A Flood Watch is in effect for the Washington, D.C. metro area, including parts of Virginia and Maryland, with the potential for dangerous flash flooding through Friday evening. Strong afternoon thunderstorms are expected to bring heavy rainfall to the region, putting commuters at risk of flooded roadways, especially on Route 50 and I-495.
Areas Affected and Flooding Risk
The Flood Watch covers Washington, D.C., most of Maryland (including Prince George’s, Anne Arundel, and Montgomery counties), and parts of Northern Virginia (such as Arlington, Fairfax, and Alexandria).
The National Weather Service has warned of intense rainfall rates that could reach 1 inch per hour, with localized totals of 2 to 3 inches possible. This heavy rain may lead to flooding in areas with poor drainage, creeks, and underpasses.
Roadways such as Route 50 and I-495 could be especially affected, making Friday’s commute difficult and dangerous. With the heavy rain expected, areas that typically struggle with drainage could experience water pooling on roads. Drivers are urged to stay alert for flash floods and avoid traveling through flooded areas.
Weather and Storm Conditions
In addition to heavy rain, the thunderstorms may come with gusty winds of up to 25 mph and occasional lightning. The weather is expected to intensify through the afternoon and evening hours. While winds will shift direction overnight, providing some relief, the ground will remain saturated, potentially causing continued flooding issues into the night.
Safety Precautions for Drivers
If you encounter a flooded road, remember the simple but vital advice: “Turn Around, Don’t Drown.” The National Weather Service strongly advises limiting travel during the Flood Watch and checking drains around homes to prevent water backups.
Weekend Outlook
Looking ahead, the weather will improve after Friday, with skies clearing by Friday night. A warm weekend is in store, with Saturday reaching a high of 93°F under partly cloudy skies. Sunday will be even hotter, with temperatures soaring to 98°F, making it the hottest day of the week. Monday will remain mostly sunny, with temperatures hitting 99°F.
Residents of Washington, D.C., Maryland, and Northern Virginia should be prepared for flash flooding on Friday afternoon and evening, especially during the commute. Stay weather-aware and follow all safety guidelines to avoid dangerous conditions on the roads. The weather will calm down by Friday night, with a warm and dry weekend ahead.
