Heavy rains delay p.m. travels

A flash flood watch is in effect for much of the area until 10 tonight, promising a dicey commute as Washingtonians get a start on the weekend.
According to the Capital Weather Gang, 2 to 3 inches of rain are possible, with some heavier amounts in concentrated areas. Transportation agencies are already on the alert. The Maryland Transit Administration announced that its Camden Line will operate under speed restrictions due to the possibility of flash floods. Rail commuters on that line may experience delays of 20 to 30 minutes.
The Maryland Transportation Authority also announced that it would not implement two-way operations on the Chespeake Bay Bridge, due to the weather. Officials said the could change if conditions improve, but warned drives on Routes 50/301 to brace for the possibility of delays.
Drivers around the region were being urged to proceed with caution especially in areas with standing water. According to the Federal Emergency Management Agency:
• Six inches of water will reach the bottom of most passenger cars and may cause you to lose control or stall.

.• A foot of water will float many vehicles

.• Two feet of rushing water can carry away most vehicles — even SUVs and pickups.

Flooding is likely in low-lying areas and on streets with slow drainage. Additionally, flooded areas may be more difficult to identify at night, they said.

Power delays are minimal in the Washington area, with about 4,000 customers without service, according to the major utilities. However, most of the outages, more than 3,000, were concentrated in Montgomery County.

Some flight delays were being reported in the eastern portion of the country, with the longest delays affecting traffic destined for New York area airports.
