BLIZZARD: A winter storm which produces the following conditions for at least 3 hours: 1) sustained winds of frequent gusts to 35 mile per hour or greater 2) considerable falling and/or blowing snow reducing visibility to less than 1/4 mile. BLIZZARD WARNING: Issued when blizzard conditions are life threatening. In Michigan, the criteria is a sustained wind or frequent wind gusts to 35 mph or more and considerable falling and/or blowing snow reducing visibility frequently to less than 1/4 mile for a duration of 3 hours or longer. 14 1 NOAA Weather Radio Heat Index The fastest and most reliable means of receiving criti- cal weather information is through use of a NOAA The Heat Index is a measure of how hot it really feels Weather Radio with an automatic "tone alert" feature. when the relative humidity (RH) is added to the actual You will receive the warning directly from the National air temperature. This index was devised for shady, light Weather Service in just a couple of minutes from its wind conditions. Exposure to full sunshine can increase issuance. These radios can be purchased in most stores that carry small electronics. Immediately following the issuance of a tornado warning by the NWS, the "tone alert" is instantly sounded, followed by warning infor- mation. This is especially useful when severe weather is expected during the nighttime hours when people are sleeping, and when windows are closed, preventing sirens from being heard. In addition to the tone-alert, the new generation of weather radios receive a digital burst of information. This information is used to tell your radio to warn you only when weather is to affect your specific county. The National Weather Service refers to this digital informa- tion as "Specific Area Message Encoding" (SAME). The radio's "tone alert" feature and SAME are used for the issuance of all weather warnings as well as se- vere thunderstorm, flash flood, hurricane, and tornado watches. NOAA Weather Radio broadcasts 24 hours a Wind Chill Index day, seven days a week with the latest weather informa- tion from daily forecasts to special weather statements about sudden shifts in the weather patterns or the devel- opment of potentially hazardous weather. The Wind Chill Index is based on the rate of heat loss from exposed skin caused by the combined effect of wind and cold.

  • Weather Emergencies
    MAYVILLE STATE UNIVERSITY EMERGENCY AND CRISIS MANAGEMENT PROCEDURES Weather Emergencies Tornados and Thunderstorms All students and personnel are urged to register with the Mayville State University emergency notification system for fast notifications of all emergencies. A tornado watch means that tornadoes could develop in the designated area; A tornado warning means that a tornado has actually been sighted in the area or is indicated by radar. A severe thunderstorm watch indicates the possibility of thunderstorms, frequent lightning and/or damaging winds, hail, and heavy rain. A severe thunderstorm warning means that a severe thunderstorm has actually been sighted in the area or is indicated by radar. If warnings are issued, or if threatening weather approaches, seek shelter immediately. If you are outdoors: Seek inside shelter immediately; Do not try to outrun tornadoes in vehicles, but leave them and seek indoor shelter or low spots off the side of roads; Once you are in a building: Move to a safe area, such as a basement; If underground shelters are not available, move to interior rooms or hallways on the lowest floors and get under sturdy pieces of furniture; and Stay away from windows. Winter Storms A winter storm warning means severe winter weather is imminent or very likely within 12 hours. A winter storm watch means at least four inches of snow in 12 hours, or six inches in 24 hours, or significant ice accumulations are possible within 24-48 hours. A winter weather advisory means cold, ice, and snow are expected to cause significant inconvenience and may be hazardous, but probably not life threatening.

  • Winter Weather Definitions and Terms
    Definitions of Winter Weather Terms used by the National Weather Service As winter approaches, you should understand winter weather terms and be aware of winter weather hazards. The National Weather Service uses several terms to tell you exactly what kind of weather to expect, please review the terms below to familiarize yourself with them. 1) WINTER STORM OUTLOOK This is a statement issued when there is a chance of a major winter storms from 3 to 5 days in the future. This is meant to assist people with their long range plans. However, since the outlook is issued so far in advance, the accuracy of the prediction may be limited. 2) WINTER STORM WATCH This means there may be hazardous winter weather due to various elements such as heavy snow, sleet, or ice accumulation from freezing rain. In our region, heavy snow means 7 inches or more of accumulation in 24 hours or less. A "WATCH" is a long range prediction. They are issued at least 12 hours before the hazardous winter weather is expected to begin. When the storm becomes imminent, or has a high probability of occurring, the watch will be upgraded to a "WARNING". 3) WINTER STORM WARNING FOR HEAVY SNOW Seven inches or more of snow will fall within a 24 hour period. 4) WINTER STORM WARNING FOR SEVERE ICING Heavy accumulation of ice due to freezing rain will down trees and power lines. Electricity, or telephone communications, may be out for a long period of time. Roads may become impassable for most vehicles. 5) BLIZZARD WARNING This is issued for a combination of strong winds averaging or frequently gusting to, or above, 35 miles an hour and very low visibility due to blowing or falling snow.

  • Winter Weather Awareness Winter Storm Warning
    BE PREPARED… BEFORE THE STORM STRIKES! WINTER WEATHER AWARENESS WINTER STORM WARNING Normally, when a winter storm is expected, the National Weather Service will issue a winter storm watch. A winter storm watch means that conditions exist for the occurrence of severe winter weather such as blizzard conditions, heavy snow, significant freezing rain, or sleet. A winter storm watch is your signal to prepare for the storm now. Once the storm begins, travel may not be possible. Preparing at Home and at Work Remaining inside protected from the elements is the safest place during a winter storm. Consider a plan for the potential loss of heat, power, telephone service, and a shortage of supplies if the storm persists. Here is a checklist you can use to be prepared. Preparing for the Indoors • Flashlight with extra batteries; • Battery powered weather radio and portable radio; • Extra food and water, especially high energy food that requires no cooking or refrigeration such as dried fruit and canned goods (don’t forget the non- electric can opener); • Medicine, first aid supplies, and ample baby supplies; • Emergency heating source, such as a stocked fireplace, wood stove, or space heater; • Smoke detector and fire extinguisher, the chance of fire increases dramatically using alternative heating! • Carbon monoxide detector. Don’t forget, you may not be at home when the storm strikes! Have emergency supplies available at your place of work. Preparing Your Vehicle About 70% of deaths during an ice or snow storm occur in a vehicle. If you question if you should attempt to travel, then don’t! If you must travel then allow extra time.

    ■ Ensuring a safe and secure homeland for all North Dakotans ■ Winter Season - Watch The National Weather Service issues Watches when the risk of a hazardous winter weather event has increased, but the occurrence, location, and/or timing is still uncertain. Watches are issued to highlight significant and life threatening situations that may occur or are possible in the next several days. The significant winter weather could be heavy snow, freezing rain, sleet, blowing snow, extreme cold, blizzard, or combinations of these. Watches are issued for Winter Storms, Blizzards, and Extreme Cold, depending on what the threat is. Watches may be dropped (cancelled), or upgraded to advisories or warnings. ■ Winter Season - Warning The National Weather Service issues Warnings when life threatening winter weather is imminent, or occurring. Anytime you hear the National Weather Service has issued a Warning (winter or summer), you should be thinking of life threatening dangerous weather. There are four types of warnings issued for winter weather: Winter Storm Warning; Blizzard Warning; Ice Storm Warning; and Extreme Cold Warning. ■ Winter Storm Warning - 6 inches (or more) of snow is expected in a 12 hour (or less) period of time, OR, when 8 inches (or more) of snow is expected in a 24 hour (or less) period of time. Winter Storm Warnings may also be issued for combinations of snow, wind, blowing snow and dangerously cold conditions. ■ Blizzard Warning – (the most deadly winter events in North Dakota) –considerable falling and/or blowing snow combined with winds of 35 mph or more and reducing visibility to less than ¼ mile (near zero), and lasting at least 3 hours.
