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:
…FLOOD WATCH REMAINS IN EFFECT FROM 2 PM EDT THIS AFTERNOON THROUGH THIS EVENING…
* WHAT…FLASH FLOODING CAUSED BY EXCESSIVE RAINFALL CONTINUES TO BE POSSIBLE. […]
* IMPACTS…EXCESSIVE RUNOFF MAY RESULT IN FLOODING OF RIVERS, CREEKS, STREAMS, AND OTHER LOW-LYING AND FLOOD-PRONE LOCATIONS.

– SHOWERS AND NUMEROUS THUNDERSTORMS ARE EXPECTED THIS AFTERNOON INTO THIS EVENING. RAINFALL AMOUNTS WILL AVERAGE AROUND 1 TO 1.5 INCHES ACROSS THE AREA, BUT LOCALLY HIGHER AMOUNTS OF 2 TO 4 INCHES ARE LIKELY AND MUCH OF THAT MAY FALL IN A ONE TO TWO HOUR TIMEFRAME.
