Hurricane Florence and the Atlantic Blobette: September 5, Update A

A busy week this day ;-) so I'll be quick... 

Hurricane Florence
Well she not only went on the magic roundabout, but she's also had a go on the swings and slides since yesterday. She was, momentarily, a cat 4 storm, but she's now down to a strong cat 3 storm with winds of 125mph (cat 3 range: 111-129mph), central pressure 956mb. Florence is a good looking storm and has really good vorticity (circulation) in all levels of the troposphere, plus she has had a very clear eye and outflow during the day today:

 Although the wind shear did nothing to stop her from getting stronger earlier today, you'll notice from the satellite imagery that in the last couple of hours that she is really beginning to feel it and, in addition to the convection being mostly to the north and east of the eye, the eye itself is not as well developed. From this, I think she's probably now a weak cat 3 or strong cat 2 storm. 

She is still on track for the general Bermuda direction, but it's still too soon to say for sure if she'll visit for a round of golf or she'll do something else: 
She is currently at 23.4N, 47.2W, heading NW at 10mph. 

Atlantic Blobette
This one is somewhere around 12N, 30W, heading generally WNW. The circulation is slowly developing in the lower half of the troposphere, but isn't quite there yet. There's some convection in this system, so if the circulation continue to improve, this will be our TS Helene in a day or so. 

Finally... Happy 50th Wedding Anniversary to my Mum & Dad! :-) :-) 

That's it for now!
Ciao,
