Maryland weather: As rain pours down, flooding causes road closures

The Baltimore Sun

The National Weather Service issued several flood warnings for the area Sunday night, as more rain poured down on the region.

Up to 2 inches of rain had already fallen by 6 p.m., with more on the way, according to the National Weather Service.

The flood warnings were issued for parts of Baltimore city and county, as well as for Howard and Anne Arundel counties, before being lifted around 11:45 p.m. Sunday.

By Sunday evening, flooding had already closed 32 roads in Howard County, mostly in the western and southern portions of the county. Near the Howard County/ Carroll County border, Mariottsville Road was closed, according to the Sykesville Fire Department. The National Weather Service said stream gauges along the Patapsco River at Catonsville and Elkridge indicated imminent flooding there.

The following locations were singled out for potential flooding by the National Weather Service: Baltimore, Columbia, Severn, Pikesville, Middle River, Elkridge, Riviera Beach, Baltimore-Washington Airport, Glen Burnie, Ellicott City, Dundalk, Towson, Catonsville, Essex, Woodlawn, Severna Park, Randallstown, Parkville, Owings Mills and Carney.

Because of ground already saturated with moisture, as well as estuaries swollen from previous rains and flooding, the new precipitation could result in more flooding.

Meteorologists advise motorists not to attempt to drive through flooded roads. Flooding causes more deaths than any other weather hazard, and nearly half of those deaths involve vehicles, according to the weather service.

The forecast led the Orioles to postpone Sunday’s game against the Yankees. The game will be made up as the 1:05 p.m. game of a split-admission doubleheader on Saturday, Aug. 25.

About half an inch of rain fell Saturday in the Baltimore area, and Ellicott City saw similar rainfall totals, National Weather Service meteorologist Kyle Pallozzi said. Up to 2 inches of rain fell in western Howard County, Pallozzi said.

This line of storms arrived less than a week after flooding devastated the historic district of Ellicott City and other areas of the Baltimore region. One person died in Ellicott City when he was swept away in floodwaters Sunday.

More than 8 inches of rain fell during May at Baltimore-Washington International Thurgood Marshall Airport, the region’s point of record. It was the region’s wettest month in nearly three years, and its third-wettest May on record.

But after all that rain, “the next few days will be considerably drier and sunnier for Baltimore,” said Ray Martin, a meteorologist with the National Weather Service.

It will still be considerably cooler than normal for this time of year, according to Martin, thanks to a “relatively Canadian air mass over us the next few days.”

The highs throughout the week are only in the 70s.
