BOONVILLE, Ind. -- Hundreds of homes and businesses in southwestern Indiana were still without power Sunday following a powerful storm that caused more than $100 million in damage according to a National Weather Service estimate.
Vectren Energy Delivery estimated more than 1,900 of its electric customers had no power midday Sunday, nearly two days after the storm -- deemed a microburst -- brought wind speeds of up to 120 mph.
Friday's storm damaged 100 structures, with dozens destroyed, and snapped or blew over hundreds of power poles, the weather service said. Damage to one farm was estimated at more than $2 million.
The city of Boonville, about 15 miles northeast of Evansville was still under a state of emergency Sunday.
Straight-line winds Friday afternoon ripped off a portion of the high school's roof. Though much of the damage was repaired Saturday, but it remained uncertain whether classes would be held Monday.
"Our campus is going to look a lot different," Boonville High School Principal Mike Whitten told the Evansville Courier & Press.
About 125 students were in the school's auditorium when the storm approached and staff ushered them into safer areas like bathrooms.
No injuries from the storm were reported.
More severe thunderstorms moved through southern Indiana on Sunday, but had not caused significant damage through the early afternoon.
Friday's storm lasted 32 minutes and struck an area 35 miles long and up to four miles wide, the National Weather Service said of the microburst, which occurs when cooler air rushes downward out of a thunderstorm, hits the ground and rushes outward.
Wind speeds averaged 60 mph to 90 mph, with frequent peaks over 100 mph and one peak wind estimated at 120 mph, the weather service said.
Before the storm hit Boonville, it swept through Evansville, where three homes were destroyed and about 20 other homes and businesses damaged, Vanderburgh County Emergency Management Director Cliff Weaver said.
"Based on the level of damage ... it will take a couple of days if not a couple of weeks to clear all the debris," Mayor Lloyd Winnecke told WTVW-TV. "We've seen amazing devastation in some places."
The winds ripped a garage and roof from a vacant home as neighbors watched.
"We were standing at our front door and the next thing we knew, the man's garage was in our front yard," Cheryl Koch told the Courier & Press.
