Agree with you, NHC even has this verbiage in the 4AM discussion…. Isaias will likely become a major hurricane soon with the improving satellite imagery, and it could continue to intensify for the next 12 hours or so while it moves over very warm and deep water. However, a large increase in shear is anticipated before landfall, which will probably cause some weakening to occur. This is a tenuous spot because it would only take about a 6h delay in the onset of the shear to bring a stronger hurricane than expected onshore. .
