The National Weather Service issued a flood watch Wednesday for the D.C. area, beginning at 3 p.m. and extending into the early evening. They have also issued a wind advisory through 6 a.m. Thursday.
The storm could bring heavy rain and strong gusts of wind to the area, according to the Washington Post's Capital Weather Gang, with the toughest conditions between 3 and 8 p.m. Stormy weather is likely to continue into the evening, slowing down after midnight. The storm front will also bring wind and colder temperatures compared to yesterday and today's spring-like conditions.
Though the storm is not expected to be severe, it could lead to scattered power outages, according to the Jason Samenow, weather editor at the Washington Post. The storm could also cause flooding. However, the severity of the outages will not compare to last year's devastating derecho.
"I wouldn't be surprised to see some power outages, but I don't think this will be a widespread event," Samenow said. "Of course, adding a little bit of complication is that this may be coming through during rush hour. Folks may want to plan for that and allow some extra time, just wait for this to come through before heading out or try to beat it before it comes in."
These conditions are part of a "line" of storms -- showers, thunder, heavy winds -- plowing through the eastern United States, including Pennsylvania.
