“Isaias made landfall as a strong Cat. 2 storm.. reach[ing] Cat. 3 intensity just prior… [the rule of thumb] is that [people] will not evacuate unless a hurricane is Cat. 3 or higher… With rapid intensification… you could go to bed expecting a Cat 1 or 2 storm & wake up to a Cat 3 or 4 at landfall.”
