1985 Pacific hurricane season

The final two flights of the season were made on September 21 and 22 into Hurricane Terry while the storm was located off the west coast of the Baja California Peninsula.

[16] Although the watch was discontinued when Nele veered west, it later re-curved and struck the Northwestern Hawaiian Islands, giving boats a rough night.

[3] Waldo destroyed hundreds of homes in Sinaloa and later produced significant rainfall across the Southwestern United States and Great Plains.

[7] Andres headed west, and two days after formation, it reached its maximum intensity of 70 mph (110 km/h) while located south of the Baja California Peninsula.

However, due to colder sea surface temperatures and increasing vertical wind shear, Dolores quickly weakened, and by early on July 2, it was downgraded to a tropical storm.

Passing 50 mi (80 km) north of Socorro Island, Guillermo attained its maximum intensity of 60 mph (95 km/h) during the evening of July 9.

[3] The remnants of the storm brought light rainfall to the mountains and valleys of California, helping re-fill dry reservoirs and put out large fires.

Initially, the depression tracked northward due to weak southerly flow associated with an upper-level high centered near the southern tip of Baja California Sur.

The storm attained peak wind speed of 130 mph (210 km/h) while located roughly 600 mi (965 km) southwest of Cabo San Lucas.

[3] Intensifying further west than normal,[5] Ignacio reached winds of 70 mph (110 km/h) on July 22, roughly 24 hours after formation, and subsequently entered the CPHC's warning zone.

[21] The hurricane held peak intensity for several hours, however, an upper trough northwest of the Hawaiian Islands was gradually approaching Ignacio.

Subsequently, the environment was rapidly becoming less conductive as the trough induced increased southwesterly wind shear and introduced colder and drier air into Ignacio's circulation.

[5] Because of a strong trough was located northwest of Ignacio, many tropical cyclone forecast models predicted a more northerly track than what ultimately occurred.

Some heavy showers associated with the outer rainband's of the low fell on the windward slopes of the Big Island of Hawaii and Maui, where rainfall totals of 5–10 in (130–250 mm) were recorded.

After moving westward over sea surface temperatures of 84 °F (29 °C), the disturbance developed into Tropical Depression Fourteen at 1800 UTC on August 6, while centered about 460 mi (740 km) southwest of Acapulco.

While tracking across an area of sea surface temperatures of 81 °F (27 °C), the disturbance slowly intensified and the EPHC reported that the system had developed tropical depression at 1800 UTC on August 19.

However, hostile conditions caused the system to cease to exist as a tropical cyclone early on August 31 several hundred miles west-southwest of San Diego, California.

Turning southwest between an upper-level high over Baja California and a low near the southern coast of Mexico, the depression intensified into Tropical Storm Pauline.

The system crossed the International Date Line the next day, at which time the Joint Typhoon Warning Center (JTWC) took over monitoring responsibilities.

Initially disorganized due to strong wind shear counteracting the warm waters that it was in, satellite imagery on August 31 indicated that the thunderstorm activity had increased in the vicinity of the wave on.

Despite being situated over warm waters and in a low wind shear environment, further intensification was initially slow to occur as Rick was 800 mi (1,285 km) east of Pauline, with it not attaining hurricane status until September 6.

[7] On 1800 UTC September 14, Sandra weakened back into a tropical storm roughly 600 mi (970 km) west of the Baja California Peninsula.

The system turned northwest; subsequently, the depression was upgraded into Tropical Storm Terry 24 hours after formation approximately 300 mi (480 km) south of Acapulco.

[3] The hurricane at one point in time was predicted to make landfall in central Baja California and threaten San Diego;[32] however, this did not occur.

[36] In combination with a cold front, Waldo contributed to major flooding in Kansas that forced many rivers and creeks to overflow their banks.

In Kansas City, Waldo produced 1 ft (30 cm) of water on roads, but none of the nearby homes received extensive damage.

About 24 hours after the hurricane watch was issued, it was dropped as Nele moved away from the islands, alongside the cancellation of a high surf advisory.

However, increased wind shear from a trough, an elongated area of low pressure, took toll on the storm and it weakened on August 21 near the Johnston Atoll.

Over a month later, a weak disturbance located about 345 mi (555 km) southwest of the southern tip of Baja California Sur developed a circulation; the system was promptly classified as Tropical Depression Twenty-Five at 0600 UTC on November 21.

[44] Storms were named Kevin, Linda, Marty, Nora, Olaf, Rick, Sandra, Terry, Vivian, Waldo, and Xina for the first time in 1985.
