Meteorologists warned of flash flooding potential through Saturday morning, with chances for showers and thunderstorms until then.
A flash flood watch is in effect across Central Maryland through Saturday at 6 a.m. While downpours are expected to be somewhat scattered, they still pose flooding hazards, forecasters said.
“Given saturated soil from recent rainfall, repetitive heavy rain may result in flash flooding,” weather service meteorologists wrote.
Friday could see up to a half-inch of new rainfall, with more coming in the evening.
Heavy rain moved through some parts of the Baltimore region Wednesday night, prompting a flood warning for Baltimore City, Baltimore County and Harford County through early Thursday morning. It was then extended.
“Urban areas, locations along small streams and creeks, and poor drainage areas are most vulnerable to flash flooding,” meteorologists wrote.
Officially, about a quarter of an inch of rain fell Wednesday at Baltimore-Washington International Thurgood Marshall Airport, the region’s point of record.
July ended on Tuesday as Baltimore’s second-wettest month on record, with 16.73 inches of rainfall at BWI.
