How Unusual is a Named Storm This Late in a Hurricane Season?

November Atlantic Basin pleasant cyclones aren’t all that unusual.

In November, pleasant cyclones typically form where a waters are warmest. Thus, one cluster of storms combining in Nov is in a western Caribbean Sea.

A second extended area of arrangement is in a extended swath of a western and executive Atlantic Ocean, infrequently spinning off from an aged frontal boundary, infrequently transitioning from a cold-core low to a subtropical or pleasant cyclone.

According to NOAA’s best lane database, only 18 storms of during slightest pleasant charge strength had shaped on or after Nov 21 dating to 1950.

The final to do so was Tropical Storm Olga in Dec 2007. In fact, it’s now been over 10 months between a season’s initial named storm, a aforementioned Alex, and Otto.

If Otto becomes a hurricane, that would be even some-more singular on a integrate of fronts.

Only 9 pleasant cyclones became hurricanes in a Atlantic Basin after Nov 21 from 1950 by 2015. The final to do so was Epsilon in Dec 2005. 

Only one of those 9 hurricanes occurred in a southwest Caribbean Sea, Hurricane Martha in 1969.

Furthermore, in NOAA’s whole best lane database dating to 1842, there have been usually 3 Nov or after Nicaragua whirly landfalls, nothing of that were anywhere nearby as late as Otto could be.

  • Hurricane Ida: Nov 5, 2009
  • Unnamed Hurricane: Nov 1, 1890 (best lane has 00 UTC landfall)
  • Unnamed Hurricane: Nov 4, 1887

It usually gets some-more weird if a Costa Rica landfall occurs.

NOAA has usually one pleasant charge landfall, in any month, possibly from a eastern Pacific or Caribbean Sea side in their 174-year database, a Dec 1887 pleasant storm.

There is no record of a landfalling whirly in Costa Rica, according to a NOAA best marks database. Otto could be a chronological first, there.

More Nov Perspective

According to NOAA’s best lane database, there have been 36 Atlantic pleasant cyclones of during slightest pleasant charge strength in Nov from 1950 by 2015. Twenty of those became hurricanes. 

Just 8 years ago, Hurricane Paloma reached Category-4 intensity, a second-strongest Nov whirly of record, deleterious or destroying scarcely each building on Cayman Brac, according to the National Hurricane Center’s final report. “Paloma” was late from a Atlantic whirly name list following this event.

In a duration of record from 1851 to 2014, no pleasant charge or whirly has impacted a western Gulf Coast from Texas to Mississippi.

Systems that do rise opposite a Caribbean Sea can benefit some organization, as a area has upheld such late-season hurricanes as Kate in 1985 and Michelle in 2001. The former became a latest landfalling whirly in Florida’s story on Nov. 21.

Since 1851, Florida has been impacted by 8 pleasant storms and hurricanes in November. The usually other states with some-more than one Nov impact were also in a Southeast: Alabama, Georgia and North Carolina.

Typically, Nov pleasant systems follow upper-level upsurge and cold fronts northeastward into a Atlantic Ocean. 

In 2015, Hurricane Kate was an early-November oddity, combining from a tropical wave that initial dripping a Lesser Antilles, afterwards apropos a farthest north whirly so late in a deteriorate on record north of Bermuda. 

By a way, Atlantic Basin pleasant storms even form in December, and January, on singular occasions.
