September 15th

Local and Regional Events:

September 15, 1977:

Sioux Falls residents received a rude awakening during the morning hours as thunderstorms rolled through the city. Over two and one-half inches of rain fell in the city in an hour and 15 minutes. A large amount of rain in a short period led to street flooding in some areas. Lightning strikes from the storms also started several small fires.

U.S.A and Global Events for September 15th:

1747: Some historical accounts of a hurricane caused flooding on the Rappahannock River in Virginia. A slave ship was overturned, and several fatalities were reported.


1945: A hurricane entered the south Florida coast at Homestead, curving northward right up through the center of Florida, remaining over land, and exited near Jacksonville Beach with winds gusting to 170 mph. The following is from the Homestead Air Reserve Base. “On Sept. 15, 1945, three years to the day after the founding of the Homestead Army Air Field, a massive hurricane roared ashore, sending winds of up to 145 miles per hour tearing through the Air Field's buildings. Enlisted housing facilities, the nurses' dormitory, and the Base Exchange were all destroyed. The roof was ripped from what would later become building 741, the Big Hangar. The base laundry and fire station were both declared total losses. The few remaining aircraft were tossed about like leaves.” Click HERE for more information from Abandoned and Little-Known Airfields.
