Cover your grills and bring in the table umbrellas. Tropical storm force winds ahead of Subtropical Storm Alberto are expected to make landfall Sunday night and the storm is pushing a good deal of wind and rain out out toward the Lowcountry, too.
Alberto made a slightly north-northwestward turn Sunday afternoon and gained a bit of strength in the early evening, according to the National Hurricane Center
The storm system passed Cuba on Saturday and was about 105 miles south of Apalachicola, Fla. moving slowly but surely toward the Florida panhandle at about 12 mph with maximum sustained winds of 65 mph Sunday evening, according to the National Hurricane Center around 7 p.m. on Sunday. At 11 a.m. it was moving at 14 mph and was 130 miles west southwest of Tampa. Sustained winds within the storm had been steady at 50 mph so much of the day.
In a live video on Facebook just after 11 a.m., National Hurricane Center Director Ken Graham gave updates on the storm Sunday morning. He said Alberto was likely to slow down as it meets land in Florida and Alabama, but heavy tropical showers are expected all across Florida.
In a second live video just after 5 p.m., Graham pointed to the slight shift in the storm's path which didn't hamper any of it's momentum. "Deep tropical moisture" should be expected in much of South Carolina as the storm make landfall and continues to move north. There is a marginal risk for tornadoes in the Lowcountry and a higher risk fore even more rain as the storm slows down..
Tropical storm force winds will meet land by about 8 p.m. Sunday and the storm itself is likely to make landfall Monday morning. Much of the Southeast should expect 2 to 4 inches of rain over the next couple of days. Winds of that strength are only expected to reach mid-Georgia and shouldn't be that strong once they get to the Lowcountry.
Off the East Coast, there is a potential for high winds and wave heights as Alberto rolls through. Anyone thinking about going out onto the water is urged to use caution.
Sunday afternoon and evening are expected to bring heavy rain and winds between about 15 and 18 mph, according to the National Weather Service in Charleston. Thunderstorms are possible overnight, bringing 1 to 2 inches of rain.
There is a moderate risk for rip currents for the coastal areas of the Lowcountry through Sunday night. With heavy rains and rising tides, some flooding is also a possibility.
More showers and possibly another thunderstorm in the afternoon are possible on Monday, Memorial Day. Winds will have died down to about 11 mph and there should be a high of 82 degrees during the day. Only a half-inch or less of rain is expected for Monday and the chance of rain will decrease from 70 percent to 40 percent as the day turns into evening.
The Savannah River is expected to flood near Clyo, Georgia as early as Monday morning and the effects are forecast to be seen in Jasper and Hampton counties in South Carolina, according to a news release from the City of Hardeeville. By Sunday morning the water was already at 10.5 feet, with flooding officially starting at 11 feet. Flood waters are expected to rises to approximately 11.7 feet by Wednesday morning.
Showers and thunderstorms will be possible throughout the week, with high temperatures in the mid to low 80s and abundant clouds all the while.
