Updated Monday, October 27, 2025 @ 9 AM EDT (1300 UTC)<\/strong><\/em><\/p>\n ARRL thanks Carlos Alberto Santamar\u00eda Gonz\u00e1lez, CO2JC, for information included in this update. Forecasts indicate Hurricane Melissa will affect Cuba, especially its eastern region.<\/p>\n Starting at noon today (Monday, October 27), the National Emergency Network of the Cuban Radio Amateur Federation (REN-FRC in Spanish) will be activated through station CO9DCN, from the National Civil Defense Staff.<\/p>\n Several amateur radio emergency networks have been active in the eastern part of the country for more than 72 hours, according to personal communications we have received from the presidents of the provincial branches of Las Tunas, Granma, and Santiago de Cuba.<\/p>\n In addition to the frequencies established in each municipality for communications on the 2m band, the following national emergency frequencies established in our regulations will be in use:<\/p>\n 40m band: 7110 and 7120 kHz. For this reason, we ask all Cuban and regional radio amateurs, to protect these frequencies, remain listening only, and refrain from transmitting on them unrelated to the emergency.<\/p>\n Cuban radio amateurs, despite the technical and battery difficulties we face, will once again emphasize the importance of radio communications in emergency situations.<\/p>\n For everyone, always, the main recommendation will be to protect their lives and only then maintain communications.<\/p>\n Carlos Alberto Santamar\u00eda Gonz\u00e1lez, CO2JC Updated Sunday, October 26, 2025 @ 3:15 PM EDT (1915 UTC)<\/b><\/em><\/p>\n ARRL thanks\u00a0WX4NHC, the Amateur Radio Station at the National Hurricane Center, and\u00a0the Hurricane Watch Net (<\/em>www.hwn.org<\/em>) for this update.<\/em><\/p>\n Hurricane Melissa Update and Hurricane Watch Nets Ready for Activation<\/b><\/p>\n Hurricane Melissa is expected to move near or over Jamaica on Tuesday, across southeastern Cuba Tuesday night, and across the southeastern Bahamas on Wednesday.\u00a0Melissa is expected to be a powerful major hurricane when making landfall in Jamaica and Cuba.<\/p>\n WX4NHC<\/strong><\/span>, the Amateur Radio Station at the National Hurricane Center, will be activated on Monday, October 27 at 7 PM\u00a0EDT for Hurricane Melissa forecast track affecting Jamaica, Cuba, and the Bahamas. The station\u00a0expects to be active until Wednesday. The exact timing may vary depending on the Hurricane\u2019s track and speed. WX4NHC will be on the air on the Hurricane Watch Net frequency 14.325 MHz most of the time and 7.268 MHz depending on propagation;\u00a0 WX4NHC will be on the VoIP Hurricane Net\u00a0<\/span>(IRLP node 9219 \/ EchoLink WX-TALK Conference node 7203);\u00a0<\/p>\n WX4NHC will be monitoring WinLink and online reports;\u00a0WX4NHC@winlink.org use \/\/WL2K<\/b> in email subject.

The storm is nearly stationary, drifting west at approximately 3 mph, and is forecast to intensify to a\u00a0Category 5 hurricane\u00a0within 48 hours. Heavy rainfall is already affecting southern Hispaniola, causing life-threatening flooding and mudslides. Similar conditions are expected in Jamaica in the coming days.<\/p>\n Activation Status<\/b><\/p>\n Melissa is now a hurricane and well within our 300-mile activation criteria. For now, hurricane-force winds are forecast to remain offshore until Tuesday evening.<\/p>\n Normally, a Net activation is straightforward \u2014 we set a start time and an approximate end time.\u00a0Melissa is not one of those storms.<\/b>\u00a0The closest comparisons are\u00a0Matthew (2016)<\/b>\u00a0and\u00a0Dorian (2019)<\/b>\u00a0\u2014 both stalled, high-intensity hurricanes that required flexible, around-the-clock operations for days.<\/p>\n Since hurricane-force winds remain offshore and the storm is expected to parallel the island of Jamaica, our\u00a0tentative plan<\/b>\u00a0is to activate\u00a0Monday morning at 8:00 AM EDT (1200 UTC)<\/b>\u00a0on\u00a014.325 MHz<\/b>, with 40-meter operations beginning at\u00a07:00 PM EDT (2300 UTC)<\/b>. Depending on propagation and storm evolution, both frequencies may operate simultaneously.\u00a0If the storm changes course toward land on Sunday, HWN will activate immediately.<\/b><\/p>\n Operational Frequencies<\/b><\/p>\n As a reminder, HWN also provides\u00a0Health and Welfare Traffic,<\/b>\u00a0and backup communications for\u00a0Emergency Operations Centers, Red Cross shelters, and other agencies<\/b>, sharing critical damage assessment information as requested.<\/b><\/p>\n Updates and changes to operational plans will be posted on\u00a0www.hwn.org<\/b>\u00a0and HWN social media channels.<\/p>\n HWN thanks all amateur radio operators and nets for maintaining clear frequencies, enabling timely communication to those in harm\u2019s way.<\/p>\n Updated 10\/24\/2025<\/strong><\/em><\/p>\n Important Notice: Emergency Frequencies \u2014 Keep Clear During Contest Weekend<\/p>\n As the Caribbean faces potential hurricane impacts,\u00a0IARU Region 2<\/strong>\u00a0has activated\u00a0emergency nets<\/strong>\u00a0on the following frequencies:<\/p>\n If the\u00a0Hurricane Watch Net (HWN)<\/strong>\u00a0activates, they will be operating on:<\/p>\n The\u00a0amateur radio station at the\u00a0National Hurricane Center, WX4NHC,\u00a0<\/strong>will also be monitoring the HWN frequencies for real-time weather and situation reports.<\/p>\n This weekend coincides with the\u00a0CQ World Wide SSB Contest<\/strong>, one of the busiest times on the bands.\u00a0All operators are urged to exercise extra vigilance<\/strong>\u00a0and\u00a0avoid transmitting on or near these emergency and hurricane watch frequencies.<\/strong><\/p>\n These nets are providing critical communication links supporting the\u00a0Caribbean Islands and affected regions<\/strong>. Please ensure they have clear and reliable access to designated frequencies.<\/p>\n In summary:<\/strong><\/p>\n Original news story, October 24, 2025:<\/strong><\/em><\/p>\n All eyes and ears are on Tropical Storm Melissa, now in the Caribbean Sea. As of 6:30:00 AM EDT on Thursday October 23, 2025, the National Weather Service Hurricane Center in Miami, Florida reports that Melissa is crawling over the central Caribbean sea and is expected to bring heavy rains and life-threatening flooding\u00a0 to portions of Hispaniola and Jamaica over the weekend.<\/p>\n A hurricane watch remains in effect for the southwestern peninsula of Haiti, from the border with the Dominican Republic to Port-Au-Prince. A tropical storm watch is in effect for Jamaica.<\/p>\n Currently melissa is located about 240 miles SSE Kingston Jamaica and about 300 miles from the SW Port of Au Prince Haiti. Maximum sustained winds are 50 miles per hour (mph) and the present movement is WNW at 3 mph.<\/p>\n \u201cMelissa is definitely going to need to be watched. If it makes it into the Gulf, it could be a big problem,\u201d said ARRL Director of Emergency Management Josh Johnston, KE5MHV.<\/p>\n The Hurricane Watch Net is carefully monitoring the storm\u2019s development. While earlier appraisals weren\u2019t certain of its direction, most of the projections now expect a turn to the northwest then north over the next few days. This puts Haiti and Jamaica in its sights later this week. Tropical storm-force winds extend to 115 miles from the center of the storm.\u00a0<\/p>\n According to the National Hurricane Center\u2019s latest bulletin, hurricane conditions in Haiti might begin on Thursday, then in Jamaica Thursday and Friday. The greatest threat is heavy rainfall in Haiti and Dominican Republic with 5 to 10 inches expected through Friday.\u00a0<\/p>\n ARRL News will have any further updates as the storm progresses.<\/p>\n<\/p><\/div>\n
