Feels so weird seeing that eye so close to us, I feel like a full on tropical cyclone hitting the British Isles must be possible at this point. (excluding Debbie and faith as there's uncertainty to their tropical status)

Are we nearing the point where we drop the line that hurricanes cannot reach the British Isles? That's two this year not far off, and even in silly cold waters. Something's changing. For sure, it must be a matter of years before Spain / Portugal get hit by a genuine cat 1 or 2 hurricane on the west coast.

This is what I was thinking. Surely at some point the conditions will have changed enough that Hurricanes will be a thing here.

Much to ponder in our global weather at present. Anyone with knowledge of hurricane formation got information on how a hurricane can be sustained over such relatively cool SSTs in the atlantic?

No longer a hurricane but what a strange brief episode

RIP Pablo. Blink and you missed it. Hung in well and strenghened briefly against the odds helped by cold air aloft.

Very rare beast and the idea of extremely cold upper air nullifying to some extent the sea temperature required is a new concept to me.  This will very probably mean some changes to data input at the main forecast centres.

Ultimately they are a function of high enough lapse rates to allow convection to drive the whole process. The combo of higher than average SST's and some very cold (relative) air aloft helps to really sharpen the lapse rates to the point where you'll get decent convection development and therefore drops the need for the temperatures at the surface to be as high as normal.

Its a similar process to what we get in the med at times with these hybrid storms, very cold air aloft with what would appear too cold SSTs on the face of it, but lapse rates still high enough for decent convection.
