Do what??? I said a few days ago I thought this thing was gonna go into the panhandle if Florida. I stand by this.


Nobody knows what's gonna happen with this thing... and as for predictions, I'm comfortable betting against yours, until proven otherwise... nothing personal

Just so I don't come across as a complete troll to you since you obviously have a good bit of personal interest in NWP, I will try to clarify my stance on NWP a bit more eloquently than a carpet adjective such as useless. My predictability, usefulness, etc. comment was directed towards the highly stochastic nature of even early time evolution of a storm. Thus the dubious comment at studying models that are gross approximations and thousands of miles apart in a mere several days.


Ok, see you didn't say that in your fist statement. You made a blanket statement about NWP. I think everyone involved in the field that has an understanding of mathematics/statistics/modeling understands the limitations that models have when trying to resolve cyclogenesis. I think we are actually on the same page.

Can you recomend any books to get me started?


I posted links to a couple of books in another thread but the 2nd book no longer appears to be free:

Practical Meteorology: An Algebra-based Survey of Atmospheric Science

Tropical Meteorology appears to not be free anymore but if you can find the PDF online, this is a great follow on book.

Great loop, overshooting tops casting shadows are always awesome to watch.

Eric can rub people the wrong way at times but I'm glad he counted that up

The spread includes hurricanes from the Yucatan to east of Gaston...

So...if it follows the same north, then northeast turn, it will be coming in around Gulfport instead of Pensacola?

Looks like it's just a low pressure system, right? 1008 mb is barely even low pressure. Is intensity something these models struggle with even more than track?

It's starting to get close enough to see on actual radar, and the loop below shows some definite broad spinning around the area where the presumed LLC currently is. You can almost fill in the rest with your imagination and see it clearly, or at least I can. Still VERY incomplete evidence here, just thought this particular loop of the very outer edge of the storm looked interesting.

Ends up in about the same spot as a weak system.

It stays pretty weak on the GFS, maybe a minimal TS at landfall.

How "scientific" or accurate is the Earth Wind Map? It's showing an awesome view of the area of circulation, but not sure if that is even credible info.

Geaux,

I remember someone addressing this much earlier in the thread. I don't remember how far back or even what was sais]d exactly. But their explanation gave me the impression that the earth wind map is "somewhat" accurate. Maybe more accurate for large general areas but not as accurate as the scale gets smaller.

I could be completely off on my recollection however.

Hope that vague and back and forth answer helped you.






ETA: I recommend listening to the answer below me.

It is based off the GFS but I believe that Bay posted earlier in this thread that it also uses sone real time obs. So probably more accurate in areas with a higher number of obs.

It's based off the GFS model, so its not necessarily a current, accurate depiction.

The GFS brings "Ian" much more west this run obvious it will change over time

A storm that strong making it to the carribean... all bets are off. A storm that strength would make it's own path.

The African storm may be the real hermine
