State police are warning motorists to slow down if traveling this morning on Interstate 89, north of Exit 10, because of "flash snow squalls" and icy roads that have resulted in cars sliding of the highway and some car crashes.

About 9:30 a.m., troopers were dealing with multiple cars off the road and some crashes.

Earlier in the morning, the left lane of I-89 north in New London, just south of Exit 12, was shut down shut down due to an accident.

About 6:30 a.m., a stretch of the highway just north of Exit 14 in Enfield was closed for another crash. It reopened about two hours later after the crash was cleared, according to the state Department of Transportation.

Highway crews are treating the highways but state police said motorists still should slow down.
