Heavy rain and flash flooding are possible in parts of the Florida peninsula.
Tropical Storm Emily has formed just off Florida's Gulf Coast and is poised to deliver more soaking rain to parts of Florida through Tuesday.
The National Hurricane Center early Monday morning initiated advisories on Tropical Depression Six. Two hours later, Doppler radar suggested the tiny circulation had developed winds strong enough to merit an upgrade to "Emily", the fifth named storm of the 2017 Atlantic hurricane season.
A tropical storm warning was posted to include the majority of the Tampa/St. Petersburg metro area from Pinellas County southward to Lee County.
There are a few clusters, including one in the main development region (MDR), off the west coast of Africa into part of the Caribbean. Activity here is usually greatest from August into September.
Two other areas common for development early in the season are closer to the U.S. – in the western Gulf of Mexico and off the Southeast coast.
In June, some of the activity in the Gulf of Mexico and off the Southeast coast comes from decaying cold fronts. In July, cold fronts become much less frequent but thunderstorm complexes rolling off the Southeast coast can linger and lead to tropical cyclone formation.
As hurricane season progresses, tropical waves start coming off the coast of Africa.
