The previous vortex from this mission had no eye description. Going back to the last
vortex from the last mission, which was at 10:51am Saturday morning, the eye was
closed and circular with a diameter of 20 nautical miles. Now it is over twice the
diameter, 48 nautical miles, still circular, and open in the SW.

947mb with 25 knots of surface wind, so the pressure might be about 944 or 945mb.
