INDIANAPOLIS (AP) — The National Weather Service says a tornado has struck suburban Indianapolis

The weather service says the EF-1 tornado struck Greenwood on Wednesday. Details about the twister were not immediately available, but such storms can pack winds of 86 to 110 miles per hour.

Indianapolis television stations showed images of damage including a portion of a roof blown off of a veterinary office.

The tornado occurred as spring-like storms raked Indiana, toppling semitrailers on highways and leaving thousands of people without power.

Power companies reported 16,500 customers without service across Indiana early Wednesday evening.
