"Flooding is the most common natural disaster in the United States. With many low-lying areas, the St. Johns River, and other waterways, Duval County is always at risk for flooding regardless of whether a tropical cyclone is affecting our area. The impact of a tropical cyclone can vary depending on the amount of rainfall, wind intensity, high or low tide, storm surge, and wave characteristics. The St. Johns River flows north towards the Atlantic Ocean. As a storm approaches, water begins to back up the river, slowing down its flow into the Atlantic. When paired with high tides and rainfall, widespread flooding is a major threat.
