Hurricane Matthew is currently crossing the Caribbean heading towards Jamaica, Haiti and Cuba. http://www.hwn.org/data/nhcat4.html shows the storms predicted path.
The American Hurricane Watch Net is operating 14.325 MHz by day and 7.268 MHz as the storm passes through their area of interest.
Arnie Coro CO2KK reports that Cuba’s National Emergency Net will operate on the following frequencies;
daytime primary 7110, secondary 7120, also on lower frequencies we will have provincial nets on 7045, 7080 and possibly other frequencies.
Night time primary 3740 , secondary 3720
Their main emergency station is CO9DCN at the Cuban National Civil Defense Headquarters in Havana, under the supervision of CO2JC Doctor Carlos Alberto SantaMaria, and will be operational all along the event and the expected recovery phase.
Volunteer operators are moving to specific locations in Cuba that are known from past storms to become isolated due to rivers overflowing , roads blocked etc.
As always, amateurs are requested to listen carefully before operating on frequencies which may be in use for emergency communications and avoid interference.
