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.[nb 1] 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.

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.[1] As a result, the disturbance was classified as a tropical depression between the Greater Antilles and Bermuda at 1200 UTC on August 26.[2] Operationally, the storm was analyzed to have undergone tropical cyclogenesis on August 30.[3] However, a reanalysis of the storm conducted in 2012 found that the system was already organized prior.[1][4] In its initial stages, the depression remained weak,[2] with few ships reporting abnormally strong winds in association with the storm.[1] 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.[2] At 0600 UTC on August 30, the tropical storm strengthened further into the equivalent of a modern-day Category 1 hurricane,[2] roughly 225 mi (360 km) east of the Florida peninsula.[3] At the same time, the hurricane began to intensify and move quicker than it had previously.[2] 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).[1][3]

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.[2] Early on September 1,[3] the hurricane passed 85 mi (135 km) of Cape Hatteras, North Carolina,[1] before recurving towards the northeast and away from the coast.[3] 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;[1] 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.[5] 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.[2] 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).[1][3] 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.[2] 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.[1][3]

Preparations, impact, and aftermath

Rainfall totals in the United States

As the hurricane approached the United States East Coast on August 31, the United States Weather Bureau advised extreme caution to ships between Cape Hatteras and southern areas of New England.[6] Storm warnings were issued for coastal regions between Wilmington, North Carolina and the Virginia Capes. These warnings were later extended northward to the Delaware Breakwater. Strong winds exceeding gale-force were expected for much of the East Coast, particularly for Cape Hatteras.[7] On September 1, hurricane warnings were ordered for areas from Hatteras, North Carolina to Pamlico Sound, while previously issued storm warnings remained in place.[8] On September 2, gale warnings extended further north into Nantucket, Massachusetts.[9] In Norfolk, Virginia, city department heads were ordered to stand by for potential emergency duties. United States Coast Guard personnel were also dispatched along the North Carolina coast.[10] United States Navy personnel were detained in New London, Connecticut until the storm passed.[11] In Westhampton, New York, a mass evacuation occurred, involving 10,000 residences. Air traffic to and from Mitchel Air Force Base was cancelled, and 100 airplanes stationed at the base were fastened to the ground. Police and firemen evacuated a 50 mi (80 km) stretch of the Rhode Island coastline.[9] This included Roy Carpenter's Beach, where 1,000 families were forced to evacuate. In Narragansett Bay, boats were sent back to harbors or towed to shore.[12] The extensive precautionary measures undertaken occurred in part due to fears that the storm would cause similar effects to a destructive hurricane which swept through areas of New England two years prior.[9]

On September 1, the Venezuelan tanker Acosta relayed an SOS signal while near the hurricane 200 mi (320 km) southeast of the Frying Pan Shoals. United States Coast Guard stations in Norfolk, Virginia and Morehead City, North Carolina dispatched cutters to aid the ship.[8] Off of the East Coast, an offshoot of the hurricane resulted in the drownings of two people.[13] In the Mid-Atlantic states, the passing hurricane's outflow interacted with a cold front that had become quasi-stationary over the area. The cyclone's flow pattern enhanced the moisture environment over the region, resulting in locally heavy rainfall, particularly in New Jersey, where precipitation peaked at 24 in (610 mm) in Ewan in a nine-hour period on September 1.[14] This would make the hurricane the wettest tropical cyclone in state history.[15] Most of the rain was in western portions of the state, however, with minimal rainfall at the coast.[14] The floods caused small rivers to overflow, breaching dams.[14] An overflowed creek inundated parts of Lumberton Township, rendering 2,000 people homeless. Rail service between Philadelphia, Pennsylvania and areas of southern New Jersey was suspended as a result of washed out tracks.[9] Resulting damage to infrastructure totaled $4,000,000 in the southwestern quarter of New Jersey alone. Damage to roads in Burlington County amounted to $2,500,000.[16] In Camden County, damage was estimated at $1 million.[13] Four fatalities were reported as a result of the floods.[17] In Delaware, rainfall was comparatively less.[14] However, rough seas generated by the hurricane offshore caused $50,000 in damages and one death.[9] Further north, strong gusts were reported across New England. Winds of 60 mph (95 km/h) were recorded by a weather station in Nantucket. Peak winds in Massachusetts were estimated at 65 mph (100 km/h). In Eastport, Maine, winds of 45 mph (70 km/h) were reported.[1]

After the storm, New Jersey state health department investigators from Trenton were dispatched to study the possibility for an increase in typhoid fever in flooded areas.[18] In Woodbury, where the city pumping station was flooded, water was rationed. Gas service was also limited in Woodbury, Pedricktown, Penns Grove. As a result of a gas plant becoming inundated in Glassboro, electricity was rationalized in Hammonton, forcing residents to eat uncooked food. Police were forced to transport residents of Mount Holly to work via boat due to the high floodwaters.[13]

Despite making two separate landfalls in Atlantic Canada on September 2 and September 3, the hurricane caused minimal damage. Effects in Nova Scotia were limited to boating incidents. In Lake Milo, near Yarmouth, six yachts capsized due to the strong winds. In New Brunswick, damage was also minimal. A car accident associated with the storm injured a man near Barnesville.[19]
