Update at 4 p.m. — The Flood Warning has now been cancelled.
Earlier: As what remains of Hurricane Zeta drenches the region, Arlington County is now under a Flood Warning, meaning flooding is currently happening or is imminent.
“Observations show we’re crossing the 1.5″ rain total threshold throughout much of the urban corridor,” the National Weather Service said just before noon. “Flooding is going to be slow to develop but we should see increasing reports of it this afternoon.”
Flooding has already been reported west of Arlington in Fairfax County, along Wolftrap Creek and Accotink Creek. The warning is in effect until 5:30 p.m.
In addition to heavy rain, strong winds are expected between roughly 5-8 p.m. this evening as the center of the storm passes the region.
