Severe weather in Washington, D.C. region

Overview

The Washington, D.C. metropolitan region experienced a period of volatile weather starting with a slow-moving storm system in early August. This initial system brought repeated showers, thunderstorms, and heavy rainfall, creating risks of flash flooding and wind-related damage to local gardens and infrastructure.

By mid-August, the weather pattern shifted to include extreme heat alongside severe thunderstorms. Heat index values reached or exceeded 100 degrees, leading Mayor Muriel Bowser to activate a heat alert. During this period, severe thunderstorm warnings were issued across the District of Columbia, Maryland, and Virginia, with threats of large hail and wind gusts between 60 and 80 mph. Flash flood warnings were issued for specific counties in Maryland, and a brief tornado warning was issued for the Baltimore area before being canceled.

In late August, the region faced renewed risks of heavy rain and thunderstorms. Forecasters warned that high humidity could fuel intense downpours, potentially resulting in rainfall totals of 1 to 2 inches. This created a risk of isolated flash flooding, particularly in areas south and east of the Interstate 95 corridor and the Eastern Shore, with St. Mary’s County noted as potentially vulnerable due to recent heavy precipitation. A cold front moving through the region eventually led to drier, more comfortable conditions.

By early September, the area faced a new period of intense heat and humidity coupled with the threat of severe thunderstorms. Following severe weather earlier in the week, tens of thousands of power outages were reported across D.C., Maryland, and northern Virginia, leading to the closure of Prince George’s County Public Schools. Forecasters warned that high temperatures in the 90s could trigger further strong to severe thunderstorms, with primary concerns including damaging winds, hail, and heavy rain.
