Wind chill warning goes into effect Friday in St. Lawrence County; wind chill values 25-45 below zero expected

Posted

A wind chill warning is in effect for St. Lawrence County from 4 a.m. Friday until 7 p.m. on Saturday, according to the National Weather Service.

Forecasters expect dangerously cold wind chills with wind chill values ranging from 25 to 45 below zero.

The extreme cold could cause frostbite in as little as 10 minutes to exposed skin, NWS says.

A wind chill warning means the combination of very cold air and the wind will create dangerously low wind chill values. Frostbite can occur quickly and even hypothermia or death if precautions are not taken.

Before the cold, temps will be near 18 today with a chance of snow before 10 a.m., the service says. Less than one inch of snow is possible today.

An overnight low of around -7 is expected with wind chill values of -17. One to two inches of snow is expected overnight, NWS says.

Forecasters say the high on Friday will be -4 with wind chill values around -32. An inch of snow is possible as well.
