Less than two weeks left in the 2017 hurricane season!.......

Weak low pressure continues over the far Southern Caribbean.  Close proximity to the landmass of S. America + some shear will likely inhibit much development.

Otherwise.... a succession of cold fronts are rolling east & south giving the Atlantic Basin a late fall look with widespread areas of strong shear.

Images below from the Storm Prediction Center showing tornadoes (preliminary counts) spawned by U.S. landfalling tropical cyclones.  The great majority were associated with "Harvey" - 57.  The 119 for the year ranks 4th since 1995 only behind 2008, 2005 & 2004.

Interesting map below tweeted by Erik Pindrock shows virtually all of Fl. has experienced at least tropical storm force winds this year... as well as the entire Gulf Coast... & as far north as N. Carolina on the east coast:

Interesting tweet & graph from Dr. Phil Klotzbach, CSU - "no statistically significantly trend":

Deep oceanic heat content continues to wane as we go deeper into fall.....
