Frederick, MD – Flash flooding is possible Thursday afternoon through late Thursday night across parts of Maryland, Virginia, and West Virginia, as rounds of heavy thunderstorms threaten to drop up to four inches of rain in some areas.
According to the National Weather Service, a Flood Watch covers Washington County in Maryland, much of Northern and Central Virginia—including Shenandoah, Culpeper, Stafford, Spotsylvania, and King George counties—and the panhandle of West Virginia, where Berkeley and Jefferson counties are at risk. The watch begins at 2 p.m. Thursday and continues into the early morning hours Friday, with storms likely to bring rainfall rates of one to two inches in just 30 minutes.
Officials warn that excessive runoff could flood creeks, rivers, and low-lying roads, especially in poor drainage and urban neighborhoods. Major routes such as US-340, I-81, and secondary highways in these counties may see water over the roadway, leading to hazardous travel and potential road closures. Residents are urged to avoid driving through standing water, charge mobile devices, and prepare for possible rapid evacuations if flash flood warnings are issued.
With the risk of multiple thunderstorm rounds, flooding could develop quickly in vulnerable areas. The Flood Watch remains in effect until 2 a.m. Friday, and additional warnings may be issued if conditions worsen. Stay alert for updates and be prepared to act if a Flash Flood Warning is issued.
