Wider weather episode

Tropical Storm Eta offshore of the SW FL Gulf Coast tracked NE through the day, crossing NE FL while gradually weakening through the day. Strong, gusty winds and locally heavy rainfall impacted NE FL as bands of heavy showers moved onshore. The storm moved offshore of the NE FL coast in the afternoon, with improving local conditions over night. Elevated tides combined with persistent, strong onshore flow caused isolated minor flooding within the St. Johns River basin during times of high tide. Water levels were generally near or just below 1.5 feet MHHW datum at high tides.
