so any weather net, like we have in the midwest would have been useless. Weather radar on phones is great but it lacks eyes on the ground, which hams can provide. Many times here the weather bureau has wind indications by radar but further responses from radio operators on the ground, have resulted in weather emergencies being sat on .
Skywarn is usually active for larger storms, but I usually just pay more attention to CalTrans and County Roads. That, and the standard FD and Lifeguard channels, for possible rescues, which can and do pop up in some unexpected areas.
