As Hurricane Ian’s eyewall approaches land and the threat for extreme wind is expected inland, the National Weather Service will issue an Extreme Wind Warning (EWW).
The EWW product is a text product produced by National Weather Service (NWS) offices.
The following criteria is used for the issuance of extreme wind warnings, according to NWS.
- Imminent onset of, or occurring, tropical cyclone-related sustained surface winds, greater than or equal to 100 knots (115 mph).
- Extreme tropical cyclone winds are expected to occur within a WFO’s county warning area within an hour.
In addition, Extreme Wind Warnings will:
- Be issued for the smallest geographic area possible, encompassing the extreme wind conditions and use valid times of two hours or less.
- Not be reissued for the same location (if conditions persist, we will follow-up information or updates will be provided within Severe Weather Statements).
The EWW will alarm the wireless emergency alert (WEA) and NOAA Weather Radio and provide people with a heightened, short-fused warning of impending wind of 115 mph or greater.
“The last time we issued the EWW from this office was for Hurricane Irma in September 2017,” said the NWS.
