Flash Flood Warning Issued for St. Marys County, Maryland
Residents of St. Marys County, Maryland should take immediate precautions after the National Weather Service in Sterling, Virginia issued a Flash Flood Warning.

Flash flooding can develop within minutes during periods of intense rainfall. Roads, creeks, streams, neighborhoods, and other flood-prone locations may quickly become inundated.
Areas Impacted
The warning includes portions of East Central St. Marys County, including communities such as:

Radar Indicates Flash Flood Threat
According to the National Weather Service, this warning is radar indicated, meaning weather radar has detected rainfall rates capable of producing flash flooding. Even if flooding is not immediately visible, conditions can deteriorate quickly as runoff overwhelms drainage systems.
