For areas shaded pink, a winter storm warning has been issued, while a blizzard warning has been issued for areas shaded red.

Gov. Phil Murphy has declared a state of emergency ahead of the weekend storm that could bring snowfall of four to 11 inches to the Princeton region.

The National Weather Service in Mount Holly has issued a winter storm warning for the region that will begin at 7 p.m. Friday and end at 7 p.m on Saturday. For some areas of the state, the National Weather Service has declared a blizzard warning.

Winds gusting as high as 35 miles per hour are possible in portions of central, northern, northwest, and southern New Jersey and southeast Pennsylvania. Travel could be very difficult to impossible, and blowing snow could significantly reduce visibility. Accumulating snow is expected to begin Friday evening, becoming heavy at times Friday night through Saturday morning. Snowfall rates near one inch per hour are possible, with significant reductions in visibility. Snow will diminish late Saturday afternoon. If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency.

Expect delays if you must take public transportation. NJ Transit and private bus carriers will be cross-honoring tickets and passes.

The state of emergency declared by the governor will take effect at 5 p.m. across all 21 New Jersey counties.

“The anticipated winter storm is forecasted to bring heavy snowfall and high wind gusts statewide, with blizzard conditions in some areas of New Jersey,” Murphy said. “Road crews will be deployed throughout the state for salting and snow plowing purposes. Residents should take extreme caution, stay off the roads, remain vigilant, and follow all safety protocols. ”

Commercial vehicle restrictions will be in place as of 5 p.m. on Friday on multiple interstate highways.

“Troopers are ready to assist residents and commuters throughout the state, both on and off of the highways, for the duration of the storm should they be needed,” said New Jersey State Police Superintendent and State Director of Emergency Management Colonel Patrick Callahan. “We cannot do it without you, and we ask you stay off the roads if possible so plow crews can do their jobs. Please use caution when traveling and prepare an emergency kit for use at home and for your vehicle.”
