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

A rather strong upper level low is producing heavy showers & storms over the Central Atlantic which may lead to the development of low pressure.  There's some chance for long term subtropical or even tropical development, but the system looks to stay far out to sea & well to the east of the U.S.

Overall... the pattern over the Atlantic Basin looks a lot like late fall.  A cold front is pushing into the Central Atlantic trailing back to the southwest & west across the Northern Bahamas & S. Fl. Frequent cold fronts will push farther & farther south & east during the next 7-10 days 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 in 1985.
