Weather History - July 30th

Local and Regional Events:

July 30, 1981:

Operation Skywarn organized by the National Weather Service in Bismarck four years ago had a perfect opportunity to put the training into operation on this day. A spotter 20 miles west of Bismarck identified a rotating wall cloud 10 minutes before a tornado touchdown. The strong tornado was rated as having F3 strength, leaving behind an 18-mile long path of destruction. The force of the storm drove a stick between a tire and rim. A 6-inch steel beam was twisted and found near the high tension tower which had been toppled.

July 30, 2001:

Strong winds of 81 mph blew much of the roof off of the bowling alley in Mobridge. Some flying debris also damaged a trailer home. Many trees were snapped in two or uprooted, and many power lines were downed. High winds brought down tree branches and also knocked the power out for several hours in Pollock.

July 30, 2010:

Very heavy rains of 5 to 10 inches caused the Rosehill Dam to break in the early morning hours in southeast Hand County. Flash flooding began around 1 am CDT with two campers being swept up around 130 am CDT. The two campers clung to a tree until they could be rescued about 6 am CDT. They were both injured with one camper being treated for hypothermia and other airlifted to Sioux Falls for broken ribs and head trauma. The dam broke at 330 am CDT with the spillway breaking at 420 am CDT. There was between a 100 to the 150-foot hole left by the dam break. The flash flooding continued downstream on Sand Creek causing damage to area farms, filling basements, and flooding many roads.

U.S.A and Global Events for July 30th:

1970: Hurricane Celia was born in the northwest of the Caribbean Sea on this day. The hurricane would be one of the worst ever to hit Texas and would reach Texas late on August 3. The storm reached its peak as it made landfall near Corpus Christi, Texas, as a strong Category 3 hurricane. Hurricane Celia is currently the last major hurricane to make landfall on the middle Texas Coast until Hurricane Harvey in 2017.
