Radar observations from the San Juan WSR-88D and wind data from an
Air Force Reserve Unit Hurricane Hunter aircraft indicate that
Maria has just about completed an eyewall replacement. Based on
the now-dominant outer eyewall, the eye diameter has increased from
10 n mi to 30 n mi. This has likely contributed to some weakening,
and based on the latest observations from the Hurricane Hunters, the
intensity is set at 135 kt which is at the top of category 4 range.
Looks like my call wasn't totally off-base after all,...just somewhat aggressive with the weakening.
