What actions can I take to prepare and/or stay safe?

Before the storm

  • Secure outdoor objects that could be blown over by wind (e.g, patio furniture, sports equipment, trash cans, pop-up canopies)
  • Rake leaves and other yard debris and place in green bin (to keep out of gutters and storm drains)
  • Make sure your emergency kit is up-to-date: have a flashlight, radio and spare batteries handy if the power goes out.
  • Protect homes and businesses in low-lying flood-prone areas by making sandbags.
  • Mariners / Houseboat occupants should secure vessel for severe wind and seas.
  • Sign up to receive AlertMarin emergency calls, text message or email alerts.
  • Visit for additional resources for preparing for a storm.

During the storm

  • Avoid unnecessary travel. Strong winds and wet roads make travel risky, and possible flooding may prevent you from returning home. Staying home is the safest option until the storm passes. If it’s an emergency, allow emergency responders to come to you.
  • Use extra caution when driving. If you MUST leave your home, drive carefully: slow down, keep both hands on steering wheel, turn on head lights, allow extra space between vehicles, and watch for downed tree branches, trees, and powerlines.
  • Stay away from downed power lines. Always assume a fallen power line is live and do not touch it with your hand or other object. Call 9-1-1 immediately to report the fallen line.
  • Do not walk or drive through standing water. Turn around, do not drown. If it’s an emergency, allow emergency responders to come to you.
  • Avoid the coast and beaches.
  • Mariners / Houseboats should remain in port. Strong winds and cause hazardous seas which could capsize or damage vessels.
  • Monitor for the most up-to-date weather and emergency information.


Sand, bags, and shovels are available for Fairfax residents at the Skate Park (Pavilion Parking Lot).
