Hurricanes & Tropical Storms - September 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.


Note: This report catalogs recent tropical cyclones and places each basin's tropical cyclone activity in a climate-scale context. It is not updated in real time. Users seeking real time status and forecasts of tropical cyclones should visit The National Hurricane Center.

Atlantic Basin

The number of North Atlantic tropical cyclones during the month of September was below normal with only one cyclone reaching hurricane intensity in the month. On average, 2.5 cyclones reach hurricane strength at some point in September. For the season-to-date period, two cyclones have reached hurricane strength. On average, 4.8 hurricanes form in the North Atlantic from the start of the season to the end of September.

Hurricane Fred gained notoriety by becoming only the third major hurricane to be noted east of 35 degrees West in the tropical Atlantic Ocean. In 1926 there was an unnamed hurricane observed and more recently Hurricane Frances in 1980. Frances became a hurricane further east than Fred, but was not as powerful. HURSAT utilizes Google Earth by displaying 30-years worth of tropical cyclone satellite imagery in all basins. The infrared satellite loop of Frances shows how quickly the cyclone was able to organize and gain hurricane strength. Satellite imagery was not available prior to 1960, so it is possible more storms occurred but were not spotted. All averages are based on a 1979—2009 period.
