Melissa over Jamaica was similar. If Melissa had been a long-tracked Cabo Verde, it would have been much larger when striking Jamaica. Sure, it may not have been as intense since multiple ERCs would preclude its sub-900 mb intensity, but a large Cat 4 impacting the entire island vs. only 1/3 of the islands getting Cat 3+ winds is not the same. Also, the wrn 1/3 of Jamaica is significantly less populated, and one of its main airports went largely unscathed, and the other being on the N coast on the wrn side of the island had sig less impact than if it were on the S side. Compare to Gilbert at Cat 4 in Sep 1988 that cut down the full length of the Jamaica E-W w/ the entire land devastated. 80% of home lost their roofs. At least w/ Melissa on about 1/2 of the island, one could find relief, relatively speaking, short-term before full aid arrived and was distributed. 2 1 Link to comment Share on other sites More sharing options...

I have a feeling I know which one is going to win I am assuming that the AI models use historical tracks and climatology more so then the physics models. From my understanding of AI. Not your typical analogs but everything that’s possible. If anyone has more information on the subject I would love to hear it. . Link to comment Share on other sites More sharing options...

Yeah it's mostly machine learning data correlations and such as far as I've heard, but I'm not sure that the specifics are really well understood by the weather community anyway. Actually there was a little segment about the deep mind and Isiais on NPR this morning and they were saying how mostly the project is worked on by non-meteorologist, not even programers with meteorology experience, mostly neural network engineers 2 Link to comment Share on other sites More sharing options...

LongBeachSurfFreak Posted Tuesday at 09:47 AM Share Posted Tuesday at 09:47 AM Textbook truck tireJTWC has it at 135kt currently. I would say it should be 155kt. This has been one of the most underestimated TCs I have seen. . Link to comment Share on other sites More sharing options...
Windspeed Posted Tuesday at 11:30 AM Share Posted Tuesday at 11:30 AM Impressive large eye that continues to warm. Deep surrounding band of coldest CTs. If you'll notice the geometric pattern within the low-level clouds in the eye, most likely the result of multiple rotating mesovorticies currently riding around the eyewall. I'd imagine this is Cat 5 bound again. 1 Link to comment Share on other sites More sharing options...
olafminesaw Posted Tuesday at 11:47 AM Share Posted Tuesday at 11:47 AM Obviously Taiwan is used to heavy rainfall in the higher terrain on the East side of the island, but 20+40" of rainfall is going to cause some serious flooding I can only imagine.Also check out that rain shadow!

Champi just made landfall on Taiwan Yes, so this is a lesson about AI models. They are not infallible and can be off quite a bit. Just I see some putting them up on pedestal and worshiping as to having the final say. And look at what a physics-bases model (ECMWF ENS) did. It even caught the odd motion from terrain influences so common for when a TY approaches Tawain! 1 Link to comment Share on other sites More sharing options...

I find this a bit misleading in the larger pix. Of course a newer model is going to be pushed and pointed out more often -- b/c it is new! Makes for better news stories. Also, beware of cherry-picking. For any given fcst, you often can find a model (AI or otherwise) that did much better than the others. Par for the course. Just is it pointed out a lot in the MSM or not? It's like the ECMWF praise that was big after Sandy. Sure, it nailed far out a mega event, but the ECMWF overall skill perception was somewhat tainted by this very fact. It did not mean that the ECMWF was the GOAT and panacea for all out fcst woes going forward! I recall ppl using the ECMWF blindly for fcst solutions b/c it was the ECMWF! That's not good fcst science. One needs to see stats for all fcsts for the model, not just one that happens to get a lot of attention and had high sensible wx impact! That does not mean GDMI is useless or should not be praised, but let's not get carried away. Link to comment Share on other sites More sharing options...
