1:10 p.m.: Relentless rains continue at rates of more than an inch per hour in some places. The heaviest rain is currently along and to the west of I-95. 1 p.m. totals include 2.93" at National, 3.45" at Dulles and 1.57" at BWI. But some spots are already reporting 4-6" of rain. Sustained winds have been anywhere from 15-30 mph in the metro area, with wind gusts as high as 40-50 mph. Winds may pick up just a bit more as the storm center passes to the southeast over the next couple hours.
Between 4 and 7 p.m. we should start to see the rain moving out of the area from southwest to northeast. In the meantime, scattered reports of flooded roadways have been coming in. Never, ever drive through a flooded road.
Keep reading for earlier updates. See our earlier post for a storm timeline, rainfall potential map, wind assessment and frequently asked questions. Our rainfall forecast appears to have been underdone.
12 p.m.: The rain totals from Tropical Storm Hanna are rapidly mounting as the storm races towards the Delmarva Peninsula. Locations along and between I-95 and Rt. 29 have generally received two to as much as 6 inches of rain from Hanna. Several more inches of rain are possible.
Winds have not been consistently strong, but have tended to come in bursts in some of the heavier rain bands. 35-45 mph peak gusts have been common, with the strongest gusts east of I-95. For example, Annapolis recorded a 47 mph gust last hour.
The height of this storm should occur over the next four to six hours. This evening, wind and rain will gradually subside.
