The Collin County Sheriff's Office has confirmed that 15 cars and 2 semis were involved in a traffic pile-up on U.S. Highway 75 southbound in Melissa, Texas, on Friday.

Cars were sliding off the highway due to sudden and heavy snowfall in North Texas causing several separate crashes, according to NBC 5. Initial reports suggested the more than 40 vehicles were involved.

Due to treacherous road conditions, officials in Fort Worth have closed Interstate 30 and Interstate 35W. Fort Worth Police told NBC 5 that as of 11:15 a.m. CT the department was responding to 75 different crashes.

The snowstorm began at 8 a.m. on Friday. No fatalities have been reported, although there were paramedics on the scene.
