More than a foot of snow dropped in some parts of Indiana, and freezing rain led to power outages in other areas during a powerful winter storm that stretched from Tuesday into early Wednesday.

The storm prompted hundreds of school and business closings and delays. Road conditions were extremely hazardous across the 6News viewing area, and many flights were canceled at Indianapolis International Airport.

Police said snowy highways caused two fatal crashes -- the only known deaths from the storm. In one wreck, a 20-year-old LaPorte woman lost control of her car on a snow-covered U.S. 20 near Michigan City in northwest Indiana and died of her injuries.

In the other wreck, a Michigan woman died from injuries she suffered when the tractor-trailer she was driving overturned on Interstate 69 about 30 miles north of Fort Wayne.

To the north of Indianapolis, snow was the primary form of precipitation. As many as 18 inches of snow fell in the northern part of Indiana. By 11 p.m. Tuesday, at least 13 inches had fallen in Attica, Elwood, Hartford City, Rossville and Winchester. By Wednesday morning, 16 inches and 17 inches were reported on the ground in Frankfort and Lafayette, respectively.

Strong winds were causing blowing and drifting snow, especially north of Indianapolis, and several counties issued travel restrictions, some limiting travel to emergency vehicles only.

In the Indianapolis area, as many as 9 inches of snow fell. The area received snow Tuesday morning and Tuesday evening, with sleet and freezing rain falling in between.

Snow accumulations were lower south of Indianapolis -- the Franklin area, for example, had 6 inches of snow by 11 p.m. -- but those areas had more freezing rain, coating trees and power lines and causing power outages for thousands of Duke Energy customers.

A blowing snow advisory was posted for Wednesday for much of central Indiana, but that advisory was dropped before noon.

As the storm moves away, Indiana will once again plunge into a deep freeze, with temperatures expected to be in the teens for daytime highs in the northern half of the state. Low temperatures will again be near zero.
