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

A rather compact area of storminess/low pressure continues over the Central Atlantic hundreds of miles east of Puerto Rico.  Some gradual tropical or subtropical development is possible as the evolving low pressure system drifts to the northwest then north through midweek before merging with a frontal system & accelerating northeast late in the week.  Once merged with the cold front, transition to an extra-tropical low pressure system will occur over the open North Atlantic.  No impact on the U.S. & the system should stay south & east of Bermuda.

Less than two weeks are left in the Atlantic hurricane season!  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.
