AUGUST 20TH, 1886-The town of Indianola TX was completely destroyed by a hurricane, and never rebuilt.
AUGUST 20TH, 1886 |
The town of Indianola TX was completely destroyed by a hurricane, and never rebuilt. |
AUGUST 20TH, 1910 |
The "big blow up" of forest fires finally came to an end in Idaho. A record dry August fueled 1736 fires which burned three million acres destroying six billion board feet of timber. The fires claimed the lives of 85 persons, 78 of which were fire fighters, and consumed the entire town of Wallace. The smoke spread a third of the way around the world producing some dark days in the U.S. and Canada. The forest fires prompted federal fire protection laws. |
AUGUST 19TH, 1788 |
A small but powerful hurricane inflicted great havoc upon forests along a narrow track from New Jersey to Maine. A similar storm track today would cause extreme disaster in the now populated area. |
AUGUST 19TH, 1969 |
'Never say die' Camille let loose a cloudburst in Virginia resulting in flash floods and landslides which killed 151 persons and cause 140 million dollars damage. Massies Hill VA received 27 inches of rain. |
AUGUST 18TH, 1983 |
Hurricane Alicia ravaged southeastern Texas. The hurricane caused more than three billion dollars property damage, making it one of the costliest hurricanes in the history of the U.S. Just thirteen persons were killed, but 1800 others were injured. The hurricane packed winds to 130 mph as it crossed Galveston Island, and spawned twenty-two tornadoes in less than 24 hours as it made landfall. |
AUGUST 18TH, 1779 |
Pioneer weather observer William Dunbar describes a hurricane's eye as it travels above New Orleans. |
AUGUST 17TH, 1915 |
A hurricane hit Galveston TX with wind gusts to 120 mph and a twelve foot storm surge. The storm claimed 275 lives, including forty-two on Galveston Island, with most deaths due to drowning. Of 250 homes built outside the seawall (which was constructed after the catastrophic hurricane of 1900), just ten percent were left standing. |
AUGUST 17TH, 1969 |
Camille, the second worst hurricane in U.S. history, smashed into the Mississippi coast. Winds gusted to 172 mph at Main Pass Block LA, and to 190 mph near Bay Saint Louis MS. The hurricane claimed 256 lives, and caused 1.3 billion dollars damage. Several ocean going ships were carried over seven miles inland by the hurricane. The hurricane produced winds to 200 mph, and a storm surge of 24.6 feet. Complete destruction occurred in some coastal areas near the eye of the hurricane. |
AUGUST 16TH, 1777 |
The Battle of Bennington, delayed a day by rain, was fought. The rain delayed British reinforcements, and allowed the Vermont Militia to arrive in time, enabling the Americans to win a victory by defeating two enemy forces, one at a time. |
AUGUST 16TH, 1909 |
A dry spell began in San Bernardino County of southern California that lasted until the 6th of May in 1912, a stretch of 994 days! Another dry spell, lasting 767 days, then began in October of 1912. |
AUGUST 15TH, 1967 |
The "sundance fire" in northern Idaho was started by lightning. Winds of 50 mph carried firebrands as much as ten miles in advance to ignite new fires, and as a result, the forest fire spread twenty miles across the Selkirk Mountains in just twelve hours, burning 56,000 acres. The heat of the fire produced whirlwinds of flame with winds up to 300 mph which flung giant trees about like matchsticks. |
