A storm watch means severe weather hasn't occurred yet, but upcoming weather conditions are expected to produce potentially dangerous weather, such as heavy rain, hail, or strong gusts of wind. Because conditions can change quickly, the NWS wants to give you as much time as possible to safeguard your personal property and take shelter.
What does "storm warning" mean?
A storm warning indicates that meteorologists have already observed severe conditions. If you hear that a storm warning has been issued, it means potentially dangerous weather is imminent in or near your location. Depending on the type of weather warning, take appropriate action as quickly and safely as possible.
The Outdoor Warning System may be activated for ANY manmade or Natural Disaster. When activated citizens should tune in to local media for further information.
