What are the criteria for a High Wind Watch or Warning and what is the difference? According to the National Weather Service in Des Moines:
A Wind Advisory means that sustained winds of 30 mph for one hour and/or frequent gusts of at least 45 mph are occurring or expected within the next 36 hours. These winds will make it difficult to drive high-profile vehicles. Small, unsecured objects may be blown around by these winds.
A High Wind Watch means that sustained winds of 40 mph for one hour and/or frequent gusts of at least 58 mph are expected within the next 12 to 48 hours. Check to make sure all loose objects outside are secured. Plan to postpone any unnecessary driving during this time since these winds will make driving difficult, especially for high-profile vehicles. These winds may damage trees, power lines, and small structures.
A High Wind Warning means that sustained winds of 40 mph for one hour and/or frequent gusts of at least 58 mph are occurring or expected within the next 36 hours. Ensure that all objects outside are secured. Refrain from any unnecessary driving during this time since these winds will make driving very difficult, especially for high-profile vehicles.
