Hurricane Preparedness Week: May 1st-7th

Know what to do before a hurricane hits

Posted

Hurricanes are among nature's most powerful and destructive phenomena.

On average, 12 tropical storms, six of which become hurricanes form over the Atlantic Ocean, Caribbean Sea, or the Gulf of Mexico during the hurricane season which runs from June 1st to November 30th each year.

In the Central Pacific Ocean, an average of three tropical storms, two of which become hurricanes form or move over the area during the hurricane season, which runs from June 1st to November 30th each year.

Guam, the Northern Marianas, and Micronesia experience typhoons all year round but the main season is July through November with a peak from mid-August to mid-September.

Over a typical 2-year period, the U.S. coastline is struck by an average of three hurricanes, one of which is classified as a major hurricane (winds of 111 mph or greater).

By knowing what actions to take before the hurricane season begins and a hurricane approaches, and when the storm is in your area, as well as what to do after a hurricane leaves your area, you can increase your chance of survival. 

Hurricane Hazards

While hurricanes pose the greatest threat to life and property, tropical storms and depression also can be devastating. The primary hazards from tropical cyclones (which include tropical depressions, tropical storms, and hurricanes) are storm surge flooding, inland flooding from heavy rains, destructive winds, tornadoes, and high surf and rip currents.

  • Storm surge is the abnormal rise of water generated by a storm's winds. This hazard is historically the leading cause of hurricane-related deaths in the United States. Storm surges and large battering waves can result in large loss of life and cause massive destruction along the coast.
  • Storm surges can travel several miles inland, especially along bays, rivers, and estuaries.
  • Flooding from heavy rains is the second leading cause of fatalities from landfalling tropical cyclones. Widespread torrential rains associated with these storms often cause flooding hundreds of miles inland. This flooding can persist for several days after a storm has dissipated.
  • Winds from a hurricane can destroy buildings and manufactured homes. Signs, roofing material, and other items left outside can become flying missiles during hurricanes.
  • Tornadoes can accompany landfalling tropical cyclones. These tornadoes typically occur in rain bands well away from the center of the storm.
  • Dangerous waves produced by a tropical cyclone's strong winds can pose a significant hazard to coastal residents and mariners. These waves can cause deadly rip currents, significant beach erosion, and damage to structures along the coastline, even when the storm is more than 1,000 miles offshore.

What to do BEFORE a hurricane hits

The best time to prepare for a hurricane is before hurricane season begins on June 1st. It is vital to understand your home's vulnerability to storm surges, flooding, and wind. Here is your checklist of things to do BEFORE hurricane season begins.

  • Know your zone: Do you live near the Gulf or Atlantic Coasts? Find out if you live in a hurricane evacuation area by contacting your local government/emergency management office or by checking the evacuation site website.
  • Put Together an Emergency Kit: Put together a basic emergency. Check emergency equipment, such as flashlights, generators, and storm shutters.
  • Write or review your Family Emergency Plan: Before an emergency happens, sit down with your family or close friends and decide how you will get in contact with each other, where you will go, and what you will do in an emergency. Keep a copy of this plan in your emergency supplies kit or another safe place where you can access it in the event of a disaster. Start at the Ready.Gov emergency plan webpage.
  • Review Your Insurance Policies: Review your insurance policies to ensure that you have adequate coverage for your home and personal property.
  • Understand NWS forecast products, especially the meaning of NWS watches and warnings.
  • Preparation tips for your home from the Federal Alliance for Safe Homes
