Hurricanes are severe tropical storms that form in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico and Eastern Pacific Ocean.
Typhoons are mature tropical cyclones that develop in the western part of the North Pacific Ocean.
To prepare for a hurricane or typhoon, stock up on emergency supplies. Learn about your local emergency plans, warning signals, and evacuation routes. Be prepared to drive 20-50 miles inland to reach safety. If there is standing water or downed power lines, turn off the electricity. If you evacuate, turn off the electricity, gas and water, and take important papers and prescription drugs with you. Continue to monitor storm advisories and tell someone outside of the storm area where you are going.
