Having a police scanner can be very helpful during a severe weather event. With most scanners you can get updates on weather via NOAA Weather Radio. Most police scanners can also alert you when there is severe weather coming, such as hurricanes, tornados, severe thunderstorms and so on. Monitoring your local, county and state public safety agencies with your scanner will keep you informed what going on during the event and with the weather radio features you can also check for weather alerts as well.
