As of 5:20 p.m., radar rainfall estimates showed between 1.5 inches and 2.5 inches of rain fell across the greater Charleston area since 2 p.m., the Weather Service said.
"The previous heavy rainfall resulted in multiple flooded roads and a couple of water rescues," the Weather Service said. "Based on latest reports, several roads remain closed due to lingering flood waters. Through 7 p.m., showers and thunderstorms will result in rounds of moderate rainfall."
"The arrival of the heavy downpours will overlap with this evening's high tide, resulting in significant street flooding and building flooding," the Weather Service said. "Many roads will be impassable."
