1899: Hurricane San Ciriaco set many records on its path. Killing nearly 3,500 people in Puerto Rico, it was the deadliest hurricane to hit the island and the strongest at the time, until 30 years later when the island was affected by the Hurricane San Felipe Segundo, a Category 5 hurricane, in 1928. San Ciriaco is also the longest lasting Atlantic hurricane in recorded history, lasting for 28 days. On August 17, the hurricane turned back to the northwest and made landfall near Hatteras, North Carolina on the following day. San Ciriaco remains the strongest hurricane to make landfall on the Outer Banks since 1899.
1946: An estimated F4 tornado killed 11 people and injured 100 others in the Mankato, Minnesota area around 6:52 PM. The deaths and most of the injuries occurred in the complete destruction of the 26 cabins at the Green Gables tourist camp, 3 miles southwest of Mankato. A 27-ton road grader was reportedly hurled about 100 feet. Another tornado an hour later destroys downtown Wells, Minnesota.
