the world, the litany of climate change related extreme weather
events reached an extraordinary tempo over the past week. And it is
becoming difficult for even climate change deniers to ignore what is
increasingly obvious. The weather on planet Earth is getting worse.
And human-caused global warming is, in vast majority, to blame…

#Lee is now a major hurricane with max winds of 115 mph - the 7th Atlantic hurricane season on record with 5 Cat. 3+ hurricanes by Sep 27.

locally to the U.S., in the North Atlantic warmer than normal surface
waters have fueled the odd development
of hurricane Lee into a category 3 storm.
It’s not really that strange for a major hurricane to develop in
the Atlantic during September. It’s just that we’d tend to expect
a storm of this kind to hit such high intensity in the Gulf of
Mexico, or over the Gulf Stream, or in the Caribbean. Not at 30.6 N,
56.8 W in the Central North Atlantic south and east of Bermuda and
strengthening from a weaker storm that was torn apart in the
Inter-Tropical-Convergence-Zone, before drifting considerably to the
north over what would typically be a less favorable environment.
lasting for so long and hitting such high intensity produce a lot of
energy. And the primary measure we have for that expended energy is
ACE or Accumulated Cyclone Energy. 2017 is bound to achieve one of
the highest ACE measures for any Atlantic Hurricane Season. Since
1851, only 8 years have seen an ACE value hit above 200. Present 2017
ACE is at 194 and climbing. Highest ever ACE values were recorded in
2005, at 250, and 1933 at 259.
2017 continues to produce strong, long-lasting storms over a record
hot Atlantic, it is easily within striking distance of a record ACE
year. The restrengthening of Lee to major hurricane status so far
north and out in the Atlantic was yet one more surprise that shows
how much energy the Atlantic is bleeding off this year. Such a
tendency will likely continue through October but with storms
probably not forming quite so frequently as during September and
originating in regions closer to the Caribbean and U.S.
