What happened
late season hail storm moved from Fortuna to Noonan destroying everything in its path. 180 thousand acres of crops were either severely damaged or destroyed.
- Blizzard01/09/1997
Divide
$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...

Divide
$750K damage
What happened
Multiple locations lost power as a result of frost accumulating on power lines due to the multi-day dense fog event, with some locations losing power for more than a day. Multiple lines were downed as conductors broke, or snapped. Approximately 20 poles and multiple cross-arms were broken due to the additional weight of the frost on power lines. 26 additional workers were brought in by the local electrical co-op to assist with the damage.
