Welcome to the home of SW CA Skywarn REACT. Chances are if you have found your way here, you know what Skywarn and/or REACT are all about. If not, read on to discover what these organizations are all about.


SKYWARN is a program of the United States’ National Weather Service (NWS). Its mission is to collect reports of localized severe weather. These reports are used to aid forecasters in issuing and verifying severe weather watches and warnings and to improve the forecasting and warning processes and the tools used to collect meteorological data. It consists of a network of severe storm spotters who observe weather conditions and make reports of severe weather to their local NWS offices. These spotters are regularly trained by personnel from the local NWS offices.

1101px-REACT_Color_LogoREACT began as a CB radio Emergency Channel 9 monitoring organization across the United States and Canada in 1962. Initially, the primary role of REACT volunteers was to monitor Channel 9, the CB Emergency Channel, to help motorists. Later, duties grew to include communications after disasters (tornadoes, floods…), and in some places before disasters (storm spotting). As well, REACT safety communications for parades, runs/walks and other community events became prominent. Now, REACT Teams rarely use CB primarily, a large percentage have now added amateur, FRS, GMRS, Multi-Use Radio Service (MURS), Trunked radio systems and business band radio (LMR) to their public service capabilities. Their original purpose, to monitor CB has largely gone by the wayside.
