It appears just like a normal winter day in Sault Ste. Marie Saturday afternoon, but things are going to change in a hurry come Saturday night.
Sault Ste. Marie has now been added to a blizzard warning associated with a powerful low pressure system that is carrying with it a mixed assortment of weather types. The low is expected to deepen as it crosses Michigan late Saturday night and advances north east.
Currently the blizzard is falling in the time line of early Sunday afternoon and lasting through Sunday evening.
Blizzard warning in effect for:
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Blizzard conditions with gusty winds and visibility frequently near zero in snow and blowing snow are expected or occurring.
Blizzard conditions and very strong winds are expected to develop Sunday afternoon.
A strong low pressure system will track through the area on Sunday. In the wake of this low, snow and strong northwest winds of 70 km/h gusting to 100 km/h will develop Sunday afternoon. As a result, blizzard conditions with near zero visibilities are expected beginning Sunday afternoon and will persist into Monday morning.
The strong winds may also result in damage to buildings, such as to roof shingles and windows. High winds may toss loose objects or cause tree branches to break. Power outages are also possible.
Additional snowfall amounts Sunday afternoon and Sunday night will be near 10 to 15 cm.
The strong winds will slowly ease through the day on Monday, and visibility will also improve.
Note that a freezing rain warning is also in effect for tonight into Sunday morning.
Travel is expected to be extremely hazardous due to reduced visibility. Road closures are possible. Consider postponing non-essential travel until conditions improve.
Blizzard warnings are issued when widespread reduced visibilities of 400 metres or less are expected for at least 4 hours.
