Remain in the center of your home, in a closet or bathroom without windows. Stay away from flood waters. Do not try to cross a flooded road, turn around instead. If waters are rising rapidly around you, leave your car and climb to higher ground. The waves may look inviting, but don't be fooled.
Hurricanes produce monster rip tides which are blamed for the deaths of many swimmers each year.
Swim in a diagonal angle back to the beach at a comfortable pace. The tide may draw you out further than you are used to, but it will eventually let go and you'll need all your strength to swim back in.
