1940 New England hurricane : ウィキペディア英語版 | 1940 New England hurricane
The 1940 New England hurricane moved off of the U.S. East Coast and Atlantic Canada in August and September 1940, producing strong winds and torrential rainfall. The fourth tropical cyclone and third hurricane of the season, the storm originated from a well-defined low-pressure area in the open Atlantic Ocean on August 26. Moving slowly in a general west-northwest motion, the disturbance intensified, reaching tropical storm strength on August 28 and subsequently hurricane intensity on August 30. The hurricane passed within 85 mi (135 km) of Cape Hatteras before recurving towards the northeast. The hurricane continued to intensify, and reached peak intensity as a Category 2 hurricane with maximum sustained winds of 110 mph (175 km/h) and a minimum barometric pressure of 961 mbar (hPa; 28.38 inHg), though these statistical peaks were achieved at different times on September 2. Afterwards, the hurricane began a weakening trend as it proceeded northeastward, and had degenerated into a tropical storm by the time it made its first landfall on Nova Scotia later that day. The storm transitioned into an extratropical cyclone the next day while making another landfall on New Brunswick. The extratropical remnants persisted into Quebec before merging with a larger extratropical system late on September 3. Despite not making landfall on the United States, the hurricane caused widespread damage. Extensive precautionary measures were undertaken across the coast, particularly in New England. The heightened precautions were due in part to fears that effects from the storm would be similar to that of a devastating hurricane that struck the region two years prior. Most of the damage associated with the hurricane occurred in New Jersey, where the combination of moisture from the hurricane and a stationary front produced record rainfall, peaking at 24 in (610 mm) in the town of Ewan. This would make the storm the wettest in state history. The resultant floods damaged infrastructure, mostly to road networks. Damage in the state amounted to $4 million. Farther north in New England, strong winds were reported, though damage remained minimal. Although the storm made two landfalls in Atlantic Canada, damage too was minimal, and was limited to several boating incidents caused by strong waves. Overall, the hurricane caused seven fatalities. ==Meteorological history==
The origins of the hurricane can be traced to a compact and slow-moving low-pressure area in the open Atlantic Ocean in late August 1940. As the system progressed in a west-northwest direction, its center of circulation became more organized. As a result, the disturbance was classified as a tropical depression between the Greater Antilles and Bermuda at 1200 UTC on August 26. Operationally, the storm was analyzed to have undergone tropical cyclogenesis on August 30. However, a reanalysis of the storm conducted in 2012 found that the system was already organized prior.〔 In its initial stages, the depression remained weak, with few ships reporting abnormally strong winds in association with the storm.〔 Continuing in a slow west-northwest movement, the disturbance gradually intensified, and was analyzed to have attained tropical storm intensity by 1800 UTC on August 28. At 0600 UTC on August 30, the tropical storm strengthened further into the equivalent of a modern-day Category 1 hurricane, roughly 225 mi (360 km) east of the Florida peninsula.〔 At the same time, the hurricane began to intensify and move quicker than it had previously. Later that day, a ship within the periphery of the storm reported winds of 60 mph (95 km/h) and a barometric pressure of 979 mbar (hPa; 28.90 inHg).〔〔 At 1200 UTC on September 1, the hurricane attained modern-day Category 2 intensity. Ships continued to report strong winds and low pressures associated with the storm. Early on September 1,〔 the hurricane passed 85 mi (135 km) of Cape Hatteras, North Carolina,〔 before recurving towards the northeast and away from the coast.〔 That same day, two ships reported hurricane-force winds. At 0200 UTC on September 2, the American steamboat ''Franklin K. Lane'' reported a barometric pressure of 965 mbar (hPa; 28.50 inHg) while located within the hurricane's radius of maximum wind;〔 this would be the lowest pressure measured in association with the tropical cyclone and the lowest measured in the entire North Atlantic Ocean in September 1940. Based on the ship observation, the storm was analyzed to have reached peak intensity on September 2 with maximum sustained winds of 105 mph (165 km/h) and a minimum central pressure of 961 mbar (hPa; 28.38 inHg). However, stronger winds of 110 mph (175 km/h) were analyzed to have been present in the hurricane earlier. As it traversed though more northerly latitudes, the storm began to gradually weaken. The storm made landfall slightly northwest of Yarmouth, Nova Scotia at 2100 UTC later on September 2 as a tropical storm with winds of 70 mph (110 km/h).〔〔 After quickly passing over Nova Scotia, the weakening tropical storm transitioned into an extratropical storm over the Bay of Fundy at 0000 UTC on September 3. At the same time, the cyclone made a second landfall on New Brunswick as a slightly weaker storm with winds of 65 mph (100 km/h). The extratropical system progressed over the Gulf of Saint Lawrence before it was absorbed by a larger extratropical storm at 1800 UTC later that day in Quebec just north of Anticosti Island.〔〔
