  • Blizzard01/09/1997

    Foster

    1 death, $1.5M damage

    What happened

    The second blizzard in less than 1 week brought North Dakota to a virtual standstill. This blizzard didn't bring as much snow as the first storm, but the winds gusted from the northwest as high at 40 mph and they lasted for 3 days. Snowfall amounts from this storm varied from 1-2 inches in the southwest to 2-4 inches in the central. But the strong winds combined with this snow as well as the snow from the blizzard a few days earlier created widespread whiteout conditions that lasted for 3 days. There were numerous communities that halted mail delivery and cancelled school. In Emmons Co. every road was blocked by drifts, some as high as 18 feet. In McLean Co. there was a drift at the intersection of highways 83 and 37 that was 12 feet high and 150 yards long. It took snow plow operators working from both directions 10 hours to open. The Standing Rock Indian Reservation had severe hardship with snow drifts taller than buses blocking all the entrance roads. Most of the people on the reservation ran out of propane to heat their homes, and food shortages were widespread. Again, almost every major road in North Dakota was closed and plows pulled off. In Foster Co., the county road...

Vehicle damage was also surveyed, including to a semi tractor that was struck by a grain bin. Agricultural damage was severe and extensive.

  • Blizzard01/15/1997

    Foster

    1 injured, $900K damage

    What happened

    The 3rd blizzard to hit North Dakota in less than 3 weeks affected mainly the east-central and eastern part of the state. Again, like the previous blizzard, the winds was the major weather factor. Wind gusts at times were over 50 mph. This created widespread blowing and drifting snow. All major roads in the area were closed again for the 3rd time this year. In Logan Co. the machine shed that is used by the Logan Co. Historical Society to store antiques was damaged by the roof falling in. With the severity of the blowing and drifting snow, roads that were just opened from the last storm were once again blown shut. This lead to the death of a 71 yr. old Fredonia(Logan Co.) man. He suffered a heart attack at his farm, and was able to call 911 for help. However, the ambulance couldn't get to him because of the blocked roads. A 57 yr old man from Napoleon(Logan Co.) also suffered a heart attack on his farm and passed away before assistance could get to him. Injuries and dollar damage amounts estimated.

  • Blizzard04/05/1997

    Foster

    $1M damage

    What happened

    Warm weather the first three days of April lead much of North Dakota to believe that spring had arrived with temperatures in the 60s and 70s. Mother Nature had other plans. A very strong area of low pressure moved out of the Colorado area into the northern plains. Warm moist air ahead of the low collided with cold air coming down from Canada. The result was the worst blizzard of the season for North Dakota, bringing much of the state to a complete halt. The precipitation began to fall during the afternoon of the 4th (Friday), as rain in the east and freezing rain or sleet in the west. By Friday evening the freezing rain and sleet had changed over to all snow in the west. By Saturday afternoon the heavy snow moved into the central part of the state, reaching trhe eastern part of North Dakota later that night. Snow accumulations were on average 1.5 to 2 inches an hour with 50 to 60 mph winds as well. The blizzard ended in the west on the morning of the 6th (Sunday), but continued into the evening across the east. The additional snow at Bismarck brought the season snowfall total to 101.4 inches, which set an all time record. The old record was 91.8 inches. In Jamestown, they...
