The storm got under the label 'tropical' (then ex-tropical) only because it strayed into what is considered the 'tropical' to NHC / NOAA. I think they had little option but to give it a name.
My clients were some 120 miles off the center just before the storm got its letter. It was a typical 'off the front' system secondary that grew in the W and would otherwise go its normal route
towards the Azores. BUT the High retreated so much that the new low high dropped bomb-like all the way to lat 25 or thereabouts when it got to mid-Atlantic.
As someone already noted - this does bear some similarity to that 2015 system that dropped way below the regular track set for April / May storms, which ended in life and boats lost
in the group returning from the Caribbean
We can only hope these two events
are one(s) off. Sure, thing now that there have been two such events
, we are faced with a somewhat more demanding mental task. Esp. those of us who want to sail Carib to the Azores this year ...
