(RNN) - A tropical storm quickly formed in the Gulf of Mexico on Monday morning, and already has made landfall in Florida.
The National Hurricane Center said Tropical Storm Emily made landfall at Anna Maria Island, just west of Bradenton, FL, at 10:45 a.m. Eastern.
Tropical Storm Emily is located 10 miles northwest of Bradenton, FL, and 20 miles south of Saint Petersburg, FL, moving east at 9 mph, the National Hurricane Center said. It is packing maximum-sustained winds of 45 mph.
Emily will make landfall on the west-central Florida coast on Monday, forecasters said.
A Tropical Storm Warning was issued for the west coast of Florida from the Anclote River south to Bonita Beach, FL.
Tropical storm conditions are expected in this area, including rain accumulations of 2 to 4 inches between the Tampa Bay area and Naples, with isolated amounts of up to 8 inches possible, as well as strong winds.
Gov. Rick Scott declared a state of emergency for 31 counties expected to be affected by the storm.
Street and road flooding already has been occurring in Manatee and Sarasota counties near the Myakka River, the National Hurricane Center said.
A brief tornado, along with an isolated waterspout or two, is also possible in the southern Florida peninsula.
Forecasters expect the storm to turn northeast later Monday or Tuesday and increase in forward speed. It will then make its way across the Florida peninsula and reach the Atlantic Ocean.
Forecasters said the storm will weaken to a depression over land, but will become a tropical storm again in the Atlantic.
