Door and Kewaunee counties are under multiple winter weather alerts as a powerful storm system moves toward northeast Wisconsin.

The National Weather Service in Green Bay has issued a winter weather advisory from 10 p.m. Thursday until 1 p.m. Friday for Door and southern Oconto counties. Forecasters say 2 to 4 inches of snow is expected overnight, with wind gusts up to 45 mph creating blowing and drifting snow and reduced visibility during the Friday morning commute.

A winter storm watch is also in effect from Saturday evening through Monday afternoon for Door and southern Oconto counties. Heavy snowfall is possible, with 12 to 18 inches of accumulation forecast and isolated areas potentially seeing more than 24 inches.

Strong winds could combine with the heavy snow to bring down tree branches and power lines, raising the risk of scattered power outages. Whiteout or near-blizzard conditions could also develop, making travel difficult or potentially dangerous across Door and neighboring Kewaunee counties.
