Probably by the EWS which uses the old civil defense siren system (you should still hear these periodically tested). Check on your local EWS radio or TV station for instructions. It will either tell you that this is a periodic test, or briefly describe the emergency and give instructions on what you should do.
Here in Montana EWS is used allot in the winter to report severe weather conditions and inform people to avoid travel in affected areas, and in the summer to report dangerous Forrest fire conditions (both often without the initial siren).
