The deadliest tornado outbreak in U.S. History occured on March 18, 1925. Seven tornados were spawned by the storm system that spread distruction from Alabama to Indiana. In all 740 people were killed in this outbreak. But there's one storm that named the outbreak, a mega tornado that crossed 3 states.
It was the strongest hurricane to hit the U.S. in nearly 34 years. Hurricane Camille struck the Mississippi Gulf Coast in 1969. It was only one of 2 catagory 5 storms to make landfall in the United States. It formed August 14 south of Cuba. Camille was a compact storm something that would eventually baffle forecasters due to its intensity.
The costliest hurricane in U.S. History formed like all tropical systems as a tropical depression on August 16. It formed out in the traditional breeding ground for hurricanes, near the Cape Verde islands. Four days later, it moved to the north of the Lesser Antillies in the Caribbean and stayed north of the rest of the islands. Andrew remained a minimal tropical storm untill the 22nd when it reached hurricane status. It was the first such hurricane to form from a tropical wave in 2 years.
Nearly 50 years ago, the nation was reeling from a series of seven tornados that moved through seven states. At least one huge tornado moved through a tri-state area and was the deadliest twister ever. A direct warning system was needed following that because the 1974 Super Outbreak overwhelmed those giving out warnings.
No doubt the flood of the century, rains began falling in the Upper Midwest in March of 1993 and continued into September. The Mississippi River Flood affected nine states, the Upper and Lower Mississippi Valley and parts of the Missouri River. This flood lasted months through the sweltering summer months. But it really started in late 1992 when the upper Midwest had unusually high rainfall.
The strongest storm to hit the east in the century. Superstorm 1993 began as a low pressure system that moved out of the Rockies to the Gulf where it exploded rapidly. This storm is remembered for being predictable almost a week before it happened.
