What the 'Hurricane Season' sites miss is that coastal waterfront areas have destructive winter storms -Easterlies- that can be pretty bad collectively. This past winter was the worst I can remember. We had 2 storms per week for about 8 weeks, generally lasting 2-3 days. The river has visibly risen 3-4 inches this winter. It was tough to watch.
