Myles’ Blog: Last day of Hurricane Season, 2012

Posted on: 10:00 am, November 30, 2012, by , updated on: 10:55am, November 30, 2012

November 30 marks the end of the 2012 Atlantic Hurricane season. This season produced 19 tropical depressions, 19 tropical storms, 10 hurricanes and one major hurricane.  The first storm of the season formed on May 19th and later became Tropical Storm Alberto. The last storm dissipated on October 31st as the leftovers of Hurricane Sandy. Here is a look at the entire 2012 season from “the top, down”. This animation shows all of the GOES East satellite imagery from June 1 to November 28th.

An interesting aspect of the season was its early start, with two tropical storms (Alberto and Beryl) developing before the season officially began. Also, this is the seventh consecutive year that no major hurricanes have hit the United States. The only major hurricane this season was Hurricane Michael, a Category 3 storm that stayed over the open Atlantic.

How did 2012 compare to the averages? The number of named storms is well above the average of 12. The number of hurricanes is also above the average of six, but the number of major hurricanes is below the average of three. Based on the combined number, intensity, and duration of all tropical storms and hurricanes, NOAA classifies the season as “above-normal.”

How did the long range forecasts perform? Let’s start with the popular Colorado State University forecast from June 1st; 13 named storms, 5 hurricanes, and 2 major hurricanes. The Florida State University forecast from May 30th: 13 named storms, and 7 hurricanes. The National Oceanic and Atmospheric Administration (NOAA) from August 9th; 12-17 named storms, 5-8 hurricanes, and 2-3 major hurricanes.

“This year proved that it’s wrong to think that only major hurricanes can ruin lives and impact local economies,” said Laura Furgione, acting director of NOAA’s National Weather Service. “We are hopeful that after the 2012 hurricane season, more families and businesses all along the Atlantic and Gulf Coasts
