RECAP "Hurricane Dorian: A True Tropical Beast"

**No areas of concern across the Atlantic that would affect the U.S. or any other land areas **

A fairly active tropical wave has emerged off the coast of Africa over the Eastern Atlantic.  No development expected as the wave will first encounter strong shear then will be steered to the north then northeast thanks to a strong upper level trough.

Overall... the pattern over the Atlantic Basin looks a lot like late fall.  Frequent cold fronts will push farther & farther south & east during the next one to two weeks thanks to a rather persistent & further south development of a series of upper level troughs.  Low pressure will occasionally develop along the fronts over the Atlantic but no indication - at this time - of any tropical development.

Nov. is the last "official" month of the Atlantic hurricane season.  Tropical cyclone origins - since 1851 - favor the very warm Western Caribbean & the Central Atlantic.  Only two hurricanes have ever made a U.S. landfall in Nov. - both in Florida: "Yankee" on Nov. 4, 1935 - at Miami..... & "Kate" in the Panhandle on Nov. 22, 1985.

Other notable storms include "loopy" Gordon in 1994... Lenny in 1999... Paloma in 2008 & Ida in 2009.
