Act now

If authorities have issued a tropical cyclone/hurricane warning for your area, find safe shelter right away!

  • Evacuate if told to do so.
  • Take refuge in a designated storm shelter or an interior room for high winds.
  • Listen for emergency information and alerts.
  • Only use generators outdoors and away from windows.
  • Turn Around, Don’t Drown! Do not walk, swim, or drive through flood waters.

Plan ahead

Live in or plan to visit an area at-risk of tropical cyclones/hurricanes?

  • Know your area’s risk of tropical cyclones/hurricanes.
  • Sign up for your community’s warning system.
  • If you are at risk for flash flooding, watch for warning signs such as heavy rain.
  • Practice going to a safe shelter for high winds. The next best protection is a small, interior, windowless room in a sturdy building on the lowest level that is not subject to flooding.
  • Based on your location and community plans, make your own plans for evacuation or sheltering in place.
  • Become familiar with your evacuation zone, the evacuation route, and shelter locations.
  • Gather needed supplies for at least three days (at least two weeks if in Hawaii or other remote area). Keep in mind each person’s specific needs, including medication. Don’t forget the needs of pets.
  • Keep important documents in a safe place or create password-protected digital copies.
  • Protect your property. Declutter drains and gutters. Consider hurricane shutters.
