A National Weather Service "Marine Point Forecast" refers to a text forecast for a single point generated from a forecaster-generated gridded data set known as the National Digital Forecast Database (NDFD) also used to produce graphics. The NDFD is used as the basis for the majority of local public and marine forecasts and is in the process of being further expanded to the offshore and high seas areas.
In actuality, the "point" is a single small rectangle which represents the resolution of the computer forecast models which is typically 2.5 by 2.5 kilometers.
Please Note: Being a forecast for a single point, the point forecast is very specific and mariners should also be aware of weather conditions in the surrounding area. Forecast information for the surrounding area can be found within the zone forecast and the NDFD graphics. Be aware, the forecast conditions at a particular point may not exceed the criteria of a Small Craft Advisory, Gale, Storm etc. These watches/warnings/advisories are issued for the entire zone in which the point resides and mariners should act accordingly.
