The National Weather Service issued coastal flood warnings for many parts of Maryland until 8 a.m. Wednesday.
The affected areas are southern Baltimore County and Harford, Anne Arundel, Calvert, Charles and St. Mary's counties.
Baltimore and Harford Counties should expect high tide levels 2 feet above normal. The other areas are expected to see levels 1 to 2 feet higher than usual.
The tides will likely bring inundation of shoreline areas and large waves at high tide could make flooding worse, according to the weather service.
