1975 Atlantic hurricane season

Further intensification occurred and the storm reached its peak intensity with winds of 70 mph (110 km/h) and a barometric pressure of 981 mbar (981 hPa; 29.0 inHg) by July 2.

[3] The main effects from Amy were rough seas, reaching up to 15 ft (4.6 m) in height, that were felt from North Carolina to New Jersey, inflicting minor coastal flooding and beach erosion.

[9] Offshore North Carolina, a schooner carrying four people capsized on June 30, resulting in the death of the father of the other three crew members.

After wind shear decreased,[7] the wave managed to develop into a tropical depression on July 24 about 355 miles (571 km) northeast of the Turks and Caicos Islands.

It moved northwestward until early on July 26,[3] when an approaching cold front and associated trough caused the depression to turn northeastward.

[3] A weakening cold front and baroclinic forces created an environment favorable for intensifying,[7] allowing Blanche to become a Category 1 hurricane on July 27.

[3] In Atlantic Canada, the remnants of Blanche produced high winds gusts up to 70 mph (110 km/h), along with moderate rainfall, peaking at 3.1 in (79 mm) in Chatham, New Brunswick.

[12] Tropical Depression Six developed from a trough of low pressure in the northeastern Gulf of Mexico about 60 mi (97 km) southwest of Cape San Blas, Florida, on July 27.

[3][7] The depression moved west-northwestward and strengthened slightly to reach winds of 35 mph (56 km/h), but remained below tropical storm intensity and made landfall in eastern Louisiana.

[3][7] The depression moved west-southwestward and failed to intensify before crossing the Turks and Caicos Islands and making landfall along the northern coast in eastern Cuba on August 25.

Further strengthening occurred, with the storm peaking as a Category 3 hurricane with winds of 115 mph (185 km/h) and a minimum pressure of 963 mbar (28.4 inHg) early on August 31.

The precipitation ended an eight-month drought that was affecting inland portions of northern Mexico and decreasing the area's corn production.

Because the system was out of the authorized range of reconnaissance aircraft flights, satellites and ships were used to monitor the storm's intensity and tropical status.

[3] Based on the Dvorak technique, it is estimated that Doris peaked with maximum sustained winds of 110 mph (180 km/h) and a minimum barometric pressure of 965 mbar (28.5 inHg) shortly thereafter.

[7] On the following day, Doris quickly weakened to a tropical storm and transitioned into an extratropical cyclone about 830 mi (1,340 km) south-southeast of Cape Race, Newfoundland, around 06:00 UTC.

[3] The storm produced heavy rainfall throughout Puerto Rico and Hispaniola,[7] causing extensive flooding that left severe damage 59 fatalities.

[26] In that region, an additional 17 people died as a result of freshwater flooding from the post-tropical storm;[23] infrastructural and geological effects were comparable to those from Hurricane Agnes three years prior.

After detaching from the Intertropical Convergence Zone on September 18,[7] the wave quickly developed into a tropical depression about 575 mi (925 km) west of the Cabo Verde Islands.

[7] Although the system weakened to a Category 1 hurricane late on September 28, the storm reached its minimum barometric pressure of 977 mbar (28.9 inHg),[3] observed by a reconnaissance aircraft.

[7] Faye then curved eastward and lost tropical characteristics, becoming extratropical at 12:00 UTC on September 29, while situated northwest of Corvo Island in the Azores.

[3] Initially, the depression remained weak, but after encountering warm sea surface temperatures and low wind shear,[7] it strengthened into Tropical Storm Gladys on September 24.

[7] This subsequently allowed Gladys to rapidly intensify into a Category 4 hurricane, reaching maximum sustained winds of 140 mph (230 km/h) and a minimum barometric pressure of 939 mbar (27.7 inHg) on October 2.

Thereafter, Gladys began to weaken and passed very close to Cape Race, Newfoundland, before losing tropical characteristics on October 3 while situated about 385 mi (620 km) northeast of St.

[30] Heavy rains fell along the frontal boundary ahead of the system,[30] with a peak total of 9.01 in (229 mm) of precipitation observed in Aimwell, Louisiana.

[33] On October 27, gale warnings were issued for portions of the Outer Banks of North Carolina, and small craft advisories were posted for coastal areas from Georgia to Virginia.

[31] An extratropical low pressure system developed into a subtropical storm about 615 mi (990 km) east-southeast of Newfoundland, at 12:00 UTC on December 9.

[3][7] The storm moved rapidly southward and intensified, reaching maximum sustained winds of 70 mph (110 km/h) about 24 hours later,[3] based on observations from an unidentified ship.

The westernmost, designated Tropical Depression Nine, tracked generally westward and eventually dissipated near the Lesser Antilles on September 9.

Between November 9 and 10, reconnaissance missions into the depression found winds of 40 mph (64 km/h); however, the NHC did not upgrade it to a tropical storm, because weaken occurred shortly thereafter.

Over the following few days, the system gradually turned southward and made landfall in the southwestern edge of the Yucatán Peninsula on November 12, shortly before dissipating.
