1914 Atlantic hurricane season
Encyclopedia
The 1914 Atlantic hurricane season was the least active Atlantic hurricane season on record, with only one known tropical storm
Tropical cyclone
A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor...

. Although hurricane season typically encompasses a much larger time-span, actual activity was confined to the middle of September. The only tropical cyclone of the year developed in the region of The Bahamas

. Thorough warnings before the storm prevented any major damage. The 1914 season is one of only two that did not produce any hurricanes. Due to the lack of modern technology, including satellite imagery, information is often sparse, and an additional tropical depression may have existed in late October.

Season summary

With only one official tropical cyclone, the 1914 season was the least active Atlantic hurricane season on record. It is one of only two Atlantic season without a storm of hurricane intensity (winds of 75 mph (120.7 km/h) or stronger), the other being the 1907 season
1907 Atlantic hurricane season
The 1907 Atlantic hurricane season ran through the summer and the first half of fall in 1907. The season was a very quiet with only five tropical storms forming, with none of them reaching hurricane strength. This feat has only been accomplished one other season, the 1914 season...

. The sole tropical storm's formation on September 14 represents the latest start to a hurricane season since officials records began in 1851.

Information on the 1914 season is chiefly based on data from the Atlantic hurricane database

 from 1911 through 1914 in 2005. Several changes, mostly of a minor nature, were made to the September tropical storm. Additionally, two other systems during the year were formally considered for inclusion into the hurricane database, one of which was deemed a possible tropical depression, but too weak to be classified a tropical storm. The other was assessed as a non-tropical system. The 2005 HURDAT reanalysis relied largely on historical weather maps and ship reports in place of modern technology, including satellite imagery. Since tropical cyclones in the Atlantic were not officially named until 1950, they are listed by their chronological number in older seasons.


Tropical Storm One

The first and only tropical storm of the season originated in a tropical wave

, as indicated by weather maps from September 13. The Atlantic hurricane database initially listed the system as a tropical cyclone by September 14, although the 2005 reanalysis concluded that a closed low pressure system had not yet developed. Maps from September 15 display a weak low north of The Bahamas; however, other observations place the new cyclone further south. Decreases in air pressure

Gradually intensifying, the tropical cyclone drifted northwest. By September 16 the storm had deepened to 995 millibars (29.4 inHg) according to weather maps, contrasting with other data portraying a much weaker storm. It was situated south of the Georgia coast later that day. While most tropical systems in the vicinity tend to continue northward along the Eastern Seaboard

, the cyclone curved westward and moved ashore near the Florida–Georgia state border after achieving a peak intensity with maximum sustained winds of 70 mph (112.7 km/h). It progressed inland over southern Georgia as it quickly weakened, and its intensity leveled off after around 1800 UTC on September 17. It skirted the northern Gulf of Mexico

, washing over the South Street Causeway. Winds from the storm dispersed large amounts of dead grass from marshes in the area. No significant damage was reported, however, due to thorough warnings before the cyclone. Aside from the date of formation, the 2005 reanalysis of the storm made only minor changes to its track and intensity records. Its peak intensity, however, was raised based on a ship report of higher winds.

Tropical depression

In addition to the September tropical storm, a possible depression that remained below tropical storm intensity developed in late October. On October 24, a broad area of low pressure was present over the western Gulf of Mexico and Caribbean Sea

 extending southward, had formed within the larger system and moved toward the east. Another center of low pressure formed in the northwestern Caribbean on October 25 and is considered a tropical depression in contemporary research. The depression had weak winds due to the light pressure gradient in the region and, at its peak, it had a minimum central pressure of 1004 mbar (29.6 inHg).

 to the north absorbed the tropical system. The next day, the extratropical system deteriorated into an open trough. Although the tropical low was reviewed for inclusion into the hurricane database as a tropical storm in 2005, it was deemed too weak.
