High tides are expected in Palm Beach County through Friday night from the supermoon.
When the moon is full, there is the most concern for flooding.
During a full moon, the moon is on the opposite side of the Earth from the sun, causing an opposing gravitational pull and the most extreme tides.
The tides can sometimes reach about 2 feet higher than they do during other parts of the month. Coastal communities in Palm Beach County are now under a Flood Advisory through Wednesday.
Along Marine Way in Delray Beach, homes have seen flooding before during similar events. It was moderate Sunday, but there is a chance it could worsen this week.
