Severe Winter Weather Awareness Week is October 27 through 31, 2014 in North Dakota Now is a good time to re-familiarize yourself with winter terms and safety rules. Prepare now for the coming winter! ****Winter Weather Terminology**** A Watch is issued when the risk of a hazardous winter weather event has increased, but its occurrence, location, and/or timing is still uncertain. Watches are issued a day or two, sometimes more, in advance of a possible event. A Warning or Advisory is issued when a hazardous winter weather event is occurring, is imminent, or has a high probability of occurrence. A warning is used when there is a threat to life or property. An advisory is for less serious conditions that cause inconvenience, and, if caution is not used, could lead to situations that may threaten life or property. The goal is to post warnings or advisories a day or so in advance of the expected event. People often ask…why are you telling me now about a storm tomorrow? The answer is simple, so that you have time to prepare yourself and your family for the impacts! Snow criteria for a warning is 6 inches or more in 12 hours or less, OR, 8 inches or more in 24 hours or less. Snow criteria for an advisory is 3 to 5 inches. Note that criteria for warnings and advisories may be lowered (4 to 6 inches) early and late in the snow season, for example in October and May. Winter Storm Warnings and Winter Weather Advisories may be issued for a combination of elements like snow coupled with wind and blowing snow, or snow coupled with sleet and freezing rain. Sleet is pellets of ice. Sleet bounces when it hits the ground. Freezing Rain is rain that freezes when it hits the ground or objects on the ground. It forms a sheet or glaze of ice. Wind Chill is that part of the cooling of a human body caused by moving air. Moving air accelerates the rate of heat transfer away from a human body. Wind Chill Advisory is issued for wind chills of 25 to 39 below zero. Wind Chill Warning is issued for wind chills of 40 below zero and colder.
