Areas of flooding will be possible with the continued chance for heavy rain through this evening.

After storms dropped multiple inches of rain last night across the D.C. area, numerous showers and storms are anticipated again through this evening. An upper-level disturbance continues to spin to the southwest of D.C., ensuring plenty of moisture from the Atlantic into the region.

With this pattern, showers and storms will also tend to steer over the same areas as they travel from south to north, creating a process we call training, as they follow one another like train cars. This may add to flooding troubles when showers and storms develop later today.

The Flash Flood Watch officially calls for one to two inches of rain in locations today, with the potential for isolated higher amounts. Over the past few days, parts of the region have received over two inches of rain, so the area is already primed. Flash Flood Guidance shows many areas only need a few inches of rain within a three hour period in order to flooding to occur. Be sure to take precautions later today while on the roads and if you encounter high water, be sure to turn around to find another route.
