18z HWRF has Hurricane Eta in 24 hours and a compact Cat 2/3 in 42 hours. It’s been very consistent with a tight circulation; recon will confirm whether it’s right or not.

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.

The "foe" function would work a lot better if people didn't keep quoting the "foes", just saying.

18Z HMON brings it onshore at 5:00 PM compared to around 11:00 AM on the 12Z.

18Z HWRF about 9mb deeper compared to 12Z through 48hrs.

Does the NHC even take this into consideration?

18z GFS in the mid range was a slow cave to a bury into CA. I expect 00z to continue the SW adjustment into a full CA landfall.

The experts have low confidence in any of the models beyond 3 days and are awaiting future runs.
After a storm weakens and unwinds over land sometimes they redevelop like Mitch did in 1998 but that is in the long range fantasyland beyond any kind of certainty. Probably reemerge off Belize rather than the Bay of Campeche if it happened at all though.

It's not -removed- when there's actual evidence and support towards a solution. The GFS, GEFS, and CMC all support some kind of northward or northwest movement after the southern dive within the next 4-5 days, which isn't fantasy land. It's a legit scenario and depends on the strength of the system and timing of that shortwave trough over Louisiana. If it's earlier and or stronger it could very well prevent a CA landfall. The same goes for a stronger 29 and possibly feeling that weakness. What happens after that has many different ranges, but it's nonsense to chalk up these GFS runs as -removed- when they synoptic setup very well could allow for something similar and when there's currently ensemble support.


I don’t want to get into any fights. But it’s -removed- when people take 1 run run out of 100 that’s more than 7 days out and start drawing attention to Florida and how it’s time to panic. Like seriously. Relax. Let’s just focus on the next 3-4 days. That’s all I’m saying.


It hasn't been one run though, it's been 5 runs with GEFS support.


The CMC and GFS para both show similar solutions and the Euro shows some kind of weak system heading that way but staying east

What color is AEMI? I see the words but I can’t tell which piece of spaghetti it is.

Forecasts that keep the center over CA must concern those countries after the 1998 Mitch disaster. It's still early.

P.S. I'm guessing per tradition the NHC will not rely on "spaghettios" because of it's appearance - can you imagine their showing that mess to the public? IMO there's now too much information out there - similar to the days of a few tornado chasers to the past few years where there are so many they cause traffic problems. The NHC has always preferred a "smoothed" amount of data to make it as easy for the public to understand as possible.

Too much information is just as bad as not enough...
