Coastal flood advisory for Long Island Monday night into Tuesday

Coastal flooding is possible across multiple high tide cycles early this week, the National Weather Service said Monday.

A coastal flood advisory is in effect from 7 p.m. Monday to 10 a.m. Tuesday for the Island's South Shore bays and from 10 p.m. Monday to 2 p.m. Tuesday for the Long Island Sound's Nassau County shore, the weather service said.

That means that the combination of onshore winds and tides can lead to flooding of vulnerable roads and or basements, the service said.

"Water levels may also touch minor coastal flood thresholds with the high tide cycle," Monday night for Suffolk's north and south shores, the service said.

"Later high tide cycles Tuesday into Tuesday night may see similar or slightly higher water levels."
