Hurricane experts in Texas say roughly every 30 years the circulation of salty water flowing from the Earth’s poles to the tropics and back again undergoes a cooling change where storms are born. From 1965 to 1995, a cool cycle resulted in little activity. The nation’s deadliest disaster was in 1900 when a hurricane struck Galveston. Storm surge caused 8,000 to 12,000 deaths. Other storms include the “Atlantic-Gulf Hurricane of 1919” in Corpus Christi, causing 900 deaths. On this date in 1928, 1,836 died from a lake surge following the Okeechobee hurricane. The “Florida Keys-Labor Day Hurricane of 1935” killed 408 and in 1944, the “Great Atlantic Hurricane” sank a Navy destroyer and minesweeper and two Coast Guard cutters. Hurricane Carol caused $461 million in damage in 1954. Fastcast: Warmer.
