Alberto is a still-menacing depression after its Memorial Day landfall on the Gulf Coast, scattering heavy rains around the South and raising risks of flash floods.
Severe Subtropical Storm Alberto - the first named storm of the 2018 Atlantic Ocean hurricane season - is bearing down on the southeastern U.S., as states of emergency have been declared along coastal regions.
The storm's center is expected to move over Alabama on Monday night and Tuesday, the NHC said.
In its 7 p.m. advisory the National Hurricane Center said the center of Alberto was about 15 miles north of DeFuniak Springs and was moving north at 10 mph.
The storm's effects were being felt in South Florida, in the Keys and across the state, with 1 to 3 inches of more rain expected Monday, forecasters said, in areas already saturated from an above-normal rainfall in May.
"We're not expecting the season to be one of the most active on record", said Gerry Bell, lead hurricane season forecaster with NOAA's Climate Prediction Center.
Alberto dumped between 2 and 5 inches of rain over parts of the Florida Panhandle, according to the National Weather Service. The center of the storm will basically cut the state in half, with the east side of the state dealing with the worst of the impacts.
A tropical storm warning was in effect for a stretch of coastline between the Aucilla River in Floridas Big Bend and the Alabama-Florida border.
Subtropical Storm Alberto bearing down on Florida's coastline Sunday. The storm, coming on the last day of the Memorial Day weekend, was expected to scramble holiday travel.
Rough conditions were roiling the seas off the eastern and northern Gulf Coast region, and officials warned swimmers to stay out of the water through Tuesday due to life-threatening swells and rip currents. Officials there are warning of risky conditions.
Along the Florida Panhandle, tourists vowed Alberto wouldn't dampen their vacations. "So how often can you say you rode a storm out?" A lot of them will be lighter in nature this morning, with afternoon showers or thunderstorms that develop containing potential for heavier downpours.
Even with subtropical storm Alberto heading for the Panhandle, most locals and visitors alike were not letting it spoil their Memorial Day weekend on Sunday.
Tryon Fire Chief Geoffrey Tennant said he had just given an interview to Mr McCormick when, minutes later, he received a call about the incident. Warnings about storm surges and high surf were aired along the coast on either side of Apalachicola on Monday.
