SEPTEMBER 30TH, 1959-Three tornadoes spawned by the remnants of Hurricane Gracie killed 12 persons at Ivy VA.
SEPTEMBER 30TH, 1959 |
Three tornadoes spawned by the remnants of Hurricane Gracie killed 12 persons at Ivy VA. |
SEPTEMBER 30TH, 1970 |
A nineteen month drought in southern California came to a climax. The drought, which made brush and buildings tinder dry, set up the worst fire conditions in California history as hot Santa Anna winds sent the temperature soaring to 105 degrees at Los Angeles, and to 97 degrees at San Diego. During that last week of September whole communities of interior San Diego County were consumed by fire. Half a million acres were burned, and the fires caused fifty million dollars damage. |
SEPTEMBER 29TH, 1983 |
Heavy rains began in central and eastern Arizona which culminated in the worst flood in the history of the state. Eight to ten inch rains across the area caused severe flooding in southeastern Arizona which resulted in thirteen deaths and 178 million dollars damage. President Reagan declared eight counties of Arizona to be disaster areas. |
SEPTEMBER 29TH, 1927 |
An outbreak of tornadoes from Oklahoma to Indiana caused 81 deaths and 25 million dollars damage. A tornado (possibly two tornadoes) cut an eight-mile long path across Saint Louis MO, to Granite City IL, killing 79 persons. The damage path at times was a mile and a quarter in width. The storm followed a similar path to tornadoes which struck in 1871, 1896, and 1959. |
SEPTEMBER 28TH, 1836 |
The first of three early season snows brought four inches of snow to Hamilton NY, and two inches to Ashby MA. |
SEPTEMBER 28TH, 1893 |
Albuquerque NM was soaked with 2.25 inches of rain, enough to establish a 24 hour record for that city. |
SEPTEMBER 27TH, 1816 |
A black frost over most of New England kills unripened corn in the north resulting in a year of famine. |
SEPTEMBER 27TH, 1959 |
A tornado 440 yards in width traveled twenty miles from near Hollow OK to western Cherokee County KS. Although a strong tornado, it was very slow moving, and gave a tremendous warning roar, and as a result no one was killed. |
SEPTEMBER 26TH, 1936 |
Denver CO was buried under 21.3 inches of snow, 19.4 inches of which fell in 24 hours. The heavy wet snow snapped trees and wires causing seven million dollars damage. |
SEPTEMBER 26TH, 1963 |
San Diego CA reached an all-time record high of 111 degrees. Los Angeles hit 109 degrees. |
SEPTEMBER 25TH, 1987 |
Hurricane Emily crossed the island of Bermuda during the early morning. Emily, moving northeast at 45 mph, produced wind gusts to 115 mph at Kindley Field. The thirty-five million dollars damage inflicted by Emily made it the worst hurricane to strike Bermuda since 1948. Parts of Michigan and Wisconsin experienced their first freeze of the autumn. Snow and sleet were reported in the Sheffield and Sutton areas of northeastern Vermont at midday. |
