1965 Pacific hurricane season

The Pacific hurricane season 1965 officially began on May 15, 1965 at the Eastern Pacific Ocean and on 1 June 1965 at the Central Pacific. It lasted until 30 November 1965. These data conventionally delimit the period of the year in which usually are the most tropical cyclones in the northeastern Pacific. In the season of 1965 a total of ten Systene were observed, one of which with the exception of Hurricane Emily reached no hurricane strength. The most significant storm of the season was Tropical Storm Hazel, since its impact in Mexico, six people were killed.

Storms

Tropical Storm Victoria

On June 4, was formed 945 km southwest of Acapulco, Mexico, the first tropical system of the season and received a day later in the intensification into a tropical storm the name Victoria. At this time the storm reached its greatest intensity with sustained one-minute winds of 85 km / h This strength is retained in the storm, while he moved to the Northwest. Early on June 7 to Victoria weakened to a tropical depression, which broke up six hours later. Victoria remained of their existence on the open sea during the entire time.

Tropical Storm Wallie

Early in the morning of June 17 was formed 300 km west of Puerto Angel, Mexico, a tropical depression. This system intensified into a tropical storm with a one-minute peak sustained wind speed of 85 km / h Wallie moved in a northwesterly direction and weakened early on June 18, shortly before the Mexican coast to a low pressure area off. The remnant low moved near Zihuatanejo on the Mexican coast. Later in the day, the system broke up.

The storm damage in Mexico has been described as the most extensive within eight years and estimates the damage to several thousand dollars, but an exact amount of damage is not known. In connection with the storm no loss of life were reported.

Tropical Storm Ava

Early on June 29, was identified about 860 km south of Cabo San Lucas on the southern tip of Baja California, Mexico, a tropical storm. This was given the name Ava. At this time there was the storm with wind speeds of 85 km / h in its peak phase, but within the next 24 hours, the system weakened to a tropical depression. Late on June 30, the storm reached again the status of a tropical storm. At this point, Ava moved westward, but this slightly more to the north and later to the south. On July 3, Ava lost again in intensity. Early on July 5, the low pressure area disbanded. Ava stayed during their existence at sea, so that no accidents have been reported.

Tropical Storm Bernice

On June 30 was formed Tropical Storm Bernice. At this time the system was about 445 km south of Puerto Angel, Mexico. During the next days the storm moved northeastward and reached a peak wind speed of 85 km / h On June 5, ended the northbound train movement and Bernice turned east. On 8 July, the tropical storm broke up without ever having reached the country.

Tropical Storm Claudia

During the afternoon of August 7 was formed about 240 km southwest of Cabo San Lucas, a tropical depression. On August 8 the system to Tropical Storm Claudia reinforced. At the time of the Claudia with wind speeds of 85 km / h, highest intensity reached, the storm began to curve to the north. The storm kept during this turning motion until August 10 at its peak intensity, then the wind speed slightly decreased and the storm warnings were discontinued .. The storm had no effects on land.

Tropical Storm Doreen

Late on 19 August, Tropical Storm Doreen was first spotted on a TIROS satellite image. The next day the ship San Juan Prospector wind speeds of 40 knots reported ( about 70 km / h) and a barometric pressure of 975 mbar ( hPa). At this time Doreen moved with a forward speed of ten knots to the northwest. On August 21, Doreen changed the direction of pull on a westerly course, but returned a day later back to the original direction of pull. On August 22 announced the Kyoyu Maru, which was located just north of the storm center, wind speeds of 60 knots. During the following days the storm struck a slight curve to the north, then, however, was slow and moved to the southwest. On August 30, Doreen crossed in the central Pacific, where the storm broke up the next morning. During the existence of the system 13 vessels reported wind data to Doreen, but reports of damage to property was not registered.

Hurricane Emily

On August 30, in formation of a moderate tropical storm. This intensified slowly and was on August 31 at 12:00 UTC the first and only hurricane hurricane season 1965. Emily lost on the way northward to power. On September 3, at 00:00 UTC, Emily weakened to a tropical depression. In this intensity the system met on 6 September to Lower California. Emily was operationally as the first storm after many years, from which emanated a potential threat for Southern California. He approached to the south of the state, as the SEALAB II project was carried out before La Jolla, California. There was therefore temporarily fears that would leave by the waves the Berkone, a support vessel for the experiment, the place was anchored to the SEALAB II and therefore a termination of the project would be necessary. However, the rainfall from the storm were not overly; in some areas they reached about 25 mm.

Tropical Storm Florence

The tropical storm Florence was formed on 8 September as a tropical depression. After 24 hours, the system intensified to a tropical storm and was named Florence. This reached its greatest intensity at the time with wind speeds of 80 km / hr. On 11 September, Florence weakened suddenly. After he had maintained its intensity for a few days, the system was declared on September 15 as resolved. Florence remained at sea, and in the context of the storm no property damage or personal injuries were reported.

Tropical Storm Glenda

The tropical storm Glenda was formed on September 13 and maintained its intensity in a one-minute sustained wind speed over nine days away before the storm warnings were discontinued.

Tropical Storm Hazel

Hazel evolved from a northward pulling disorder originating southeast of Socorro Island. After Hazel reached the strength of a tropical storm, the storm turned east- north-east direction, which was confirmed by the report of a ship. The storm came near Mazatlan on 26 September about the country and quickly became extratropical. Six people died from the effects of the storm and thousands were left homeless. The fishing fleet of shrimp from Mazatlan who is treading a substantial part of the local economy, was badly damaged. In the south of Sinaloa more than 20,000 hectares were destroyed acreage for cotton, corn and sorghum. At least 50 boats and smaller vessels in the ports went under or were damaged. The damage to property was a total of 10 million U.S. dollars ( 1965 USD 76.7 million in today's prices ) is estimated. Hazel was thus the most serious tropical cyclone of the Pacific hurricane season.

Chronological overview of the season

Accumulated Cyclone Energy (ACE )

The Accumulated Cyclone Energy (ACE ) is a measure of the activity of the hurricane season. It is determined in the one-minute continuous wind speed of a storm is squared and added together, provided that the wind speed at least equal to that of a tropical storm. This Sume is finally divided by 104. Tropical Cyclones and subtropical systems are not counted.
