OK so the SW to NE supplemental recon info tallies with the lopsided appearance of the convection on sat image. Well I am thinking if they find a stronger wind in the NW quad, then update to hurricane status, as pressure is dropping and temp diff is still very strong (7 deg). But that is not at all a sure thing, looking at radar. If not...the core will tighten up in a couple hours and then the winds should increase a little, enough to bring it to hurricane status.

So is shear the main factor? I saw shear on the outflow all yesterday aft but outflow still seemed to continue and to be going strong at the time, much better actually than this morning...does shear affect the stabilization of the core?
