A tornado warning is an alert by the National Weather Service confirming a tornado sighting and location. Winds will be 75 mph or greater. The Weather Service will announce the approximate time of detection and direction of movement.
Public warning will come over the radio, TV, or there will be five (5) minute steady blasts of sirens by the Ramsey County Civil Defense Warning System.
An "all clear" will be given over the public address system when the National Weather Service authorizes it.
