A few showers are possible Tuesday morning as the front pushes out of Palm Beach County. Cloudy skies linger the rest of the day. Afternoon highs on Tuesday will be nearly 20 degrees cooler than Monday, topping out mainly in the 60s.

Boaters should also be cautious, as hazardous marine conditions are expected with building seas and strong winds. A small craft advisory has been issued for our coastal waters through Tuesday. Also, beach goers and spring breakers will have to deal with rip currents. It's recommended to only swim near lifeguards.
