Tropical Storm Melissa is nearly stationary in Caribbean on Friday, October, 24,
2025. Forecasters warn it could quickly intensify, impacting Jamaica as a
hurricane and causing catastrophic flooding and landslides Haiti and the
Dominican Republic.
The Hurricane Watch Net[1] (HWN) a group of licensed Amateur Radio Operators
trained and organized to provide essential communications support to the
National Hurricane Center during times of hurricane emergencies, is carefully
monitoring the storm's development.
Important Notice: Emergency Frequencies - Keep Clear During Contest Weekend
As the Caribbean faces potential hurricane impacts, IARU (International Amateur
Radio Union) Region 2 has activated emergency nets on the following frequencies:
o 40 meters: 7.198 MHz and 7.098 MHz
o 20 meters: 14.198 MHz
If the Hurricane Watch Net (HWN) activates, they will be operating on:
o 14.325 MHz
o 7.268 MHz
The amateur radio station at the National Hurricane Center, WX4NHC[2], will also
be monitoring the HWN frequencies for real-time weather and situation reports.
This weekend coincides with the CQ World Wide SSB Contest[3], one of the busiest
times on the ham radio bands. All operators are urged to exercise extra
vigilance and avoid transmitting on or near these emergency and hurricane watch
frequencies.
These nets are providing critical communication links supporting the Caribbean
Islands and affected regions. Please ensure they have clear and reliable access
to designated frequencies.
In summary:
o Keep clear of 7.198, 7.098, 7.268, 14.198, and 14.325 MHz
o Be aware of possible emergency or health-and-welfare traffic on nearby
frequencies
o Operate responsibly and help maintain open frequencies for those
supporting hurricane response efforts.
