National Hurricane Center: The National Hurricane Center (NHC) has upgraded the formation chance of a low-pressure system in the northeastern Gulf of Mexico, designated as Invest 91-L, to an 80% chance of becoming a tropical cyclone over the next 48 hours. Forecasters note that a tropical depression is highly likely to form as the system tracks slowly north or northwestward.

National Hurricane Center: Florida on Alert as US Hurricane Center Sees Higher Chance of Cyclone

The National Hurricane Center (NHC) has issued an updated advisory raising the development chances for Invest 91-L to a high 80% chance over both the next 48 hours and the next 7 days. Positioned in the northeastern Gulf of Mexico, the low-pressure system continues to gain organization, and a tropical depression is officially expected to form between Sunday and Monday as it slowly drifts north-northwest.

National Hurricane Center: Current Status

National Hurricane Center: Expected Regional Impacts

  • Heavy Rainfall & Flooding: The primary threat is flash flooding driven by slow-moving, repeated downpours. Central Florida, the Florida Panhandle, and the west coast are expected to see significant precipitation totals.

  • Gusty Winds: Wind gusts up to 55 mph are possible within localized training rain bands.

  • Watches & Warnings: The NHC has indicated that tropical storm watches or warnings could be issued for portions of the northern Gulf Coast, including Florida, Alabama, Mississippi, and Louisiana.

National Hurricane Center: Atmospheric Conditions & Strengthening

  • Fuel Source: The system is spinning over exceptionally warm Gulf waters, which provide the thermal energy needed for deep thunderstorm organization.

  • Wind Shear: The system currently faces modest wind shear in the northern Gulf. However, as it drifts west-northwestward into areas of lower shear, conditions will become more favorable for further intensification into Tropical Storm Bertha.

  • Reconnaissance: An Air Force Reserve Hurricane Hunter aircraft is officially scheduled to fly directly into the center of the storm to locate a closed surface circulation and measure exact wind speeds.

National Hurricane Center: Targeted Rainfall & Flood Risks

  • Tampa & West Coast: Already receiving heavy rain, coastal regions from the Tampa Bay area up through the Big Bend are forecast to pick up 6 to 8 inches of rain over the next few days.

  • Panhandle & Central Florida Shift: Spaghetti models have consolidated on a westward-drifting track. This shifts the core flood risk away from inland Central Florida (Orlando) and aims it squarely at the Florida Panhandle and coastal Alabama and Mississippi.

National Hurricane Center: Tax-Free Hurricane Supplies

For those in Florida purchasing last-minute items, remember that the state permanently eliminated sales tax on specific storm readiness items. You can buy tax-free essentials including bottled water, first aid kits, fuel cans, and weather radios.
