Thunderstorms toppled trees in Dorchester County on Thursday afternoon and generated another flood advisory in Charleston on Thursday night.
The storms swept through the Summerville area Thursday afternoon with up to 2 inches of rain and wind gusts around 35 mph, according to the Charleston office of the National Weather Service. That was enough to bring down trees.
A tree fell on a house on Holly Avenue in Summerville, according to the sheriff's office. No injuries were reported.
Another tree fell on U.S. Highway 78 near West Meadow Drive in Ridgeville.
The storm moved into the Mount Pleasant area later in the day. Two power lines fell along U.S. Highway 17 between Dragoon Drive and Anna Knapp Boulevard about 7:15 p.m. Thursday. It was not immediately clear if it was because of the storm, but no wrecks that could have cause it were reported, according to police.
High tide in Charleston Harbor was at 9:29 p.m. Thursday, and the weather service expected streets to flood.
Friday's forecast called for sunny skies and a high near 80 degrees, but unusually cool temperatures were expected Friday night.
The weather service was predicting a low of 51 degrees in Charleston and 49 degrees in the Summerville area. That's not a record low but pretty close to it for this time of year. The record low on Friday's date was 49 degrees at Charleston International Airport in 1984, and Summerville would have been a couple degrees cooler, weather service meteorologist Richard Thacker said.
The mercury is expected to bounce back up into the high 70s Saturday.
