Alberto's wide spinning rain bands dumped 2 to 3 inches in the Lowcountry, then left a steamy forecast in its wake.
The first named storm of the year, Alberto plowed into Florida's Panhandle with 60 mph winds Monday afternoon. It was still subtropical when it made landfall, meaning it had similarities to a rotating tropical storm and a garden variety low pressure system.
No matter the definition, subtropical storms tend to have strong winds and storms far from the center. That was the case with Alberto’s impact on South Carolina.
Some of the heaviest rains hit late Sunday, with up to 1.5 inches falling in downtown Charleston and up to 3 inches West of the Ashley. Low-lying streets flooded in downtown Charleston.
Police put up barricades around the city’s Market.
By Monday morning, floodwaters had receded and the barricades were moved aside.
Forecasters said Alberto will track north through Alabama and Georgia, more than 300 miles away from South Carolina. But it will still have an effect here, drawing moisture from the south and creating ripe conditions for isolated but heavy downpours for the rest of the workweek.
"We're going to return to a more typical afternoon thunderstorm schedule," said Emily McGraw, a forecaster with the National Weather Service in Charleston.
The storm caused little damage other than to people's plans to be outdoors. Only a handful of power outages were reported statewide Monday night.
The city of Charleston canceled a patriotic concert in Marion Square on Monday, and crowds were light on Folly Beach as several squalls passed through.
Alberto's relatively light touch in the Lowcountry was a soggy beginning for the unofficial beginning of summer and a head-start for the hurricane season, which officially begins June 1.
