Up to three inches of rain have already fallen across the Charleston peninsula and surrounding areas. At 640 PM, Doppler radar indicated clusters of strong thunderstorms upstream of the Charleston area. These storms are expected to track across the warned area, producing torrential downpours. In addition, high tide will peak at 645 PM, with Tide Water remaining high through 730 PM. Flood waters will deepen over flooded streets, with some areas seeing flood waters a few feet deep. Many roads will be impassible with flooding of some homes and businesses likely through 9 PM.
Some locations that will experience flooding include... Charleston, North Charleston, Mount Pleasant, downtown Charleston, west Ashley, and Charles Towne Landing.
