The nationwide network of radio stations broadcasting continuous weather information from the National Weather Service is called NOAA Weather Radio. It provides real-time weather alerts, forecasts, and other emergency information to the public 24 hours a day.
The National Weather Service has offices around the country mostly at airports that gather information such as temperature, humidity etc all funded through your tax dollars. Radar and satellite are also provided by the NWS. Weather information is gathered by the NWS and made public. Even the weather channel, accuweather and all of the other companies that provide weather information get their weather data from the National Weather Service. These other companies tweak that info and may even charge you for it if you sign up with their services. In any event. It all is gathered by the National Weather Service.

Accuweather provides an attractive and adequate 7 day forecast for the Southern California area and the rest of the world on their website. They also offer apps for smartphones and widgets for computers for ease of access to the latest weather information.
A station model located 300km west of California would represent data from a weather station or buoy situated in the Pacific Ocean. This data may include information on temperature, wind speed and direction, atmospheric pressure, and weather conditions at that location.
