Philippe's track makes a big difference. You can see it in the models, which go back and forth between a major hurricane and a struggling tropical storm. Philippe's projected track brushes the west end of a piece of subtropical jet. If he goes a little west he gets mild shear and becomes a major hurricane. If he goes a little east the jet blows his head off and he might even dissipate. He's under westerly shear now and you can see the convection is east of the LLC. http://www.ssd.noaa.gov/PS/TROP/DATA/RT ... loop.html The active area just to his north is the jet, with up to 60 knot (!) westerly shear.

Phillippe appears to be strengthening this afternoon. An impressive central dense overcast has explosively developed over the center of circulation suggesting that the storm is stronger than currently estimated by the models (6065mph). The system will likely become a hurricane during the day tomorrow. There is some rather strong westerly winds north of the system, but the models forecast the anticyclone to move in tandem with it and keeping in a light shear environment.
Phillippe has been a well behaved storm. The storm has followed the pattern and guidance which had the system moving just to the east of the Lesser Antilles. It should continue moving NW during the next few days due to the unusual weakness in that part of the Atlantic. The track reminds me of Iris in 1995, which abruptly turned northward when it was over the islands.

At 5pm, Phillippe has been kept as a 50 mph tropical storm. This is likely due to the Dvorak intensity estimates, which are 3 hours old, indicating such. However, as I pointed out in the previous post, the system has definitely become better organized over the past few hours and that should be reflected tonight.

Probably will become 17/9/6, as both Philippe and Rita go for major. Models tonight don't show Philippe as a major, but I still think it will make a run for it at least.

At around the same latitude as Rita since it is the same ridge. Most of the models are showing a weakness forming before any significant westward motion happens. A few do not show the weakness like the CMC.

But this does not stop here because there is 97 on the horizon.
