WEST LAFAYETTE, Ind. (AP) _ Purdue University has called off all Wednesday classes at its West Lafayette campus because of the winter storm.

Purdue had planned to resume classes Wednesday afternoon, but now say normal operations won't resume until Thursday. Purdue officials say they're concerned about road conditions for those commuting to campus.

The Indiana-Purdue campus in Fort Wayne is closed Wednesday, while IUPUI in Indianapolis is remaining closed through 5 p.m. Wednesday.

Indiana University is keeping the Bloomington campus on its normal schedule, but the storm has led to closings or delays at IU regional campuses in Kokomo, Richmond and New Albany and Ball State University in Muncie.
