Monitoring Invest 99L | Summary
Posting Date: August 26, 2021, 10:00:00 AM
At 8 a.m. EDT, the National Hurricane Center (NHC) issued a Tropical Weather Outlook reporting on the status and forecast for Invest 99L, which is expected to become a tropical depression or tropical storm later today or tonight. If this system were to be named, it would be called Ida and would be the ninth named storm of the Atlantic hurricane season.
The system of showers and thunderstorms continues to show signs of organization and is located over the west-central Caribbean Sea, about 150 miles south-southwest of Jamaica. As it moves northwestward over the northwestern Caribbean Sea, it is forecast to reach the Cayman Islands tonight and western Cuba and the Yucatan Channel tomorrow and tomorrow night. Tropical Storm Warnings may be required for the Cayman Islands and western Cuba later this morning. Regardless of how this system develops, locally heavy rainfall and flooding are possible over parts of Jamaica and the Cayman Islands today and tonight, and will likely spread across Cuba and the Yucatan Peninsula tomorrow.
The system is expected to enter the Gulf of Mexico tomorrow night and continue on its northwest track, potentially bringing dangerous impacts from storm surge, wind, and heavy rainfall to areas along the coasts of Texas, Louisiana, Mississippi, Alabama, and the Florida Panhandle by Sunday and Monday.
Uncertainty in the system’s track and intensity remains large, however, as it is just beginning to organize. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system this afternoon.
