Jose is still a viable storm with all the threats I have previously discussed.

That drop in central pressure at 09/20/00 occurred with Irma at one point. The wind speed didn't match the central pressure.
Below is the development of a mid-latitude vortex that at one point appeared to be a dual vortex. I think that was about 3 hours or so ago. It is the size of the USA and Canada.
These images are 11 hours apart. The hemisphere satellite picture is below.This is a first occurrence of such a phenomena.

The vortex stated here provides concern for severe storms in Canada and the USA midwest and plain states. It is finding enough water vapor to cause concern. By concern there is the potential for tornadoes.
