Alberto made a Memorial Day landfall near Laguna Beach, Fla, just west of Panama City, andofficials warned of unsafe conditions even though its maximum sustained winds fell to 45 miles per hour.
Wednesday: What's left of Alberto will get pulled north then eventually east into an upper level trough of low pressure.
The National Weather Service in Morristown (NWS) is tracking bands of possibly flood level rains to come Tuesday with the storm.
A WIND ADVISORY remains in effect for areas along and east of I-65 through 2 p.m. Winds will be sustained at 15-25 miles per hour and gusts will reach 35 miles per hour.
Overnight, Subtropical Storm Alberto approaching the Florida panhandle slowed down to half its speed but didn't lose any of its strength, according to the National Hurricane Center. What had sprung up from the Gulf of Mexico as a subtropical storm was now a vast, soggy system trekking inland as it flung rain - heavy at times - all around the US southeast.
The storm's center is expected to move over Alabama on Monday night and Tuesday, the NHC said. Tropical storm warnings were up for parts of the Panhandle and the Alabama coast. Very little change in intensity or forward motion is expected by the time it makes landfall.
Forecasters warned heavy rain, flash flooding and unsafe surf posed the biggest threats as Alberto's ragged core made landfall near Laguna Beach in the Florida Panhandle.
Alberto is expected to drop 2 to 6 inches of rain through Thursday across much of the Southeast, with 12 inches possible in isolated areas.
Janet Rhumes and her group of friends from Kansas had been planning their Memorial Day weekend on Navarre Beach since October.
Mark Bowen, Bay County Emergency management director, said at a Sunday afternoon news conference that the concern isn't with storm surge due to the timing of landfall and the tides. If the weather is bad, they can go out to eat or watch the beach from their condo. Last year, there were 17 named storms, 10 of which became hurricanes; the first named storm was Arlene - a rare preseason tropical storm that arrived in April.
