The National Hurricane Center said a tropical depression is likely to form in the Gulf of Mexico by the end of the week.
The NHC said the disturbance has an 80% chance to form into a depression through Saturday. The formation chance through the next two days is low – at 10%.
The trough of low pressure over central Georgia is forecast to move southward toward the northeastern Gulf Coast where a broad area of low pressure will form in a couple of days, according to the NHC.
"Some gradual development is possible thereafter and a tropical depression is likely to form by the end of the week while the low meanders near the northern Gulf Coast," the NHC said in a statement. "Regardless of development, this system has the potential to produce heavy rainfall along portions of the northern and eastern U.S. Gulf Coast later this week."
No impact to South Florida is expected.
To help its residents prepare for the rain, the city of Tallahassee has opened four sandbag distribution centers.
Florida Gov. Ron DeSantis on Monday urged Floridians to be prepared.
He says residents in north and central Florida should be ready for heavy rain and the potential for flooding in low-lying areas.
