INDIANAPOLIS — UPDATE 2:45 a.m. – the previously-issued tornado watch has been extended to include all of central Indiana through 10 a.m. as this line of storms continues to track across the state during the overnight hours. The line has a history of producing damaging winds and rotating storms.

At 1:20am, the line of storms is in eastern Illinois and moving our way. There are still several tornado warnings in this line and western Indiana needs to be prepared to take shelter as the storms move in.

A new severe thunderstorm watch is in effect for northern Indiana until 9am.

A powerful storm system is moving our way with high wind and the threat of tornadoes. A tornado watch is in effect for western Indiana until 4 a.m.

Severe weather events are more dangerous at night when severe weather is difficult to spot and when people are sleeping. We encourage you to have several ways to get warnings overnight. Make sure your cellphone is charged and the volume is up so you can hear it if a warning is issued. Prepare now for what to do in the event of severe weather.

There will be two rounds of storms. One is overnight and the other is later in the day on Saturday. The greatest threat of severe weather with rotating storms is with round one. A few strong to severe storms are also possible later Saturday. Heavy rain may cause flooding and winds will be strong through the Saturday.
