Fred weakening, and 80th anniversary of Labor Day Hurricane

Since my last update on Monday morning, Fred has weakened to a 45mph tropical storm and is quickly on the way to becoming a remnant low.  The Big 3 environmental factors for tropical cyclone intensity (sea surface temperature, wind shear, and low-level humidity) are all plunging into ranges that have caused Fred to quickly dissipate.  All that remains is a low-level swirl northwest of the Cape Verde Islands.  Although it was a short lifetime, it was the easternmost Cape Verde hurricane on record, which is certainly noteworthy.


Elsewhere across the Atlantic, there is nothing brewing in the foreseeable future.  This is a bit unusual as we ramp up to the climatological peak of the season!

Tonight is a very special anniversary... 80 years ago on the night of September 2, the most intense Atlantic landfalling hurricane on record hit the upper Florida Keys (Long Key): the infamous 1935 Labor Day Hurricane.  It made landfall with sustained winds of 185 mph and produced an 18-foot storm surge in the upper Keys.  It's worth pointing out that it was a tropical storm just 44 hours prior, so yes, tropical cyclones are capable of incredible intensification rates when conditions are ideal.  Even in 2015, I can say with confidence that we could not predict this super-rapid intensification.

If you use Facebook, my friend and hurricane historian Michael Laca has an excellent collection of photos and information from the storm: https://www.facebook.com/media/set/?set=a.220683491357229.52229.218869288205316&type=3&pnref=story

There's a beautiful memorial in Islamorada (which was completely obliterated that night) to commemorate the approximately 400 people who died in the storm... here is a photo taken by Michael.  The plaque at the base of the monument reads: "Dedicated to the memory of the civilians and war veterans whose lives were lost in the hurricane of September Second, 1935."
