A flood watch is in effect throughout the Baltimore metro area from Tuesday afternoon into Wednesday morning, warning that excessive rainfall could cause flooding. A coastal flood watch is also in effect for parts of Baltimore County and Anne Arundel County.

About 2 to 4 inches of rain could fall on downtown Baltimore after noon Tuesday, bringing tides up to 5 feet above normal and potentially causing flooded roads in downtown Baltimore and Annapolis as well as yards, roads and homes in the Bowleys Quarters area around 4 a.m. Wednesday.

Harford County Public Schools will close schools and offices three hours early, and Anne Arundel County Public Schools will close two hours early Tuesday.

Baltimore County Public Schools will cancel all after-school activities, athletic games and practices. The county’s school board meeting will take place virtually.

Those picking up sandbags must show proof of residence or business ownership in Baltimore, such as a driver’s license, utility bill or business license. Users must fill and transport their sandbags.

The rain is forecast to be accompanied by steady winds reaching 20 to 25 mph Tuesday afternoon and gusts as high as 50 mph at night. A wind advisory is in effect from 3 p.m. Tuesday to 1 a.m. Wednesday, as the gusts could blow down tree limbs, causing a few power outages, and move unsecured objects.
