When the US Coast Guard and other stations in North America and the Caribbean broadcast high-seas and offshore weather forecasts on HF and MF, on the timelines of your cities and in your own time zone.
The US Coast Guard runs HF voice weather broadcasts from three stations: Chesapeake (NMN) in Virginia for the western North Atlantic, New Orleans (NMG) for the Gulf of Mexico and the Caribbean, and Point Reyes (NMC) in California for the eastern North Pacific. A computer-generated voice reads the high-seas and offshore forecasts and storm warnings on several frequencies at once, so boats far offshore can pick the band that propagates best. The calendar also includes the Boston NAVTEX broadcast on 6314 kHz, Bermuda Harbour Radio, CROSS Martinique for the French Antilles and the Cayman Islands Coastguard.
Coast Guard schedules are published in UTC, while the US moves its clocks on different dates from Europe and across six time zones of its own. This calendar follows the EiBi schedule and places each broadcast at its local time in each of your cities, from the Chesapeake to San Francisco to a mooring in the Caribbean.
