I’m shocked that raw Ts haven’t started spiking yet. A +19 C eye and a nearly full W ring are present, what more does ADT want?

Because it's analyzing it like this:

That's close enough to whether it would accurately measure it's CDO and eye (hence the eye pattern). What's more notwhorthy about that is that Douglas is a little north than forecast.

The CDO isn't very thick at all. That's what's holding ADT back. Even LG is somewhat shallow.

Based off some of the data I have gathered over the last year, I'm calculating Douglas to have flight level winds around 144 knots assuming they fly at standard level.

That’s no less than 130 kt. A Category 5 seems likely.

:uarrow: Beast. Can't stop looking at it lol.

Stronger it is now, the stronger it will be on approach. Let's hope the ridge ends up being weaker and this finds a way to avoid hitting Hawaii as its ancestors did before it.

Looks like a WPAC super typhoon. Amazing banding features.

I’m wonder if the ridge will be just weak enough to allow Douglas to slip north of the islands? It’s going to be close either way though.

This is a system where if Recon goes in, they would find borderline Cat.5.

Even the more northern members of the 12z-18z guidance barely cleared Hawaii and that was the UKMET.

If an EWRC doesn’t try to start within the next few hours, diurnal max could help thicker that W ring. I really hope this is enough for the NHC to give it a well deserved 120-130 kt.

Stadium effect clearly visible from that image.

Max cat 4 to decent Cat 5 IMO from that gif.

Actually CDO thickening. Might qualify for T6.5 now but I'd need to measure.

I feel fairly confident if this had recon they would be finding a cat 5 right now. 140-145kts. Douglas is a picture perfect beast.

Second eyewall has formed, so an EWRC is imminent. Just needs to hold off a little longer so Douglas can get upgraded.

The fact that the East Pacific pulled a complete 180 in a week is impressive! :eek:
