Coastal Flood Advisory
Statement as of 5:23 AM EDT on August 31, 2015

The National Weather Service in Charleston has issued a

* Flood Advisory for minor flooding for poor drainage areas for... Charleston County in southeastern South Carolina... Berkeley County in southeastern South Carolina... Dorchester County in southeastern South Carolina...

* until 645 am EDT

* at 520 am EDT...Doppler radar indicated thunderstorms with very heavy rain moving across the Charleston tri-County region. Torrential rainfall amounts occasionally exceeding 2 inches per hour will produce significant standing water on area roads during the Monday morning rush hour.

* Some locations that will experience flooding include... Charleston...North Charleston...Mount Pleasant...Summerville... Goose Creek...Hanahan...Middleton place and downtown Charleston.

An additional 1 to 3 inches of rain is expected over the area through early morning..and locally greater amounts are possible. Minor flooding of low lying and poor drainage areas is likely.

Precautionary/preparedness actions...

This heavy rainfall will result in significant ponding of water on area roads and in low spots. Slow down to reduce the risk of hydroplaning. If water covers the entire roadway or is flowing...find another Route. The water is probably much deeper than it appears and only one foot of water can stall a vehicle. When encountering flooded roads make the smart choice...turn around...dont drown.

Heavy rain in downtown Charleston will result in nuisance flooding of low-lying areas. Areas most prone to flooding include the Market... Crosstown...East Bay street...and Morrison drive. Slow down when traveling...allowing extra distance between you and the vehicle ahead...and do not drive into water of unknown depth.

If torrential rainfall persists...a Flash Flood Warning could be issued.
