1852 Atlantic hurricane season

Category 3 hurricane (SSHWS)
Duration	August 19 – August 30
Peak intensity	115 mph (185 km/h) (1-min); 961 mbar (hPa)

The Great Mobile Hurricane of 1852 was the first tropical cyclone of the year. It was first observed on August 19 about 140 mi (230 km) north of Puerto Rico. It moved on a west-northwest motion before passing through the Bahamas as it attained hurricane status on August 20. After paralleling the northern coast of Cuba, the storm passed between the Dry Tortugas and Key West, Florida on August 22, and two days later it is estimated the hurricane attained peak winds of 115 mph (185 km/h). The storm slowed on August 25 before turning northward, and early on August 26 it made landfall near Pascagoula, Mississippi at peak strength, and the hurricane rapidly weakened to tropical storm status as it accelerated east-northeastward. On August 28 it emerged into the Atlantic Ocean from South Carolina, and after turning to the northeast, it was last observed on August 30 about 130 mi (210 km) southeast of Cape Cod.[4]

In the Florida Keys, rough waves forced several ships ashore, leaving some damaged.[5] Strong waves created four new channels in the Chandeleur Islands, and the storm's passage also destroyed the island lighthouse; the three keepers were found three days later. Two schooners were also washed ashore along Cat Island.[6] The hurricane produced an estimated storm tide of 12 feet (3.7 m) in Mobile, Alabama,[4] where strong winds damaged much of the city, leaving the majority of the houses destroyed. Trees were downed up to 30 miles (48 km) inland,[7] and coastal areas were flooded. Damage along the coastline was estimated at $1 million (1852 USD, $26 million 2008 USD), and several people died.[8] While crossing the southeastern United States, the storm brought light rainfall but moderately strong winds; in Charleston, South Carolina, the storm destroyed several bridges and crop fields.[4][9]

Category 1 hurricane (SSHWS)
Duration	September 5 – September 6
Peak intensity	80 mph (130 km/h) (1-min);

Hurricane San Lorenzo of 1852

Early on September 5, a hurricane was first observed about 65 mi (105 km) southeast of Christiansted in the Danish Virgin Islands.[1] One meteorologist assessed the hurricane as being located near Antigua on September 3.[2] Tracking steadily west-northwestward, it quickly moved ashore near Ponce, Puerto Rico with winds estimated at 80 mph (130 km/h). After crossing southwestern Puerto Rico, the hurricane emerged into the Mona Passage as a tropical storm. Late on September 5 it made landfall on eastern Dominican Republic; it quickly weakened over Hispaniola, dissipating on September 6 over the northwestern portion of the island.[1] An assessment by scholar Michael Chenoweth in 2006 indicated this storm was the same as the next hurricane, with it continuing northwestward and ultimately reaching the Gulf of Mexico.[2] Due to not being considered the same cyclone in the official hurricane database,[1] this hurricane and the following hurricane are listed separately.[4] There, the passage of the storm caused severe flooding, which destroyed large quantities of crops and damaged several roads. Storm damage was heaviest between Guayanilla and Mayagüez.[10] More than 100 people were killed in Puerto Rico,[11] many of whom died due to flooding.[10]

Category 1 hurricane (SSHWS)
Duration	September 9 – September 13
Peak intensity	80 mph (130 km/h) (1-min); 985 mbar (hPa)

A hurricane was located in the central Gulf of Mexico on September 9,[1] potentially the same hurricane as the previous storm.[2] It tracked generally eastward toward the coast of Florida, with its hurricane intensity estimation based on two ship reports. At about 0000 UTC on September 12, it moved ashore near Clearwater, Florida as a minimal hurricane, with an estimated minimum barometric central pressure of 985 mbar. Accelerating east-northeastward while crossing the state, the cyclone emerged into the Atlantic Ocean as a weakened tropical storm before regaining hurricane status on September 13. Later that day, it was last observed about 250 mi (400 km) east-southeast of Cape Hatteras.[1]

A post in Fort Meade, Florida reported at least 0.55 in (14 mm) of rainfall during the storm's passage. The hurricane was considered "violent", and gusts were estimated to have reached hurricane force.[4] Rough seas and strong easterly winds beached a vessel near St. Augustine.[12][13]

Category 1 hurricane (SSHWS)
Duration	September 22 – September 30
Peak intensity	90 mph (150 km/h) (1-min);

On September 22, a tropical storm was located about 200 mi (320 km) east of Guadeloupe. With a steady west-northwest path, the storm moved across the northern Lesser Antilles on September 23, during which it intensified into a hurricane. It passed a short distance north of Puerto Rico and the Dominican Republic as it reached its peak intensity of 90 mph (150 km). Late on September 26 the hurricane turned northwestward, bringing it through the Turks and Caicos Islands and eastern Bahamas. Recurving north-northeastward, the cyclone moved into open waters, and was last classified as a tropical cyclone on September 30 about 390 mi (630 km) east of Cape Hatteras.[1] However, one hurricane researcher assessed the hurricane as lasting until October 3, with the cyclone turning eastward and dissipating near the Azores.[2]

Category 2 hurricane (SSHWS)
Duration	October 6 – October 11
Peak intensity	105 mph (165 km/h) (1-min); 969 mbar (hPa)

A moderately strong hurricane with winds of 105 mph (169 km/h) was first spotted on October 6 east of Jamaica. Passing a short distance south of the island, the hurricane tracked northwestward and brushed the Yucatán Peninsula before turning north-northeastward into the Gulf of Mexico.[1] Late on October 9, it made landfall a short distance east of Apalachicola, Florida at peak winds with an estimated pressure of 969 mbar.[14] Rapidly weakening to tropical storm status, the cyclone continued northeastward and emerged into the Atlantic Ocean from North Carolina on October 11. Later that day, it was last observed about 250 mi (400 km) southeast of Cape Cod.[1]

Heavy damage was reported in Jamaica. Upon making landfall in Florida, the hurricane produced a 7 ft (2.1 m) storm tide, and in Georgia, hurricane-force winds extended into the southwestern portion of the state,[1] while tropical storm force winds occurred along the coastline. In the state, moderate winds damaged trees and roofs, though the destruction was less than anticipated.[12]
