show the system becoming a tropical storm in the next day, followed by the intensity only slowly increasing to 45 knots in the next five days. However, there is potential for greater strengthening beyond what is shown early next week as the cyclone will be in an environment characterized by lower shear, warmer SSTs around 28C, slightly more instability, but plentiful dry air aloft. The new forecast is a little lower than the previous one, but above the latest model consensus.

The depression is moving toward the north near 14 mph (22 km/h), and this general motion is expected to continue with a decrease in forward speed through Friday. On the forecast track, the center of Francine will move over central and northern portions of Mississippi this afternoon and tonight and move into northeastern Arkansas by Friday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Weakening is forecast, and Francine is expected to become a post-tropical cyclone later today or tonight. The estimated minimum central pressure based on surface observations from the Jackson area is 996 mb (29.42 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 few hours over portions of central Mississippi and western Alabama. RAINFALL: Francine is expected to bring storm total rainfall of 4 to 8 inches across portions of Mississippi, eastern Arkansas, Tennessee, Alabama, Georgia and the Florida Panhandle. Localized amounts of 12 inches are possible over portions of Alabama, the Florida Panhandle, and Georgia. This rainfall could lead to 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: Water levels remain elevated along the Gulf coast between eastern Louisiana and Alabama but will recede through this afternoon. TORNADOES: A few tornadoes are possible today across the Florida Panhandle, southern and central Alabama, and southwest Georgia. SURF: Swells generated by Francine should subside along 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 ------------- This is the last public advisory issued by the National Hurricane Center on this system.

000 ABNT20 KNHC 121152 TWOAT 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. $$ Forecaster Hagen
