LANHAM, Md. (WNEW/AP) — A record rainfall at Baltimore-Washington International Thurgood Marshall Airport has led to flooding at the airport’s parking lots and roads throughout the D.C.-Baltimore region.

National Weather Service meteorologist Heather Sheffield said that at 5 p.m. Tuesday, 6.27 inches of rain at fallen at the airport since 8 a.m. She says that breaks a record rainfall set on Aug. 12, 1955, when 4.91 inches of rain fell. And it had not stopped raining.

BWI spokeswoman Whitney Kidd said the rain was not affecting air traffic, but there was some flooding on surrounding roads, and some parking lots had flooded.

Meanwhile, rescue crews in Montgomery and Anne Arundel counties spent hours Tuesday helping some motorists who became stuck after the heavy rains.

Anne Arundel County fire department spokesman Russ Davies says crews helped rescue at least 26 people who became stranded in their cars, apparently as a result of flash flooding Tuesday. No one was injured.

Rescue crews in Montgomery County helped more than half a dozen people who became stranded in their vehicles, according to fire department spokesman Pete Piringer.

Most of the Flash Flood Warnings and Flood Warnings in the D.C.-Baltimore area have expired, but a Flash Flood Watch remains in effect for the entire region through late Tuesday night.

Piringer says heavy rains caused localized flooding. He says officials recommend motorists don’t try to drive through moving water.

Laurel spokeswoman Audrey Barnes says there are several areas flooded in the city and numerous roads are closed.
