This story is based on a press release from the World Meterological Organisation (WMO) Here is the text of the WMO Press release:
Global tropical cyclone activity was well below normal in 2010, except in the North Atlantic. A total of 65 tropical cyclones have been observed so far in 2010, of which 35 have reached hurricane/typhoon intensity as of 30 November. These are both well short of the long-term averages of 85 and 44 respectively. It is likely that the final total for the year will be the lowest since at least 1979.
Tropical cyclone activity was especially sparse in the North Pacific Ocean. Only 7 cyclones occurred in the Northeast Pacific and 14 in the Northwest Pacific (long-term averages 17 and 26 respectively). Both the Northeast and Northwest Pacific totals were the lowest on record for January-November. In contrast, the North Atlantic had a very active season with 19 named storms and 12 hurricanes, which is equal second highest behind the record of 15 set in 2005 (long-term averages 10 and 5 respectively).
The strongest tropical cyclone of the year was Supertyphoon Megi, which crossed the northern Philippines in October after reaching a minimum central pressure of 885 hPa, making it the strongest tropical cyclone in the world since 2005 and the strongest in the Northwest Pacific since 1984. Megi caused widespread damage to infrastructure and agriculture in the northern Philippines, Taiwan and Fujian province in China, but only limited casualties. Tomas (North Atlantic, November) reached category 2 intensity, but its associated rains contributed to the spread of a cholera epidemic in Haiti.
