The National Weather Service issued a flash flood watch across the Baltimore region Tuesday afternoon, with more heavy rains forecast.

The watch includes Baltimore City, southern Baltimore County, and Harford, Howard and Anne Arundel counties. As much as 1-3 inches of rain is possible, according to the advisory, which is effective through 6 p.m.


The rain is expected to fall on ground that is already saturated with recent heavy rains, and streams and rivers may also remain somewhat swollen. At Baltimore-Washington International Thurgood Marshall Airport, 6.26 inches of rain have fallen so far in June, more than 4 inches above normal.

Heavy showers were moving through Southern Maryland early Tuesday, prompting a flash flood warning that included southern Anne Arundel up to the Annapolis area.


Record June rainfall for Baltimore is just shy of 10 inches.

Highs Tuesday were forecast in the upper 80s with high humidity, according to the weather service.

Overnight lows were expected to be mild, in the lower- to mid-70s.

Some shower chances could linger into Wednesday morning. Beyond that, humidity and temperatures are expected to fall. Highs are forecast Wednesday through Friday around 80 degrees, with lows in the 60s and dew points in the 50s.
