Re: GFS continues development off Africa 2 days and counting!
Trying to get into specifics such as whether it goes "out to sea" or makes landfall somewhere is just speculation. Forecast skill for tropical cyclone location 14 days in advance is very low-non existent at best.windstorm99 wrote:For the fish....

That's why it's been back and forth from the Yucatan, to Florida, to New York, to re-curving.

500 mb pattern from Hour 216 from 12Z GFS

500 mb pattern from Hour 228 from 00Z GFS

The east coast trough is much deeper on the 12Z run and slower. Notice that 594 dm ridge over the SE is gone in the 12Z run also. You just can't use these runs with any confidence at all at 9 days out.

Re: GFS continues development off Africa 2 days and counting!
The question is if the ridge is starting to build or retreat as this system gets close to the EC. The GFS goes from skirting the EC to out to sea, so there must be a trough setting up during that time frame. All about the timing.

Re: GFS continues development off Africa 2 days and counting!
I am very much doudting this northern track given the upper air variables in front of this system. Aric stated correctly, I do not think this system would develop so quickly and may meander in low intensity like 99 and 96l. We may very well be watching the unfolding to a Carribbean system with low lat tragectory.

It's really shooting in the dark when you look 300 hours out folks. Expect the GFS to flop back and forth between ridging/troughiness scenarios. In addition, it may end up dropping this system all together, you just don't know.
In fact we won't know more for about 1 week. Now is nearly impossible to project anything.

12Z CMC is bullish on Cape Verde development - track slightly northward of GFS. Waiting on 12Z UKMET.

12Z UKMET develops a weaker version and faster than GFS & CMC.

Has anyone seen what is going to come off the coast? I have seen better storm than that to roll off and died as soon as it hit the water. I think I would go with the UKMET with this.

Re:
Reminds me of 2000, when we had hurricane Alberto (Atlantic) and TS Beryl (GOM) at the same time. Right around this time of the month too.Extremeweatherguy wrote:If this forms and the possible system in the GOM forms, then we could easily be looking at 2 TCs at once next week. That would be interesting after such a quiet last few weeks.
