SHIPS are forecasting some slight strengtheing as do some other models, very interesting as the GFS goes into hyperdrive with development compared to its normal self, probably starts to get helped by outsid eprocesses past 72hrs IMO.
By the way the ECM drifts this is a little to the ESE between 96-120hrs then holds it near 60W/30N for 3 days.

Re:
yeah, that would be total madness for the forecasters. Having both Bertha and possibly Cristobal in the picture at the same time and in the same general area of the Atlantic would be a nightmare.KWT wrote:If the upper troughs can't do the job then eventually the upper high is going to try and rebuild again and either trap it or send it back west, it would be crazy if that happened!
Its made even more complicated if the wave off Africa develops as well.

Notice also, the curve towards the north, bringing the system (hopefully) just north of the islands. That one would be plenty far south to make it across the pond.

Re: Hurricane Bertha Model Runs
INTERESTING, I called a possible loop several days ago. Lets see if other models jump on board.

this is almost scary.. the nogaps does a loop and from the looks of it.. build the ridge in quitre strong over the western atlantic and the east coast .. which would move bertha west towards NC ... and there is no trough in site.

Remember Kyle? The storm stayed out over open water for several weeks, and
appeared to be headed for the North Atlantic at one point. It then
recurved, moved back to the SOUTH, and eventually affected the US coast.

Sorry I did. But was talking about Bertha making a loop and I thought I would post this here too. Sorry

Yep GFDL has Bertha undertaking a small loop though if the eye remains as large as it that loop probably just look like a wobble!
Will be interesting to see if the loops does happen, Bertha has tried its hand at nearly everything except being a cat-5 (I didn't say cat-4 becuase Sat.estimates may mean this being upgraded post season...) so it wouldn't surprise me if it does a loop!
