Those are wind shear tendencies over the last 24 hours, not actual wind shear values real time, which is currently much higher.

Katrinas outflow caused the wind shear in the NW caribbean and SE coast of the US.

overall, the shear right now in the Atlantic is less than when Katrina was in the Gulf.

What you are looking at is a mid level wind shear chart, the upper level chart shows higher wind shear.

Toggle between mid and upper level in the link below.

the shear tendency map is not based on mid-level shear. It is something completely different.

You can see the difference in the two maps, by comparing them below:

Shear tendency: http://cimss.ssec.wisc.edu/tropic/real- ... g8sht.html

Mid-level shear: http://cimss.ssec.wisc.edu/tropic/real- ... idshr.html
