DEPUTY DIRECTOR, OCEAN PREDICTION CENTER
SUBJECT: DISCONTINUATION OF THE CONDENSED VERSIONS OF OFFSHORE
MARINE FORECAST PRODUCTS ON JANUARY 6, 2026
THE NWS’S OCEAN PREDICTION CENTER (OPC) AND NATIONAL HURRICANE
CENTER (NHC) WILL DISCONTINUE THE CONDENSED VERSIONS OF OFFSHORE
MARINE FORECAST PRODUCTS STARTING ON JANUARY 5, 2026.
THESE CONDENSED PRODUCTS ARE PROVIDED TO THE U.S. COAST GUARD
(USCG) FOR BROADCAST OVER THEIR HF RADIO TRANSMITTERS, COMMONLY
REFERRED TO AS HIGH FREQUENCY VOICE BROADCASTS (HF VOBRA) (A
LIST OF THE PRODUCTS TO BE DISCONTINUED ARE LISTED IN TABLE 1).
THE CONDENSED PRODUCTS DO NOT BROADCAST OVER NOAA WEATHER RADIO
(NWR) TRANSMITTERS, ONLY VIA HF RADIO STATIONS OPERATED BY THE
USCG. NO CHANGE IS BEING PROPOSED TO NWS MARINE FORECAST
PRODUCTS THAT ARE BROADCAST OVER NWR. NO OTHER CHANGES ARE BEING
CONSIDERED FOR THE OFFSHORE WATERS FORECASTS (OFF), HIGH SEAS
FORECAST (HSF), OR NAVTEX PRODUCTS (SEE TABLE 2 FOR A LIST OF
PRODUCTS CONTINUING).
OFF AND NAVTEX PRODUCTS PROVIDE THE SAME INFORMATION OVER THE
SAME AREA, INCLUDING WARNINGS FOR HAZARDOUS CONDITIONS LIKE
GALES, STORMS, TROPICAL STORMS, HURRICANES, AND FREEZING SPRAY.
THE FULL OFFSHORE TEXT FORECASTS WILL CONTINUE TO BE AVAILABLE
OVER THE INTERNET FROM OPC AT HTTPS://OCEAN.WEATHER.GOV, AND
FROM NHC AT HTTPS://HURRICANES.GOV. A MAP OF THE CONDENSED
OFFSHORE FORECASTS CAN BE FOUND HERE FOR OPC:

THE NWS’S NATIONAL DIGITAL FORECAST DATABASE (NDFD)
HTTPS://DIGITAL.WEATHER.GOV/ PROVIDES GRAPHICAL FORECASTS OF
WINDS, WIND GUSTS, WAVE HEIGHTS, AND OTHER WEATHER-BASED HAZARDS
OVER THE OCEANIC DOMAIN. THESE FORECASTS PROVIDE MORE LOCALIZED
INFORMATION THAN THE BROADER CONDENSED VERSIONS OF OFFSHORE
FORECASTS.
