The updated criteria are as follows:

High Wind Warning:

1. Sustained winds of 40 mph or greater for an hour or more, and/or gusts of 58 mph or higher.

2. Summits of Haleakala, Mauna Loa, and Mauna Kea: Sustained winds of 56 mph or greater for an hour or more, and/or gusts of 66 mph or higher.

High Wind Warning products alert the public to the potential for strong and damaging winds. Winds that reach the warning threshold are capable of doing significant damage to structures, widespread damage to vegetation, and represent a serious hazard.
