December 16th

Local and Regional Events:

December 16, 1967:

With temperatures in the upper 20s, heavy freezing rain fell in west central and southwest Minnesota at night on the 16th, causing widespread ice accumulations on all exposed surfaces, and power and telephone poles and lines went down over a vast region. Some places were without power and phone service for three to four days. This storm was classified as the most severe ice storm in the past 20 years in some areas. Reports were received of turkeys and other poultry dying due to the cold in the countryside. 20 to 30 cars were in the ditch on one slick stretch of road in Rock County. Further west, throughout eastern South Dakota, freezing rain for most of the day formed ice from 3/8 to 3/4 inch on exposed surfaces. Extensive damage was caused to utility lines. All roads became dangerous for traveling, and one death was directly linked to the ice storm. The ice cut off a regular water supply, causing one person to attempt to get water from a cistern. She slipped on the ice into the cistern. Three deaths were indirectly related to the ice storm; two due to automobile accidents, and one due to a heart attack.

 

December 16, 2000:

Northwest winds of 30 to 50 mph, with gusts to 60 mph, combined with newly fallen snow and arctic air to bring widespread blizzard conditions and extreme wind chills as low as 70 below zero to west central Minnesota and much of South Dakota from late on the 15th through the 16th. Events were canceled, travel was shut down, and some motorists were stranded. Both US Highway 12 and Interstate 29 in South Dakota were closed throughout the day. As an indirect result of the low visibility, a semi-truck hit and totaled a pickup truck in the snow just west of Clark.

U.S.A and Global Events for December 16th:

December 16, 1811:

An estimated Magnitude 7.5 earthquake struck the Mississippi Valley near the town of New Madrid in Missouri at 2:15 am local time. People were awakened by the shaking in New York City, Washington D.C., and Charleston, South Carolina. The ground motions were described as most alarming and frightening in places like Nashville, Tennessee, and Louisville, Kentucky. In the epicentral area, the ground surface was described as in great convulsion with sand and water ejected tens of feet into the air.

Central US Seismicity Map

This map shows earthquakes (circles) of the New Madrid and Wabash Valley seismic zones (orange patches). Red circles indicate earthquakes that occurred from 1974 to 2002 with magnitudes larger than 2.5 located using modern instruments (University of Memphis). Green circles denote earthquakes that occurred before 1974 (USGS Professional Paper 1527). Larger earthquakes are represented by larger circles. Map and information courtesy from the USGS.gov.

December 16, 1941:

In 1941, only two women were employed by the Weather Bureau. By 1945, more than 900 women are employed by the Weather Bureau as observers and forecasters, as a result of filling positions of men during World War II. Eleven days after Pearl Harbor, the Army requested that all weather broadcasts be discontinued. The fear was that the enemy would use this information to plan an attack on the United States.
