1950: A hailstorm struck southern parts of Oklahoma City on this day. The storm damaged about 4,000 homes, 300 businesses, and 750 cars, resulting in a loss estimated at $987,000.
1961: Super Typhoon Nancy was an incredibly powerful tropical cyclone of the 1961 Pacific typhoon season. The system had possibly the strongest winds ever measured in a tropical cyclone and caused extensive damage and at least 173 deaths and thousands of injuries in Japan and elsewhere. A reconnaissance aircraft flying into the typhoon near its peak intensity on September 12 determined Nancy's one-minute sustained winds to be 215 mph. If these values are reliable, they would be the highest wind speeds ever measured in a tropical cyclone. However, it was later discovered that measurements and estimations of wind speeds from the 1940s to 1960s were excessive. Thus, Nancy's winds may be lower than its official best-track value.
Typhoon Nancy made landfall on September 16 over Muroto Zaki.

1988: An afternoon F1 tornado skipped across sections of Indianapolis, Indiana, damaging roofs and automobiles.
1999: Hurricane Floyd, a Category 4 storm with top winds of 145 mph, was making residents along the U.S. East Coast very nervous as it steamed steadily westward. Floyd was once forecast to strike Florida but turned away. Instead, Floyd hit the Bahamas at peak strength, causing substantial damage. It then paralleled the East Coast of the United States, causing massive evacuations and costly preparations from Florida through the Mid-Atlantic States.
Above is a visual comparison of Hurricane Floyd and Hurricane Andrew. The two storms are at similar positions and nearly equal intensities (933 mbar), but Hurricane Floyd is remarkably more massive.
2006: Major flash flooding occurred in a matter of minutes after torrential rain starting pounding the city of Evansville, Indiana. A total of about 250 occupied structures sustained some degree of damage. Over 30 water rescues were conducted from cars stalled in floodwaters.
