This is an open net and everyone with in an interest in weather or weather-related phenomenon are welcome to participate. Affiliated with the National Weather Service (NWS) NorCal SkyWarn is a critical first line of defense for severe weather threats such as storms, damaging winds, flash floods and tornadoes. Volunteers known as “spotters” receive training on identifying hazardous weather events and work with the NWS to report weather observations in real time. The NorCal SkyWarn net is linked through Echolink to other repeaters in our region including W6CX (Mt. Diablo) and K6MVR (Mt. Vaca). Online advance check-in to the net can be made by sending an e-mail to checkin@norcalskywarn.org with your name, call sign (if applicable), spotter number (if applicable) and location.
