UPDATE: As of the 11pm update from NHC: AS DANIEL APPROACHES THE HAWAIIAN ISLANDS...SSTS WILL BEGIN TO INCREASE AGAIN. CONSEQUENTLY...DANIEL COULD STILL BE A SIGNIFICANT TROPICAL CYCLONE IN FIVE DAYS.
Daniel continues to have a well defined eye but convection has started to weaken. A quick look at satellite imagery shows no signs of wind shear and a category 2 hurricane that is still well organized.
The hurricane is gradually moving over cool water, but since wind shear is weak and the water is expected to remain borderline warm enough to support a hurricane, rapid weakening is not expected at least for 3 days. NHC's official forecast calls for Daniel to be a tropical storm with sustained winds over 55 mph when it is near Hawaii. This forecast track is well inline with the bulk of the operational models which call for Daniel to pass over or near Hawaii is 5 days.
