King Tides and Rainfall Increase Chances of Localized Flooding in Volusia County

Posted On: October 5, 2025

UPDATE- 4:30 p.m. Friday, Oct. 10:

Another round of rain is expected to begin this evening, with 1 to 2 additional inches possible overnight through early Saturday morning. The National Weather Service extended the Coastal Flood Warning through the overnight hours and advises that the greatest impacts will remain east of I-95, where the ground is already saturated and water levels remain elevated. Additionally, high tides remain a factor, with the next cycle expected around 11:30 p.m., which may limit drainage capacity and increase the potential for compound flooding in low-lying coastal areas. Residents and visitors are urged to avoid driving through standing water and to stay alert for changing conditions. Stay informed by following the County’s social media channels, its Emergency Management app, and the National Weather Service as conditions evolve.

UPDATE- 11:30 a.m. Friday, Oct. 10:

A stalled weather pattern, saturated ground, and king tides are aligning to increase the potential for compound flooding in Volusia County’s coastal areas today. The National Weather Service expects an additional 2 to 4 inches of rain east of I-95 through at least tomorrow morning. With king tides expected around noon today, drainage capacity will be significantly reduced, increasing the risk of flooding in low-lying coastal areas. Residents and visitors are urged to use caution and avoid driving through standing water, which has already occurred on portions of roadways. Stay alert for updates by following the County’s social media channels, its Emergency Management app, and the National Weather Service as conditions evolve.

INITIAL POST:

Incoming king tides combined with continual rain may cause flooding in portions of Volusia County starting Monday. The highest tides are also projected to raise the risk of compound flooding, a situation that occurs when high tides, rainfall, and other conditions combine to push water to higher elevations than any one of them would on their own. When king tides raise the ocean, they can also reduce or stop the flow of stormwater drainage, leaving high-risk areas vulnerable to localized flooding. Because some drainage systems in the eastern portion of the county connect to tidal waterways, these effects can extend inland, forcing rainwater to temporarily remain on roads and in yards because it cannot drain as intended. As tides recede, the water will gradually flow out, and conditions will improve. Upcoming king tide dates and times for Volusia County include:

• Monday - 7 a.m.
• Tuesday - 8 a.m.
• Wednesday - 9 a.m.
• Thursday - 10 a.m.
• Friday - 10:30 a.m.
• Saturday - 11:30 a.m.

Households in low-lying coastal areas near streams and canals are encouraged to take precautions and remain alert through the coming days. To stay safe, residents should avoid driving through standing water.  While rain chances are expected to taper off midweek, tides will remain elevated through Saturday, Oct. 11, and minor flooding may persist in coastal and low-lying areas during periods of rainfall.
