Watches and Warnings Winter

Winter Storm Watches, Warnings, and Advisories are issued by individual National Weather Service Forecast Centers. The actual criteria depends on geography and topography.

Winter Storm Watch

a significant winter weather (ie. heavy snow, heavy sleet, significant freezing rain, or a combination of events) is expected, but not imminent, for the watch area; provides 12 to 36 hours notice of the possibility of severe winter weather.

Winter Storm Warning

a significant winter storm or hazardous winter weather is occurring, imminent, or likely, and is a threat to life and property.

Blizzard Warning

winds that are at least 35 mph or greater, blowing snow that will frequently reduce visibility to 1/4 mile or less for a duration of at least 3 hours, and dangerous wind chills are expected in the warning area.

Winter Weather Advisory

when a significant winter storm or hazardous winter weather is occurring, imminent, and is an inconvenience.

Wind Chill Index

is the calculation of temperature that takes into consideration the effects of wind and temperature on the human body. This is not the actual air temperature. Estimate the current wind chill.
