Hurricanes & Tropical Storms - August 2009


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.

Atlantic Basin

The year-to-date North Atlantic tropical cyclone total is four. All four storms occurred during the month of August, which is slightly above the average of 3.2. On average, by the end of August, the Northern Atlantic harvests 5.1 named storms and the yearly average is 12.1. All averages are based on a 1979—2009 period.

The low year-to-date tropical cyclones could be the result of a variety of contributing factors, including El Nino. It has been documented that the warming of the Eastern Pacific Ocean can increase the vertical wind shear in the Northern Atlantic, thus suppressing tropical cyclone activity. The graphs above help illustrate these findings. According to the Climate Prediction Center, recent strong El Nino episodes have occurred in 1982—83, 1991—92, and 1997—98.

Northeast Pacific Basin

August 2009, eight named storms spawned in the Eastern North Pacific (ENP) resulting in one of the most active Augusts on record. On average, 3.8 tropical cyclones form in the ENP during August and 2.2 of those became hurricanes. For the year-to-date period, there have been 13 named storms to form, five of which went on to become hurricanes. On average, there are typically ten named storms to form by the end of August and the annual average is 15.4. The 1992 ENP season was the most active as 27 named storms formed. All averages are based on a 1979—2009 period. The 2009 ENP season officially began on May 15th and ends November 30th.
