ATL: CRISTOBAL - Post-Tropical - Discussion

[Hammy]

Certainly looks better than earlier, and there is also a hint of upper cloud movement towards the north at the end of the loop.

[TheEuropean]

pressure down to 988 mb, system may be reforming and intensifying now.

Looks like Cristobal reformed further south near 24.5N based on where they just found the lowest pressure.

Edit: The reported pressure of 984mb near 24.5 was an error, the LLC is near 25N.

[NDG]

Flight level winds of 73 knots, he's getting close to hurricane strength. Interesting that the vortex's coordinates is further north than where the recon plane was when they reported the lowest pressure, he most still be big time tilted.

how that affect track if their move center to south ?

[Sanibel]

Cristobal has enhanced a steady NE wind here. I think 990 73KT flight level IS a hurricane, isn't it?

Not quite there yet, recon is flying fairly high so those winds would equate probably around 65-70 mph at the surface.

I just edited my post, LLC is still near 25N, he has no other way but to go NNE to NE over time as the Atlantic ridge pushes in from the east-southeast.

He's now a hurricane folks!

Three for three so far this year.

[wxman57]

It doesn't matter where the center is, it's heading out to sea to the NE. Can't move west to the U.S.

Yes but that was in some serious high rain rates, they might be going more with flight level winds. All in all he's looking better tonight so I guess it was the right choice to upgrade it.

Three for three so far this year.

Even thou the expectations were for a lazy season it has been very interesting so far. Maybe the El Nino delay has turned the Atlantic a little bit more condusive.

[CrazyC83]

Bermuda needs to be watching closely though?

[galaxy401]

The Atlantic is certainly sprouting weird storms to track. Still it's 3 for 3 so far, can't deny that.

And notice were all three have become hurricanes, in an area that many included myself have been saying for the last couple of months that was going to be the area to watch because of persistent favorable conditions most times.

[galaxy401]

Where is the special advisory? I see "Hurricane" Cristobal on the NHC but can't find the special advisory.
