Tropical Storm Zeta: October 27, Update A

Let's just start with our storm in the Gulf today shall we? Tropical Storm Zeta did weaken as it crossed the Yucatan and has remained like that as it carried on into the Gulf - so it's still a Tropical Storm instead of a hurricane.

It's currently at 23.8N, 91.2W, heading NW at 15mph and should be making landfall tomorrow in the Mississippi delta region. 


Officially the winds are 70mph, central pressure is 990mb, which makes it a very strong Tropical Storm (TS range: 39-73mph). I think it is a fully fledged hurricane at the moment, with winds somewhere closer to 90-95 mph actually, because there is good circulation in all levels of the troposphere and there is an eye developing.  The circulation remained strong throughout the troposphere as it crossed the Yucatan so I think it was a hurricane all the way through, although it's convection decreased as it wasn't over water. You can see the convection has picked back up now it's over water so the eye is getting a little more obvious:

I would call this a mid-to-strong cat 1 storm at the moment. As I said yesterday, the Gulf is cooler that is was a few weeks ago so that will keep it in check. Alas, the wind shear in the northern Gulf is no longer there so that won't be a factor anymore which means it has a little more room to develop before landfall. Although the official forecast calls for a mid-size cat 1 storm at landfall (around 85mph winds), there is a chance it could be a strong cat 1/weak cat 2.

Be safe out there my friends! You know the drill. More tomorrow. 

Meanwhile, I heard that the swells are going to be increasing in SW England tomorrow (thanks Victor A.!) as a consequence of the Remains of a Hurricane... that'll be Hurricane Epsilon if that's the case as it was last seen heading towards the Norwegian Sea part of the world. I suppose it's just stopping by for a nice cup of tea. ;-) 

Toodles!

p.s. sorry about the Rays not winning the World Series. I didn't even need to watch the game... I  knew the moment that happened when the fireworks went off like it was July 4th here in L.A.! Congratulations to the Dodgers - first time since 1988!
