Notes~danielw: 11 degree F difference in the Eye temperature/ dewpoint. Storm center is working properly. Evacuating air through the Center.
EYE is open to the Southwest and is elliptical with a 20nm length and 16nm width. Orientation of the EYE during the fix was NW to SE.
Min Central Pressure of 989mb give a Max Possible Wind Speed of 86mph.
Rina is still under the pressure/ wind speed curve.
