the influence of a mid-level ridge to the north, Juliette strengthened, aided by a low wind shear environment. It became a hurricane the next day, and rapidly intensified to a Category 4 hurricane on September 23. A pinhole eye appeared on the 24th, and Juliette reached peak intensity on September 25 with winds and a minimum barometric pressure of 923 millibars. Juliette developed rare concentric eyewalls as it reached peak intensity, which persisted from September 24 to the 27th. On September 26, Juliette turned northward around a strong trough over the western United States and began to weaken. Passing just west of Cabo San Lucas on September 28 with winds, it made landfall near San Carlos as a minimal tropical storm two days later. Juliette crossed the Baja California Peninsula into Gulf of California as a tropical depression and dissipated over the far northern part of the gulf on October 3. Juliette dumped heavy rains on the Baja California Peninsula and in Sonora, where it caused two deaths. Its effects were especially hard on Cabo San Lucas, Baja California Sur, which was cut off from the outside world for a few days. The remnants of Juliette moved into the state of California, where they caused thunderstorms, rain, and some downed power lines. The total estimated cost of damage was $400 million (2001 USD; $ USD). Hurricane Kiko A tropical wave that led to the formation of Atlantic Hurricane Felix over the eastern Atlantic on September 7 also seems to have produced Kiko. This wave moved westward at low latitudes, crossing northern South America and Central America into the East Pacific from September 13 to 16. By September 17, cloudiness and showers increased near the Gulf of Tehuantepec. The area of disturbed weather moved westward for the next few days, without much increase in organization. On September 21, the system's cloud pattern became more consolidated, and curved bands of showers were evident. It is estimated that Tropical Depression Twelve-E had formed that day, at which time it was centered about southwest of the southern tip of Baja California. Located in an environment of easterly vertical shear, the system strengthened slowly. By September 22 the organization of the cloud pattern improved, and the cyclone strengthened into Tropical Storm Kiko. Kiko turned from a northwestward to a west-northwestward heading that day. Although some easterly shear continued to affect the system, very deep convection
