Boating safety tips during severe weather

• Check the forecast before hitting the water. Sunny mornings may turn into dangerous afternoons, especially during monsoon season.

• Have a way to communicate. Cell phone reception is limited. Tune your marine band radio to channel 16 or 22A.

• Take a GPS on the water, so if you get stranded, you can tell emergency crews where you are.

• If you see a storm approaching, head to a sheltered cove or inlet. It’s easier to escape a storm before it hits. Boat ramps become crowded after the storm arrives.

• Get all swimmers and skiers out of the water.

• Strong winds create large waves. When waves get choppy while boating, have everyone on board put on a life jacket.

• If your boat becomes disabled during a storm, throw an anchor or empty bucket attached by a line into the water to slow drifting.

• Secure loose items under seats, in storage areas or in the center of the boat.

• Be prepared to spend the night on your boat or on shore, by packing extra food, water and blankets.

• Let someone know where you are going and when you will return.
