Beginning this hurricane season, NWS offices are going to use the text product EWW, Extreme Wind Warning, for eyewall situations. For the past several seasons, the product TOR was used for this purpose, and I'm sure the regulars here are familiar with all the debate over this particular use of the TOR product.
EWW issuances are supposed to be reserved for cases where the tropical cyclone is a Category 3 or greater and sustained tropical cyclone surface winds of 100 kt/115 mph or greater are occurring or expected to occur within one hour. Valid times of the EWWs (for a given county/parish) in most cases should not exceed 2 hours, but in rare cases can be for as long as 3 hours. The EWW cannot be reissued or extended for the same county/parish.
Note that I said the text product will be EWW. On NOAA Weather Radio and the Emergency Alert System, the code TOR will continue to be used until the FCC grants a new EAS code. (The NWR software at the WFO will do the conversion from the text product EWW to the NWR/EAS product TOR.)
