Sleet in Somerville causes traffic, accidents

Steady rain and sleet made commuting a mess in Somerville Sunday.
Wintry conditions caused slowdowns and a variety of reported accidents on New Jersey roadways.
Part of I-80 was shut down when a tractor-trailer rolled over in Warren County.
Gov. Phil Murphy urged New Jersey drivers to avoid driving on the roads during the storm if possible. Sleet, rain and snow are expected to continue through the day Monday.
