YOU SHOULD MONITOR LATER FORECASTS AND BE PREPARED TO TAKE ACTION SHOULD FLASH FLOOD WARNINGS BE ISSUED.
Flash flooding does occur in Arlington, but it usually doesn’t prompt dramatic water rescues that you might see on the news in Fairfax County or elsewhere. Frequently flooded areas in Arlington include a low-lying section of Route 110 and the trails along Four Mile Run.
It looks like heavy rain and storms impact the area later tonight. pic.twitter.com/gcuRFCyagw
