Maryland weather: Possible flooding Saturday as heavy rain returns

Rain is forecast to return to Maryland late Friday, and meteorologists warned it could bring with it flooding risks on Saturday.

The National Weather Service issued a flood watch across Central Maryland for Saturday afternoon and evening.

A large area of low pressure is forecast to bring moderate rain and periods of heavy rain. A widespread 1.5-2.5 inches of rainfall is expected, and some areas could see as much as 4 inches, weather service forecasters said.

At least some drizzle reached the Baltimore region Friday evening, with periods of heavier rain expected overnight and into early Saturday morning. Rain is likely to continue into Sunday morning.

“Runoff from the rainfall may cause creeks and streams to rise out of their banks as well as the potential for flooding in urban areas,” they wrote. “Now that it is the cold season, the soil is even less capable of absorbing significant rainfall, and without active vegetation, runoff is significantly higher, so it will not take as much rain to get flooding.”

This year is already Baltimore’s wettest on record, with nearly 66 inches of rain at the region’s point of record, Baltimore-Washington International Thurgood Marshall Airport. That is more than 20 inches above normal annual rainfall totals at BWI and 4 inches above the previous record, set in 2003.
