Tropical Depression Ernesto - 35 mph - 1004 mb - W 14 mph

Lets see what happens over the next 12-18 hours. This was Karl's track while it was in the same location. If Ernesto can hold together as well as Karl did (unlikely) more intensification is possible in the Gulf of Mexico.

Karl (2010)

Ernesto (2012)

A lot of things had to come together just perfectly for Karl to re-intensify like that post-landfall. After all, Karl was the only recorded major in the BoC ever! I have a feeling the slightly larger circulation associated with Ernesto may make it more difficult to re-intensify as rapidly. But given the incredibly favorable UL pattern that has developed right over Ernesto plus very warm SSTs in the BoC, I wouldn't rule anything out!

Well the first step is that Ernesto needs to maintain its inner core. If that collapses, then I wouldn't expect anything more than modest intensification (like back to minimal hurricane intensity per the NHC forecast).

So far so good. The eye is still almost as pronounced as when it made landfall a few hours ago.

the IR has a much more defined eye now then during landfall. I think Ernesto will weaken to a 70 mph tropical storm before udergoing mild RI in the BOC up to a strong cat 2

Good news and bad news.

The good news, even as cloud tops warm, I can still identify (what I am pretty sure is) the eye on IR imagery. The Yucatan has not badly dsrupted the circulation.

The bad news, it has started to slip latitude, and if it doesn't stop, it will spend little time over open water in the BoC. I have the lat-long lines turned on on the floater loop. It hasn't slipped much in latitude, but it is slipping.

Good day,

The bad news, it has started to slip latitude, and if it doesn't stop, it will spend little time over open water in the BoC. I have the lat-long lines turned on on the floater loop. It hasn't slipped much in latitude, but it is slipping.

It has DEFINITELY lost lattitude (not gained it). It's a south of due west motion. I touched that subject while sending congrats to Josh M on the the "chase thread" for Ernesto.

For another landfall "rivaling 2010's Karl" ... It's appearing less likely as long as the WSW (or S by West) motion continues.

I think it was pretty clear what I meant by slipping latitude.

But it is at the point now, I'm not sure the center will ever completely re-emerge in the BoC, and it will have a difficult time becoming a hurricane again.

Looking less and less likely that Ernesto will pull a Karl. Ernesto will probably never get much if at all above 19N again, which gives the storm little time over water and keeps frictional convergence and land interaction in play for the southern rainbands (possibly even eyewall) even while the center is over water. So, unfortunately, the first landfall will very likely remain the strongest point in Ernesto's life.

Yep... there is still some question if Ernesto will ever emerge into the GOM. So far, not looking very promising based on the radar. With convection dominating the southern quadrant, the center will likely be pulled S of due west.

994mb extra with 41 knots winds. This little vortex has maintained across the Yucatan.

Convection is redeveloping over the center in a curved band that is rotating northward around Leguna de Terminos. The center has responded by drifting a little further north. Given the continued outstanding outflow and improving radar presentation, a return to hurricane intensity is certainly possible *if* it can stay over water.

Huh...

86 knot flight-level winds with 59 knot surface winds.

It just means the FL winds are not quite reaching the same % they normally due since the circulation is in the process of reconsolidating.

With that said, there is no doubt Ernesto is wasting no time re-intensifying. Lets see if it can gain some latitude.

Although it appears to be improving on Sat, the small core appears to have been absorbed into a larger core. Not enough room for a big storm this close to the coast so reintensification probably won't happen. The windspeed reduction reminds me of Irene. The flow of the outer radius is probably jammed by the mountains at the low levels.
