Very impressed with this as compared to just 12 hours ago, when I went to bed it didn't look like something about to go ham but this morning it's definitely on the road to earning a name. This year has surprised me with just how rapidly a fairly broad wave axis can become a very doom-looking tropical depression.

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Recent satellite trends are very concerning. Once an inner core forms.... Look out.

The HWRF has adjusted its forecast now that an exact LLC is present. It shows a slight southward dip before heading north and missing CA. Same goes for the HMON. The HWRF is showing a tightly compact core developing within the next 24 hours, so we’re gonna have to watch out for the start of a RI phase.

The best case scenario for Iota is an HWRF/HMON/GFS(ish) track: just enough north that it misses hitting Nicaragua and Honduras, where perhaps it could stall or get moved away by a trough or front. Some areas are still going to get hit hard by Iota, but at least with that track, it’ll spare Nicaragua and Honduras from another Cat 4 flooding disaster.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

A SW cross-over is against climatology so this should be interesting...

If it falls closer to climo it could be a Belize burner...

I think climatology is quietly sobbing in a corner right now whispering "just please stop..." so at this point I wouldn't be surprised by much lol

HWRF seems to completely stall Iota at the end of the run. Steering just..collapses...

And just like Eta, Iota’s life as a TD was brief.

TS, does that mean we have Iota at the next advisory? If so, then it's pretty much spot on with what HWRF shows right now. Actually the storm is even a bit further north than HWRF has it right now, since HWRF has it at 13.3N, even though it does move to 13.9N at 21z.

Hoping and praying recon will be more successful with Iota than it was for Eta. Hope they got all those mechanical issues figured out...

There is one expected Tomorrow

(In 2017, there was Recon heading into Irma from the Leeward Islands, will there be a similar one for 31L?)

Iota could ramp up really quickly even earlier than HWRF’s prediction.

The HWRF and HMON were two of the worst models with Eta, below the terribly-performing UKMET and always bad NGX.

No, there isn't recon currently stationed in the islands.
