Indiana's major electric utilities are reporting more than 40,000 power outages around the state while temperatures plunge well below zero.
The largest number of outages was in Indianapolis, where nearly 27,000 homes and businesses were reported without electricity Monday morning by Indianapolis Power & Light.
A couple thousand outages each were reported in the Terre Haute area and central Indiana's Tipton County.
Sunday's heavy snowfall and strong winds gusting to 35 mph at times have caused many tree limbs to come down on power lines.
Utility officials say crews are working as quickly as possible to make repairs.
Numerous shelters have been opened around the state to assist those without power or stranded travelers.
Indianapolis city spokesman Marc Lotter says emergency crews have helped about 350 people to the several shelters that have been opened around the city.
