Flood watches remain in effect. Click on your county in the list above to view the latest information.
WASHINGTON POST: RECORD RAIN WREAKS HAVOC FOR MORNING COMMUTE. MUDSLIDE CLOSES PART OF BELTWAY EARLY THIS MORNING. METRO DELAYS--SOME STATION CLOSINGS. UNSCHEDULED LEAVE FOR FEDERAL EMPLOYEES.
BEWARE OF HIGH STANDING WATER ON ROADWAYS. TURN AROUND, DON'T DROWN.
Widespread flash flooding occurred Sunday night in DC as well as surrounding suburbs. Particularly hard hit were areas of Montgomery County which received upwards of 6". Numerous reports of stranded vehicles, road closures and water rescues were documented. Conditions remain favorable for more episodes of flooding rain through Tuesday, and rainfall totals will likely break records in some areas.
Periods of heavy rain, with some breaks A stalled front to our west coupled with an area of slow moving low pressure to the south is promoting uninhibited moist, southerly flow. Accordingly, the potential remains for flooding rain, with another 2-4" possible by Tuesday morning.
As was the case yesterday, due to the somewhat random nature in which these storms develop, some areas may receive less than this while some may receive more. And some areas may well experience significant periods of time with no rain and even some sunshine. High temperatures should be near 80, with lots of humidity. Rain coverage/intensity is likely to be greatest during the late afternoon and evening.
Overnight, the potential for heavy rain remains for much of the area. Pinpointing who gets exactly what is difficult, but everyone should be aware of the possibility of dangerous, flash flooding.
Pictured: The NAM computer model predicts 3-5" (red color) of rain through Wednesday morning for much of the area. Some areas are likely to experience locally heavier amounts.
Flood potential continues. Another wave of tropical moisture is likely to move northward through the area, potentially dropping 2-4" more rain, with locally higher amounts. Some areas may experience 5-day rainfall totals of over one foot. High temperatures Tuesday will likely be between 75-80. Sometime late Tuesday night, the potential for flooding rain may diminish, as high pressure begins to build in from the west.
(Note: the usual 7-day forecast has been pre-empted for coverage of this flood event).
