Flood Watch in effect for Arlington and most of N. Va.

Arlington — along with D.C., Alexandria, Fairfax County and most of the rest of Northern Virginia — is under a Flood Watch today.

The watch takes effect at 2 p.m. and will remain in effect into the evening hours as slow-moving storms roll into the area.

The combination of slow storm movement and the potential for training — a series of downpours focused on a specific west-to-east area — raises the possibility of flooding, forecasters say.

More from the National Weather Service:
