The 1943 Atlantic hurricane season marked the first deliberate reconnaissance aircraft flights into tropical cyclones. The season officially lasted from June 16 to October 31, which was, at the time, considered the most likely period for tropical cyclone formation in the Atlantic Ocean.[1][nb 1] A total of ten storms from 1943 are listed in the Atlantic hurricane database, and an eleventh system that affected Florida and Georgia has been identified as a probable tropical depression. The first system of the year, dubbed the "Surprise hurricane", caused severe damage throughout Texas and Louisiana in June, partially because information about its approach was censored in the fray of World War II; the storm caused 19 deaths and $17 million in damage.[nb 2] A major hurricane in mid-August produced hurricane-force winds in Bermuda,[nb 3] and several other tropical cyclones throughout the year resulted in strong winds there. In September, a hurricane impacted the western Gulf Coast of the United States, then a tropical storm struck the Mid-Atlantic. The two storms resulted in $419,000 and $20,000 in damage, respectively; one death was attributed to the latter system. In mid-October, a strong hurricane resulted in flooding and damage to crops throughout the Caribbean; after becoming post-tropical, it contributed to moderate impacts across Nova Scotia.
The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 94 units,[4] above the 1931–1943 average of 91.2.[5] ACE is a metric used to express the energy used by a tropical cyclone during its lifetime. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated at six-hour increments in which specific tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity. Thus, tropical depressions are not included here.[4]
