during August, including none during the first three weeks of August, a time that usually sees several storms. Activity picked up during the second half of the season, starting in September, when five named storms were observed, before decreasing to three and no storms in October and November respectively. On average, two to three tropical storms or hurricanes hit Mexico every year on the Pacific side. However, only one tropical cyclone, Hurricane Juliette, made landfall along the coast of Mexico in 2001. In addition, Adolph, Dalila, Ivo, and Lorena came close enough to land to require tropical cyclone warnings and watches. Systems Hurricane Adolph Hurricane Adolph originated from a tropical wave that left Africa on May 7, and was poorly organized. It was not until May 18 that the storm showed some signs of development in the Atlantic Ocean. On, May 22 the wave crossed over, and on May 25 it intensified into Tropical Depression One-E, about south-southwest of Acapulco, Mexico. The system, after drifting a while, intensified into Tropical Storm Adolph the next day. Later, on May 27 Adolph was upgraded to a hurricane. Intensifying into a hurricane, Adolph rapidly intensified, and reached to Category 4 strength on May 28. Two days after, Adolph went under an eyewall replacement cycle, and weakened to a hurricane, which is minimal category 3 intensity. This trend of weakening continued, and deteriorated into a tropical storm. Passing over cooler waters, and stable air, Adolph dissipated on June 1. Tropical Storm Barbara A tropical wave that moved off the coast of Africa on June 1. The wave eventually entered the Pacific Ocean on June 10, though no further organization occurred until June 18. The system slowly organized further over the next two days, and became Tropical Depression Two-E early on June 20. Although the depression remained poorly organized, it was upgraded to Tropical Storm Barbara. At 12:00 UTC on June 21, the storm attained its peak intensity with maximum sustained winds of and a minimum barometric pressure of . Shortly thereafter, Barbara began encountering unfavorable conditions, such higher wind shear and cooler sea surface temperatures. It weakened to a tropical depression at 18:00 UTC on June 26, while crossing 140°W into the Central Pacific Hurricane Center's area of responsibility. The depression passed north of the Hawaiian Islands on June 25, then weakened to an easterly wave to the northwest of Kauai on June 26.
