Hurricanes & Tropical Storms - October 2006


NCDC transitioned to the nClimDiv dataset on Thursday, March 13, 2014. This was coincident with the release of the February 2014 monthly monitoring report. For details on this transition, please visit our public FTP site and our U.S. Climate Divisional Database site.

Pacific Basin

Two tropical storms and one hurricane formed in the East Pacific during October. Hurricane Paul was a strong category 2 storm before it weakened at the end of the month. Each of these storms is summarized below.

On the 8th, a tropical depression formed in the northeast Pacific and strengthened into Tropical Storm Norman the next day. Strong wind shear and cool sea surface temperatures hindered further development. The storm strength fluctuated over the next several days before dissipating on the 15th. At the peak of the storm, winds were approximately 45 kt (50 mph) and minimum central pressure was 1000 millibars (29.53 inches of mercury). The ACE value for Norman was 0.8850 x 104 kt2. More information on Norman is available from the NOAA National Hurricane Center.

Tropical Storm Olivia formed to the southwest of Tropical Storm Norman on the 9th. Assisted by deep convection, the storm reached peak intensity of 40 kt (45 mph) and had a minimum central pressure of 1000 millibars (29.53 inches of mercury) on the 10th. Wind shear and cooler ocean temperatures quickly weakened the storm and the remnant low pressure merged with the weakening Tropical Storm Norman on the 12th. The ACE value for Olivia was 0.4800 x 104 kt2. More information on Olivia is available from the NOAA National Hurricane Center.

On the 21st, an area of disturbed weather moved into an environment of warmer water and decreasing wind shear about 265 miles south-southwest of Manzanillo, Mexico. Within two days, this disturbance became Hurricane Paul and reached peak intensity of 110 mph (95 kt), a strong category 2 storm, later in the same day. The storm weakened as it moved into a region of stronger wind shear. Paul passed just south of the tip of Baja California as a tropical storm and continued to weaken as it approached the Mexican coast. By landfall near La Reforma in northwestern Sinaloa, the storm was merely a tropical depression. Minimal central pressure at the peak of the storm was 965 mb (28.95 inches of mercury). The ACE value for Paul was 6.4825 x 104 kt2. More information on Paul is available from the NOAA National Hurricane Center.
