Why aren't there any graphics with 'Fernanda' with the 5 A.M. PDT package on the NHC website?

they only update graphics at 2 & 8 am/pm , unless there is something pressing: http://www.nhc.noaa....cgraphics.shtml

"Graphics for Eastern Pacific tropical cyclones are normally issued every six hours at 2:00 AM PDT, 8:00 AM PDT, 2:00 PM PDT, and 8:00 PM PDT (or 1:00 AM PST, 7:00 AM PST, 1:00 PM PST, and 7:00 PM PST).

The graphics will also be updated when intermediate public advisories are issued, and special graphics may be issued at any time due to significant changes in warnings or in the cyclone."

I saw that mandarin off MX this evening, and I almost got excited-- but the models keep it moving parallel to the shore, and the SHIPS is not enthused Re: intensity.

Blah.

Looks nice. It is a little too close to land, though.

ETA: Board is funky- this posted 3 times. I deleted the other two...

The SHIPS does bring 93 to a strong tropical storm, stronger than a lot of the other guidance. The biggest problem will be 93's interaction with land as it will be difficult for an organized outflow pattern to develop. With that said, 93 does appear to be more organized this morning. I would be surprised if we don't see an upgrade to a tropical depression later today.

But it already looks like it has a pretty-good outflow pattern, doesn't it? Check out the fanning out from the center.

It's moving roughly parallel to the coast and it looks quite small, so I'd bet land won't hurt it a whole lot, actually.

Yeah as soon as I posted the visible, I was thinking the same thing. If it can stay fairly small and compact, it might actually have a chance.

Yep.

But, darn, it sure is close to the coast-- more so than I realized. And I agree with you, that may end up being the biggest inhibitor. I guess that's why the intensity models aren't terribly enthused. Too bad-- it's got a nice shape.

The EPAC has awakened again. The GFS and Euro develope a cyclone hugging the coast of Mexico over the next several days.

It finally looks like the EPAC will have another tropical cyclone... 96E looks like a slam dunk with very favorable conditions out ahead of it. Looks like a potential hurricane in the making with both the ECWMF and GFS suggesting robust development into at least a hurricane.

We're just about getting to the time of year when EPAC cyclones start recurving toward the coast. I don't have high hopes for this one, although I notice the NOGAPS does swing it N.
