Charleston got drenched twice Tuesday night.

A torrential downpour flooded Charleston streets and snarled traffic around 7 p.m.

The rain was worse than when Tropical Storm Andrea passed through last week.

The downpour dumped about 1.5 inches of rain on the Charleston area in less than an hour, according to the National Weather Service.

Police reported about 7:30 p.m. that traffic on the Crosstown was at a standstill and cars were not moving on U.S. 17 north. The market area downtown became a lake.

The rain also drenched the islands and East Cooper as the front quickly moved through.

Just as some of the flooding was starting to subside a bit at 8:45 p.m, the National Weather Service reported that heavy rains were moving from the Goose Creek area into Charleston. A new torrent of rain drenched Charleston after 9 p.m.

A flash-flood warning for Berkeley, Charleston and Colleton counties was in effect until 11:15 p.m.
