Folks, that's 83 knots in the NE quad. Being generous and using 90% reduction from flight level (which only should be used for storms w/ heavy convection, which Jeanne currently does not have), yields 75 knots. 85% yields 70 knots. So the storm is an 80-85 mph storm, 85 mph AT BEST right now.
Regarding the pressure argument...remember, Frances had a pressure of 975 mb when she was a 65-mph tropical storm. It's all about the organization of the inner core, and currently Jeanne's is loose. That could all change, though.
