Alberto, the first named Atlantic storm of 2018 which spun up days before the formal start of the 2018 hurricane season, is expected to intensify and bring wind speeds of up to 65 miles per hour (40 kph) to the Gulf Coast when it approaches over the holiday on Monday, the National Weather Service said.
On its current forecast track, Alberto is expected to continue its slow journey north until making a turn to the northwest Monday as it approaches the north-central Gulf coast, the hurricane center said.
The subtropical storm, the first named storm of the season, is expected to spread tropical storm conditions along the west coast of Florida Sunday.
Forecasters say heavy rains from Subtropical Storm Alberto could cause flooding across most of SC.
At 7:30 p.m. EDT Sunday, Alberto was centered about 195 miles (315 kilometers) west of Tampa and had maximum sustained winds of 65 mph (100 kph) - up from 50 mph (85 kph) earlier.
Alberto's track shifts east and forecast changes for Mississippi Coast
A more widespread area of rain and embedded storms will arrive early Tuesday and last all day before Alberto moves north of Alabama by Wednesday. The main threat is from heavy rain that could lead to flooding, the city said, but also high winds and storm surge could cause problems.
The storm disrupted long holiday weekend plans from Pensacola in the Florida Panhandle to Miami Beach on Florida's southeastern edge.
The hurricane centre said Sunday that a tropical storm warning was in effect from Bonita Beach, Fla., to the Mississippi-Alabama border. Rainfall totals of between 100-250 mm with up to 380 mm, are possible from eastern Louisiana to Mississippi, Alabama, western Tennessee and the western Florida panhandle, the NWS said. In contrast to a tropical storm or hurricane, where the strongest winds are at the center, a subtropical storm can have the most powerful winds far from the core. At the moment nearly all of the showers are on the east of Alberto's centre, with the heaviest rains falling across Cuba and Florida.
Cuba is expected to get as much as 15 inches of rain, the hurricane center said in an advisory Saturday, and the Florida Keys and South Florida could get as many as 10 inches. However, there is a low chance for spotty showers across our western and northern zones.
