I doubt that the wind is gusting to 173mph in Kingston, considering that the city has remained well north of the eye wall. It appears that Portland Point on the southernmost peninsula of Jamaica came closest to the northern eye wall. Fortunately, the area is a designated protected area and there are no major population centers in this region.

This is about as bad as a hurricane can be in Jamaica without a direct hit. The island is on the worst side of the storm, with the wind and surge being enhanced by the fast forward movement. The storm surge must be incredible on the concave segments of coastline on Jamaica's south and southeast coasts.
