Flood advisory

* Flood Advisory for minor flooding of poor drainage areas in... south central Berkeley County in southeast South Carolina... Charleston County in southeast South Carolina... southeastern Dorchester County in southeast South Carolina... * until 830 am EDT * at 658 am EDT... National Weather Service Doppler radar indicated heavy rain occurring near Adams Run... or about 12 miles north of Edisto Beach. The area of heavy rain was nearly stationary. Radar indicated that rainfall rates as high as 2 to 3 inch per hour. This much rainfall will be sufficient to produce significant ponding of water on roadways and flooding of poor drainage and low lying areas. * Locations in the advisory include but are not limited to... Bears Bluff... Edisto Island... Adams Run... Yonges Island... 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.
