The primary risks include flash flooding, damaging winds, and power outages. Areas under the flash flood warning, such as Arlington County, Alexandria, and parts of Montgomery County, are particularly vulnerable. Drivers are cautioned to avoid flooded roadways, as water depth can be deceptive, especially at night. The storms have already caused infrastructure damage, including downed trees and power lines, leading to localized outages. Residents in low-lying or flood-prone areas should remain vigilant as heavy rain continues to increase the risk of flash flooding.
