* WHAT...Dangerously cold wind chills of 20 to 40 below zero expected. * WHERE...Portions of northern New York and central, northeast, northwest, and southern Vermont. * WHEN...From 7 PM this evening to 1 PM EST Saturday. * IMPACTS...Frostbite and hypothermia will occur if unprotected skin is exposed to these temperatures. An extended period of freezing temperatures could cause ruptured water pipes. This period of cold temperatures is particularly dangerous and well outside of typically experienced temperature conditions. Risk of hypothermia and frostbite is unusually high, especially for vulnerable populations like the elderly, children, those that do not have ready access to adequate heat, or are outdoors and not taking actions to mitigate these conditions.

Total snow accumulations between 9 and 16 inches with locally higher amounts possible. * WHERE...Portions of northern New York and central and southern Vermont. * WHEN...From 1 PM Sunday to 1 AM EST Tuesday. The heaviest snowfall rates will occur Sunday night into Monday morning. * IMPACTS...Roads, and especially bridges and overpasses, will likely become slick and hazardous. Travel could be very difficult to impossible. The hazardous conditions could impact the Monday morning and evening commutes.
