Montclair is seeing its first snow accumulations of the season Friday, the same week icy conditions caused dozens of crashes — some of them involving dozens of vehicles — on New Jersey roads.

The National Weather Service has issued hazardous weather and winter weather advisories from midnight Friday through noon. Total snow accumulations in the region are estimated at 3 to 5 inches, according to the NWS.

It warned to expect slippery road conditions and impacts on the morning commute. Snowfall rates could be between half an inch and a full inch per hour, and there could be heavy snowbands.

Residents can receive township alerts through the Swift911 service.

Parking on snow-covered streets is prohibited by township ordinance 327-25. The no-parking prohibition remains in effect for a period of 12 hours after snowfall has stopped in order to facilitate snow removal. The township Thursday declared a state of emergency for the storm, and said cars on snow-covered streets would be ticketed.

Residents may park their vehicles free of charge in municipal lots and decks from 6 p.m. Thursday until streets have been cleared of snow.

Montclair Public Schools are closed Friday because of the forecast, but the district will continue to hold afternoon coronavirus testing  at Montclair High School’s George Inness Annex Atrium, from 4 to 6 p.m. Additional testing dates are set for Jan. 14 and 21, and testing is provided by Medi Mobile of Livingston.

Trash collection in Section 2 and recycling of mixed paper in Montclair's business districts will not be collected on Friday, but will instead be collected Saturday. The township asks that materials not be put out until after 6 p.m. on Friday.
