Snow blankets Fraser Avenue in Madawaska on March 22, 2019.

Southern Maine could see significant coastal flooding and what might be the last throes of winter are expected to hit northern Maine with a snowstorm later in the week.

The National Weather Service issued a flood advisory on Tuesday that is in effect from 10 p.m. Tuesday until 3 a.m. Friday for southwest Maine and southern New Hampshire, particularly the Maine towns of York, Cumberland and Rockingham.

The weather is expected to get lively for a greater portion of the state on Thursday, as a low-pressure weather system could bring strong winds and rainfall that could create ponding on southern Maine roadways and snow to northern Maine, according to weather service offices in Gray and Caribou. Both offices issued weather advisories on Tuesday.

A significant amount of snow is expected to start falling in northern Maine on Thursday afternoon before ending on Friday morning. Meteorologists can’t yet tell what areas of the state will get hit the hardest, according to a winter weather advisory from the weather service office in Caribou. The snowfall, and melting ice and snow runoff, are expected to bring river water levels close to the top of river banks.
