EPAC: OTTO - Remnants

[CrazyC83]

Notice the lowest SFMR was 41 kt, so most likely the plane never hit the true center (tough when it is 4 nautical miles and very dynamic).

[1900hurricane]

00Z working best track is up to 75 kt.

[northjaxpro]

Yeah, Otto has looked impressive on satellite imagery for the past 6-8 hours. Probably will see the eye pop out very soon. Rapidly intensifying cyclone. Recon will find winds at least approaching in the 95 kt range or higher later tonight or early Thursday imo. A very impressive tropical cyclone and my prayers to all in the Costa Rica region as Otto makes landfall within the next 24 hours.

I'd expect this to weaken to 70-75 kts just given how small this is. I'd be surprised if this can sustain itself at this size

[Alyono]

maybe NHC is handling this a bit better than I first thought. Had they went with the very high wind speed and then indicated weakening, perhaps some would have felt that the threat was decreasing. However, best track needs to sort this out.

Almsot like a quick eyewall replacement occurred as the eye diameter is up to 7 NM

[NotoSans]

Looks really unstable right now - pressure up to 981 mb per the latest recon pass.

It may have weakened a bit with pressure now up just a bit, but there may be just enouugh time possibly for it to recover later to intensify just before landfall. Whether it is enough time for the cyclone to intensify to high end Cat 2 or low end 3? May or Maybe not? Still an impressive cyclone nevertheless!!

[HurricaneBelle]

the overshooting cloud top seems to be decreasing in intensity. This may weaken somewhat. Given how small it is with a 4 NM wide eye, this is not exactly a very stable system

So you're saying continued strengthening is not going to be Otto-matic?

(I'll show myself out.)

[Yellow Evan]

Solid CDO, though recon suggests its inner core is not as well organized as I would like.

[CrazyC83]

NHC went with 75 kt although with a great deal of uncertainty.

[bg1]

I was looking at the latest Rainbow loop, and wow! White patches? Black pixels WITHIN the patches?

[weathaguyry]

I really think that Otto has been a truly astonishing storm, I was surprised when he reached Hurricane strength the first time, but then he weakened and I was thinking that he had less than a 10% chance of hitting Hurricane strength again, and that if he did it would be in the last advisory before landfall at 65kts. but Otto has really overachieved and has become a 75kt respectable category 1 Hurricane. Who knows what he's capable of now? (I remember on the model runs thread, people were laughing at the idea of a thanksgiving hurricane)

[BZSTORM]

can someone point me at reasonably reliable model forecast that will give best indication for precipitation - I am hearing Southern Belize could be impacted with heavy rain in next day or 2 and looking at the tail Otto is dragging behind that seems likely. Thanks in advance still learning how to read model data so any input welcome

[HurricaneRyan]

Otto, along with Nicole and Matthew, really are the trinity of storms this season in terms of surprises.

[TheAustinMan]

Sizeable hot tower showing up quite noticeable on rainbow-IR enhancement. Often a portent for strengthening, but Otto doesn't have too much time left over water, luckily.

[Digital-TC-Chaser]

latest shortwave i could find,expanding cdo looking looking more symmetrical. On vapour sat the system also looks like there is now a, development of both a poleward and equator outflow channel

[Vince_and_Grace_fan]

The HWRF now show re-intensification in the EPAC to a strong Category 1 hurricane (around 980 hPa central pressure and 80 kt wind). Probably this would be the first occurence that the EPAC get a hurricane both from ATL and CPAC in one season.
