1911 Atlantic hurricane season
Encyclopedia
The 1911 Atlantic hurricane season was relatively inactive, with only six known tropical cyclones forming in the Atlantic during the summer and fall. There were three suspected tropical depressions, including one that began the season in February and one that ended the season when it dissipated in December. Three storms intensified into hurricanes, two of which attained Category 2 status on the modern-day Saffir–Simpson Hurricane Scale. Storm data is largely based on the Atlantic hurricane database

 hurricane database (HURDAT) officially recognizes six tropical cyclones from the 1911 season. Only three attained hurricane status, with winds of 75 mph (120.7 km/h) or greater. The third hurricane of the season was the most intense storm, with a minimum central air pressure of 972 mbar (28.7 inHg). A week after its dissipation, another hurricane formed with wind speeds that matched the previous storm, but with unknown air pressure. Three weak tropical depressions developed and remained below tropical storm force; the first formed in February and the third in December. The first storm to reach tropical storm intensity developed on August 4, and the final tropical storm of the year dissipated on October 31.

The early 1900s lacked modern forecasting and documentation. The hurricane database from these years is sometimes found to be incomplete or incorrect, and new storms are continually being added as part of the ongoing Atlantic hurricane reanalysis

. The period from 1911 through 1914 was reanalyzed in 2005. Two previously unknown tropical cyclones were identified using records including historical weather maps and ship reports, and information on the known storms was amended and corrected. These storms are referred to simply by their number in chronological order, since tropical cyclones in the Atlantic Ocean were not given official names until much later.

, the depression became a tropical storm and turned northeastward. The storm lasted several more days until dissipating on August 11. The storm produced heavy rainfall on the Bermuda, but no gale-force winds were reported. The storm was unknown until the 2005 Atlantic hurricane database revision recognized it as a tropical storm.

Hurricane Two

As it approached the U.S. Gulf Coast, the cyclone attained maximum sustained winds estimated at 80 mph (130 km/h), corresponding to Category 1 status on the modern-day Saffir–Simpson Hurricane Scale. Pushing ashore near the Alabama–Florida border, it weakened over land and curved toward the west. On August 12, the storm drifted over Louisiana

The winds brought down telephone and telegraph wires, cutting off communication to outside areas for 24 hours. The city also suffered power failures on the night of August 11. Shipping suffered heavy losses, with many barges blown aground. The hurricane dispersed "immense quantities" of lumber being stored along the coast.

Hurricane Three

Over a week after the dissipation of the previous hurricane, the third storm of the season developed on August 23 and slowly tracked west-northwestward. After attaining hurricane status, the storm turned more towards the northwest, and several days later reached its peak wind speeds of 100 mph (155 km/h); a barometric pressure of 972 mbar (hPa) was reported.

, last reporting 94 mph (151.3 km/h), failed, and 4.9 in (124.5 mm) of precipitation fell over three days.

The storm raged for more than 36 hours, causing severe damage; the winds unroofed hundreds of buildings, demolished many houses and had an extensive impact on power and telephone services. Tides 10.6 ft (3.2 m) above normal left a "confused mass of wrecked vessels and damaged wharfs", according to a local forecaster in Charleston, while six navy torpedo boats were ripped from their moorings and blown ashore. In total, 17 people were killed in the hurricane, and property damage in Charleston was estimated at $1 million (1911 USD, $  USD).

Tropical Storm Five

The fifth official tropical cyclone of the year was also previously unknown until contemporary reassessments. It exhibited some hybrid characteristics, and may have qualified for subtropical cyclone

The storm's circulation center remained poorly defined throughout its course.

Tropical depressions

 of low pressure in the open Atlantic and progressed westward. Although a ship dubiously reported winds of over 50 mph (80.5 km/h) in association with the system, a lack of supporting evidence precludes its designation as a tropical storm. The cyclone dissipated by February 21. The second depression evolved from an extratropical cyclone

It persisted for three days as it meandered around the same general area before being absorbed by another non-tropical storm. The modern-day documentation of this system was also hindered by a lack of data. On December 11, the third tropical depression formed near the Turks and Caicos Islands
