Flood watch across much of Maryland after turbulent weekend weather

Marylanders should expect more stormy weather this week, with possible flash flooding.

The National Weather Service issued a flood watch for much of Central Maryland, including Baltimore City and Anne Arundel, Carroll, Harford, Howard, Montgomery, Prince George’s and Baltimore counties. The watch goes into effect Monday at 4 p.m. through the evening.

A heat wave that settled over the region is mixing with cooler temperatures from the northeast and forming powerful storm systems, said Chris Strong, a meteorologist for the weather service’s Baltimore/Washington office. Temperatures will be in the upper 80s through Wednesday, with some scattered thunderstorms Monday evening and Tuesday.

“There’s a potential for a lot of rain to fall pretty quickly, so people should be cautious for flooding later on today,” Strong said.

A different storm system over the Fourth of July weekend knocked down trees across parts of Central Maryland. The storm also damaged Baltimore Gas and Electric equipment, according to a news release, and more than 70,000 people lost power.

As of Monday morning, more than 29,000 people were without power, according to BGE’s outage map.

The latest storms follow scorching temperatures across the state during the Fourth of July holiday. The temperature in downtown Baltimore broke a record at 104 degrees on Saturday. The previous record was 101 degrees in 2002.
