Local and Regional Events:

October 17, 1910:

The temperature in Aberdeen, South Dakota, warmed to 90 degrees on this day. This reading is the latest day in the calendar year in which the high temperature reached 90 degrees.

 

October 17, 2011:

A strong low-pressure system to the northwest and a strong high-pressure system to the southeast brought stiff southerly winds across central and north-central South Dakota from the late morning until the early evening. South winds of 30 to 40 mph with gusts over 60 mph caused spotty damage across the region. The high winds created large waves on Lake Oahe near Pierre, which damaged several docks along with some boats at a marina. There were also some tree branches downed across the region, along with some damage to a few structures. With the high winds, warm temperatures, and low humidity, several grassland fires also broke out across parts of the region. The maximum wind gust of 68 mph occurred in Corson County.

 

U.S.A and Global Events for October 17th:

1984: A snowstorm struck northern Utah producing a record 18 inches in 24 hours at Salt Lake City and 40 inches at the nearby Alta Ski Resort. The town of Magna, located ten miles west of Salt Lake City, did not receive any snow at all. The storm was responsible for a fifty-vehicle pile-up along Interstate 15 near Farmington, Utah.

 

1997: Late on October 17, Super Typhoon Ivan attained its peak intensity with winds of 185 mph and an official barometric pressure of 905 mbar. On the same day, while near peak intensity, Typhoon Joan was located about 1300 miles east of Typhoon Ivan.

1998: During the weekend of October 17-18, 1998, torrential rains fell over southern and southeast Texas. Up to 22 inches of rain fell, which first resulted in deadly flash flooding from San Antonio to Austin followed by record-breaking river floods along several South Texas rivers the following week. Based on provisional data from the USGS, which is subject to revision, the flood peak for this event was the highest known peak stage at 15 locations. Tragically, a total of 31 people died during the event (26 drownings, two tornado deaths, two heart attacks, and one electrocution/drowning).  At least 17 of the drowning victims were in vehicles that were either driven into water or were swept away by rapidly rising water.  Preliminary property damage estimates approached three-quarters of a billion dollars.
