NATIONAL WEATHER SERVICE PRODUCTS VIA WWV, WWVH HF VOICE

The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards, broadcasts a time and frequency service from stations WWV in Fort Collins, CO and WWVH in Kauai, Hawaii., commonly known to mariners as the "Time Tick", used as an aid in celestial navigation. Included in these are hourly voice broadcasts of current highseas storm warnings for the Atlantic, Pacific and Gulf of Mexico provided by the National Weather Service.

Discrimination between the two stations may be accomplished as WWV uses a male announcer for announcement of time, while WWVH uses a female announcer.

For some further information on WWV, WWVH and time signals worldwide, see NGA Publication 117 "Radio Navigational Aids"

All NWS marine forecasts rely heavily on the Voluntary Observing Ship (VOS) program for obtaining meteorological observations.
