At least 50 to 100 cars were involved in a massive pileup Friday morning amid snow squalls on Interstate 93 in North Ashland, N.H., state police said.

The accidents occurred after an unexpected snow squall struck the area around 9:40 a.m., limiting visibility in the northbound lanes of the highway to almost zero and sending some 50 to 100 vehicles sliding into each other, The Boston Globe reported.

On Friday morning, traffic was heavy since many drivers were likely heading for a ski weekend, authorities said, adding that since snow has been falling on and off in the state, a majority of the highway was snow-covered.

Around 9:45 a.m., police started receiving calls about the crash, WCVB-TV reported.

The conditions were described as blizzard-like after a quick-moving snow squall dumped a band of white stuff on the area some 90 miles west of Portland, Maine, with one photo on Twitter showing a tractor-trailer on fire after having burst into flames.

Although the number and the severity of injuries remain unknown, some injuries have been reported in the crash, New Hampshire State Police Lt. Jerome Maslan told CBS News. However none of them are considered to be life-threatening, State Police dispatcher D. Joseph Miller in the Twin Mountain Barracks added.

Currently, the northbound side of I-93 north has been closed down past exit 24 to clear the massive wreck and authorities are directing traffic off exit 22 in order to make room for emergency vehicles, said State Transportation spokesman Bill Boynton.

It's unclear when the road is expected to reopen and authorities have yet to announce any confirmed injuries stemming from the wreck.

Meanwhile, a second crash was reported on Interstate 89 in Sutton, N.H.
