A minor coastal flood advisory is in effect for the western shore of the Chesapeake Bay through Thursday afternoon, according to the National Weather Service.
The advisory continues through 2 p.m., according to the weather service's Sterling, Va., office, with water levels as much as a foot and a half higher, said meteorologist Bryan Jackson.
High tides are expected to hit the Baltimore area after noon today, he said.
"It's pretty common for the cooler seasons" to have coastal flood advisories, which can cause some problems for sensitive areas, he said.
It also looks like snow is still a possibility this weekend.
The hazardous weather outlook includes a chance of a light accumulation of snow late Saturday night into Sunday morning, Jackson said.
Temperatures will remain below normal for the next few days, he said. They were about 10 degrees below normal today, he said.
"We're expecting a lot of Canadian air," Jackson said.
