Absolutely wild watching power flashes mixed with eyewall lightning as the core approaches.

Seeing power flashes occasionally on https://webcamsdemexico.com/webcam/acapulco-panoramica/ Dreams resort still up: Bahía de Acapulco en vivo, Acapulco - Webcams de México (webcamsdemexico.com)

Yeah, getting knocked offline one by one here. Dreams resort still going strong.

Notable increase in noise on the first resort webcam in the last 10m.

Needs to plow due N to spare the worst damage at this point. Last second left turn (aka NHC track) would actually be a huge negative.

Tonga paper had a pretty sizable regional ++ ridging tendency in this area in model years 2-7. Might be a player here.

Still time for recovery, yes. Just not a great start. Pattern gets better in the last 7-10 days of the month, but not looking like an upper 50% type of year right now.

Lmfao. Crushed it. Ended at 0.17 above this. Legit shot of not only smashing Feb. 16 but also printing the first 1.5C in the GISS data set.

Of course there's gonna be a competition and emotions. Snow is on the line here. More valuable than cocaine on this board. Has been for 20+ years (here+eastern).

The jump since '20 has been surprisingly strong. 60-65ZJ just since then.

Plenty warm enough given its location, strength and mode of formation. Not really a factor here. Don't forget that current speeds in the Gulf Stream are on the order of 1 m/s. Only takes a few days in that area to recover from upwelling induced by wind as there's always a fresh supply advected in.

Nino tends to suppress more over the Caribbean and GOM than it does out in the MDR or particularly the subtropical Atlantic. It's just that there's been a big expansion of the 26C isotherm both spatially and at depth over the last 40y (and especially the last few years) in these areas where a Nino won't really help stop development. Obviously if you don't have a mod-strong Nino in place helping shear part of the basin, then this leaves open more area over time to higher SSTs and OHC. ENSO isn't the only game in town though, and changes to static stability via SAL intrusions and the West African Monsoon are important too.

Doh! Poe's Law strikes again!

So, if you were to hand-draw a CONUS surface temperature chart with isotherms, you're telling me that the temperature would go *up* the more stations I have? News to me.

Gonna be wild if we end up breaking Feb '16 with a *September* reading, considering the current Sep. record is about 0.30 below that level.

Sep. already stacking some nuclear daily prints on moyhu. Prob going to end up above Aug at this point. Still 5 or 6 months of prints until ENSO peak.

Some pretty clear SW shear undercutting the outflow this AM on visible sat. Vortex centered skew-Ts show this persisting around the 300mb level for a good 36 hours, so this will likely limit strength until it abates.

Inversion down below 850mb now. Warm core getting very intense.

We'll have to see the dropsonde, but in especially intense TCs with very strong warm cores, the max wind can be under 10kft and have a smaller-than-normal reduction to the surface. (see: Mitch)

He probably just means significantly above the 135 kt threshhold. I mean, if Lee were to reach MPI after the first EWRC, it could get down in the 910s. A 150 kt storm is not impossible with this setup. I'm not calling for that as there can always be unexpected variables, but he probably thinks it will. Yeah, I mean the more reliable guidance is down in the 910s-920s with a superb setup and gargantuan upper level outflow channels, so it checks out. ERCs and a touch of mid-level shear are the biggest "issues".

Ah, the dreaded shrimp. This storm is speedrunning all of the harbingers of a future buzzsaw. Don't love that upstream pattern amplification trend on the latest runs, either.
