Amateur Radio station WX4NHC is located at the National Hurricane Center (NHC) in Miami, Florida. The station has been totally assembled from donated equipment and is operated by an organized group of volunteer amateur radio operators since 1980. Read about its history.
WX4NHC activates whenever a hurricane is within 300 miles of landfall in the areas of the western Atlantic, the Caribbean or the eastern Pacific. The team of operators also provides emergency backup communications from NHC to NWS Offices and other agencies in case of local landfall. The NHC operators work in conjunction with the Hurricane Watch Net, VoIP WX-Talk Hurricane Net and other volunteer networks to collect real-time surface reports for the NHC hurricane specialists via amateur radio using many modes such as HF and VHF/UHF voice, VoIP (Voice over Internet Protocol) systems, EchoLink and IRLP, and Automatic Packet Reporting System (APRS). Input also comes from two non-amateur volunteer weather observer networks–ON-NHC (Observers Network), and CWOP (Citizens Weather Observers Program), using on-line reporting, email and fax. WX4NHC also relays hurricane advisories via the amateur radio nets to the hurricane affected areas and governmental agencies when conventional means of communications have been interrupted.
Observers’ surface reports provide the forecasters with supplemental weather and damage data that are not normally available to them and are frequently incorporated into their advisories as they provide a human perspective and eyewitness accounts of what people are experiencing during a hurricane. The WX4NHC team has been nationally recognized for its volunteer international humanitarian efforts by the National Hurricane Conference and the South Florida Hurricane Conference.
