Isabel was an unwinding former high end cat 4 or maybe a 5, lots more kinetic energy built up than Ophelia will have. Also, its forward speed started to really book at landfall, which I think led to a short period (8hrs) of strong winds. Rain wasn’t an issue in the metro really, but there was terrible surge in the bay and up the Potomac. Annapolis and Alexandria were hit hard. The area of Belle haven and Huntington south of old town were were both severely flooded by surge. All the bridges on the mount vernon trail were damaged or destroyed (in fact they are replacing them this year), so the seem to last 20 years. I Iived in the fort hunt area then and now, we were without power for 5 days during Isabelle. I don’t think Ophelia will be anywhere as impactful.
