The National Weather Service is investigating why a warning wasn’t issued in Marysville, Kansas, when a tornado hit the city early Friday morning.

The tornado developed on the southwest side of the town and went through the town about 3:45 a.m., National Weather Service meteorologist Bryan Baerg said. The EF-1 tornado was about 50 yards wide and produced winds of 105 mph.

It dissipated about five miles northeast of Marysville, a town of about 3,300 sitting 60 miles north of Manhattan. Baerg said sirens didn’t go off because a warning wasn’t in effect. He said they are reviewing radar and other data to see what happened and ensure that it doesn’t happen again.
