On November 30, 2013, the National Hurricane Center in Miami, Florida, published its monthly Tropical Weather Summary for November 2013 (available online at http://www.nhc.noaa.gov/text/MIATWSAT.shtml). In the Atlantic Basin (North Atlantic, Caribbean Sea, and Gulf of Mexico), one tropical storm formed: Tropical Storm Melissa. The Hurricane Center’s report noted that on average a named tropical storm has formed in November about three out of every four years during the period of record.
The Hurricane Center’s November 30 report also included a summary of the entire Atlantic tropical storm season (June 1-November 30). Thirteen named storms, including two hurricanes, occurred. The annual average seen during the 30-year period 1981-2010 is 12 named storms and six hurricanes. No “major” hurricanes (Category 3 or above) occurred in 2013, and this is below the annual average of three for the 30-year period. The report also noted that the “accumulated cyclone energy” for 2013—combining strength and duration of storms—was about 67percent belowthe 1981-2010 average, and was the lowest since 1994.
Here is the Hurricane Center’s list of all tropical storms during the 2013 Atlantic season (H = hurricane; MH = major hurricane; TD = tropical depression; TS = tropical storm):
Name – Dates – Maximum Wind Speed (mph)
TS Andrea – Jun. 5-7 – 65 mph

TS Chantal – Jul. 8-10 – 65 mph
TS Dorian – Jul. 23-Aug. 3 – 60 mph
TS Erin – Aug. 15-18 – 45 mph
TS Fernand – Aug. 25-26 – 60 mph
TS Gabrielle – Sep. 4-13 – 60 mph
TD Eight – Sep. 6-7 – 35 mph
H Humberto – Sep. 8-19 – 85 mph
H Ingrid – Sep. 12-16 – 85 mph
TS Jerry – Sep. 29-Oct. 3 – 50 mph

TS Lorenzo – Oct. 21-24 – 50 mph
TS Melissa – Nov. 18-21 – 65 mph
A November 25, 2013, National Oceanic and Atmospheric Administration (NOAA) news release on the 2013 tropical storm season noted the following:
“The 2013 Atlantic hurricane season…had the fewest number of hurricanes since 1982, thanks in large part to persistent, unfavorable atmospheric conditions over the Gulf of Mexico, Caribbean Sea, and tropical Atlantic Ocean. This year is expected to rank as the sixth-least-active Atlantic hurricane season since 1950, in terms of the collective strength and duration of named storms and hurricanes. …
“Although the number of named storms was above the average of 12, the numbers of hurricanes and major hurricanes were well below their averages of six and three, respectively. …
“Tropical storm Andrea, the first of the season, was the only named storm to make landfall in the United States this year. Andrea brought tornadoes, heavy rain, and minor flooding to portions of Florida, eastern Georgia and eastern South Carolina, causing one fatality.
“The 2013 hurricane season was only the third below-normal season in the last 19 years, since 1995, when the current high-activity era for Atlantic hurricanes began. …
“Unlike the U.S., which was largely spared this year, Mexico was battered by eight storms, including three from the Atlantic basin and five from the eastern North Pacific. Of these eight land-falling systems, five struck as tropical storms and three as hurricanes.”
When completed, reports on individual 2013 storms (including tracks) will be available online at http://www.nhc.noaa.gov/2013atlan.shtml. Below is a preliminary map of tracks, as of 12/3/13.
