Flash Flood Warning for entire metro region

By Jason Samenow

* Outside now? Radar, temperatures & more: Weather Wall *

(originally posted at 5:20 a.m., updated at 6:20 and 6:50 a.m.)

Torrential rains have prompted the National Weather Service to issue a Flash Flooding Warning for the entire metro region until 10:45 a.m. this morning. Excerpt:

* AT 442 AM EDT...HEAVY RAIN HAS BEEN FALLING OVER THE AREA FOR THE PAST THREE HOURS...AND WILL CONTINUE TO FALL FOR THE NEXT FEW HOURS. STREAMS AND SMALL RIVERS ARE RISING QUICKLY AND FLASH FLOODING IS EXPECTED TO WORSEN DURING THE EARLY MORNING HOURS.

Doppler radar already suggests 1-2+" has fallen in the metro region - highest amounts southwest of the District. An additional 1-3" or more is possible today.

New data suggests the moderate to heavy rain could continue into the afternoon or possibly later - so the flood threat may persist for much of the day.

Remember: never try to cross a flooded roadway. Turn around. Don't drown.

The tornado watch - which means environmental conditions *could* (but not necessarily) support tornadic development - is in effect until 1 p.m. The highest risk of tornadoes is east of the Bay, although warnings for doppler radar indicated tornadoes were issued for parts of Anne Arundel and Calvert county at 3:57 a.m, and parts of St. Mary's and Calvert county at 6:20 a.m. and have since expired. We have not heard about any confirmed tornado sightings or damage reports.
