Isaac's Chimney

Isaac, throughout his entire lifespan thus far, has not been vertically stacked. The 500mb has either been displaced S of the 850mb vort, or both the 850 and 700mb vorts. That is .. until now. Note the vertical stacking and the intensity of the vorticities (which have all tightened and strengthened over night).





Also, Isaac has lacked the strong LL convergence over the center... again.. until now. The UL Divergence is strong, but slightly displaced from the convergence center. This may change, but even if it doesn't, the divergence enhanced by the UL anticyclone is impressive.




Needless to say, all signs appear like a 'GO' for strengthening. OHC and SSTs are high and he has nearly a full day before he *might* interact w/ Haiti. Time to watch closely.
