The National Weather Service issued a tornado warning well ahead of time, with 35 minutes of lead time before it first touched down, and 50 minutes of lead time before it moved through Siren. The National Weather Service works closely with the local law enforcement, SKYWARN and Ham Radio Networks to reduce the loss of life and property during severe weather. It was this cooperation that helped us to reduce the loss of life with this tornado.
