Northeast Pacific Basin
According to the National Hurricane Center, on average (1966-96) there are approximately six named systems (four tropical storms and two hurricanes) to form in the Eastern Pacific by August 1st. For the year-to-date period, there have been five named storms to form which is below the long-term averages of six tropical storms and three hurricanes. |

Tropical Storm Blanca formed off the coast of Central Mexico on July 6th and traveled northwestward into favorable conditions that allowed the storm to quickly intensify. Later that day Blanca's wind speed was measured at 50 mph (85 km/h) as this was also its maximum wind intensity. The tropical storm was short lived as it encountered cooler waters and an environment that was not conducive for further intensification. By the early morning hours of July 9th, the National Hurricane Center (NHC) issued the last statement for Tropical Storm Blanca. More information on Tropical Storm Blanca is available from the NOAA National Hurricane Center. |

On July 10th, the Eastern Pacific's second hurricane formed approximately 900 miles (1448 km) south of Baja California. Hurricane Carlos was steered westward by a deep layer ridge and reached maximum intensities of 105 mph (165 km/h) and 972 mb. The NHC expected Carlos to continue strengthening due to the low wind shear and warm waters that were ahead of the storm — however, the eye of Carlos filled in and the deep convective activity contracted. The cyclone was downgraded to a tropical storm on the afternoon of the 12th, but re-strengthen to a hurricane in the early morning hours of the 14th. During the next day, the cloud tops began to warm and the eye was no longer visible which prompted the NHC to once again downgrade the cyclone to a tropical storm. The last advisory was posted on the afternoon of the 16th. More information on Hurricane Carlos is available from the NOAA National Hurricane Center. |

In the middle of July, Tropical Storm Dolores formed from an area of low pressure south of the tip of Baja California. For a short period of time, the storm displayed deep convection, but was short lived due to southwesterly wind shear associated with an upper level trough that was positioned to the northwest. On July 17th, the NHC issued its last advisory for Dolores. Its maximum winds were recorded to be 50 mph (85 km/h) and its lowest pressure was 998 mb. More information on Tropical Storm Dolores is available from the NOAA National Hurricane Center. |
