Arlene continues to strengthen, Hurricane Warnings issued - 10:00 pm CDT
UPDATE: A new circulation center seems to be forming to the northeast of the old center. If there is another convection flare, things could get interesting again.
UPDATE: I think I am going to wait and see what happens here. It seems like every time we see a convection flare, the storm reorganizes itself slightly and strengthens a bit. Remember, in a tropical system, the true judge of strength in the central pressure (which has been dropping).
