1981 Pacific Hurricane Season - Seasonal Summary

Seasonal Summary

There was an absence in storm activity across the Central Pacific Hurricane Center's area of responsibility, as no storms developed in the basin. However, two tropical cyclones from the eastern Pacific, Greg and Jova, entered the central Pacific, the latter entering as a hurricane. The season produced fifteen named storms and eight hurricanes; both of these numbers were equal to the average. The season's one major hurricane, a storm with winds of at least 111 mph (179 km/h), was below the average of three. There are also at least two tropical depressions that did not strengthen into tropical storms. Six tropical cyclones made landfall in Mexico. First, Tropical Storm Adrian made landfall 240 mi (390 km) east-southeast of Acapulco, but did not cause any damage. Afterwards, Tropical Storm Irwin made landfall in Baja California Sur, but similarly to Adrian, did not cause any damage. Tropical Storm Knut later made landfall near Mazatlan with winds equivalent to a minimal tropical storm, but no deaths or damage was reported. Tropical Storm Lidia struck about 23 mi (37 km) south of Los Mochis on October 8, with winds of 45 mph (75 km/h). Heavy rainfall associated with the cyclone caused moderate damage in northwestern Mexico, and at least seventy-three deaths can be attributed to the storm.On May 30, an area of intense shower and thunderstorm activity located 270 mi (430 km) south of the Mexican coastline. The second to strike the area in 10 days, Norma was absorbed by a frontal system on October 14. The combined entity produced heavy rainfall and severe weather across Texas, which subsequently led to severe crop damage. The final storm to make landfall on Mexico during the 1981 season was Hurricane Otis. Intensifying into a hurricane by October 26, the hurricane brushed the coast of Jalisco before making landfall near Mazatlan at hurricane intensity on October 30. Otis was the second of two hurricanes to make landfall in the country this season.
