Gusty winds of 40-51 mph impacted coastal areas, with the strongest winds from 10/9 in the afternoon through 10/10 in the evening along the Duval county coast of 51 mph. Tidal flooding reached moderate levels along the coast, Intracoastal Waterway and inland within the St. Johns River and its tributaries 10/10 through 10/12.
