WASHINGTON — Showers, storms and possible flooding are all in the forecast for the D.C. area on Sunday and into Monday morning.
The National Weather Service has issued a flash flood watch for parts of the D.C. area that will be in effect until 5 a.m. on Monday.
A flash flood watch means that conditions may develop that lead to flash flooding.

The weather service said multiple rounds of showers and thunderstorms are expected on Sunday afternoon into Sunday night that could produce 1 to 3 inches of rain on average.
Some areas might see higher amounts.
“Flash flooding is definitely a possibility,” said Storm Team 4 meteorologist Lauryn Ricketts. “We will have to closely monitor the flood threat for the second half of your Sunday.”
And in Howard County, where flooding devastated Ellicott City weeks ago, officials are taking proper precautions ahead of the heavy rain and lightning expected in the county around 4 p.m. Howard County officials have paused cleanup efforts and credentialing.
