SHEAR, that dreaded monster thats killing most of the tropical systems so far, with of course the notable exception being Alex, is affecting 92L now, sw to ne. Looking at the future shear maps, if it can remain south of 20 latitude or gets past 60 longitude, in 48 hours plus, it should be in a more favorable environment for development. Obviously if it goes more NW initially then it probably won't have a chance. Here's a link to the 48hr(Sun) shear forcast.
