How Accurate Warnings?
Widespread winds of this nature are typically well forecast and warned for.

 

  • The NWS issues High Wind Warnings for exceptionally windy days where the winds (not storm related, but the general winds) are expected to cause damage (>60 mph).
  • Have a plan to:
    • Secure your location from damaging wind gusts.
    • Shelter in a suitable structure
    • Note that large branches and trees are at risk for coming down. Is that a threat in your location? How do you keep people out of harm’s way?
