If you're heading to the beach today, watch out for rip currents. 

An advisory has been extended for Palm Beach County because of weather conditions.  The advisory runs to the south, through Broward and Miami-Dade Counties. 

You'll notice the red flags along beaches, warning about rough conditions. 

Lifeguards say if you get caught in a rip current, remain calm and swim parallel to shore until you can escape the current and swim back to the beach.
