Wider weather episode

An extended duration local nor'easter wind event developed October 9th and persisted through the 12th between high pressure wedging down the SE US coast and a sharpening coastal trough axis over the local coastal waters. 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. This inundation flooded roads and surrounded some vulnerable homes with flood water around high tides. Waves of showers moved onshore with localized flooding rainfall.
