Slow-moving St. Johns River flood keeps 14 Florida counties under state of emergency

Ten days after a stalled storm dropped nearly two feet of rain on parts of Florida's Space Coast, the water is still moving north through the St. Johns River, pushing the slow-rolling flood into Seminole, Volusia and Lake counties and keeping a state of emergency in place across 14 Florida counties. The National Weather Service office in Melbourne issued fresh flood warnings Thursday evening for four points along the river, warning that water had already reached first-floor level in some homes and that further rises were possible.

At Astor, in Lake and Volusia counties, the river stood at 2.7 feet Thursday night against a 2.3-foot flood stage. Near Sanford, in Seminole County, it was at 5.4 feet and closing in on its 5.5-foot threshold. Just upstream, above Lake Harney, the river had already reached 9.1 feet — well past its 8-foot flood stage — where the Weather Service said water was entering the first floors of homes on Whitcomb Drive and covering Mullet Lake Park. Farther south near Cocoa, in Brevard County, the gauge read 17.1 feet against a 16-foot flood stage and was forecast to keep climbing toward 17.2 feet over the weekend.

A storm that wouldn't move

The flooding traces back to a slow-moving rain system that parked over east-central Florida on Nov. 1 and 2. Preliminary National Weather Service totals put rainfall at 23.69 inches in Grant-Valkaria and 23.44 inches in Malabar, both in Brevard County, with Palm Bay close behind at nearly 20 inches — rainfall some meteorologists described as a 1-in-100-year event in the hardest-hit spots. Seminole County also saw substantial rain, with 8.44 inches recorded at Lake Harney and nearly 7 inches in Geneva.

The rain fell faster than Brevard County's drainage could handle. A meteorologist for WKMG News 6 in Orlando described the combination of weather factors as "the perfect recipe to conjure up a 1-in-1,000-year flood event for Central Florida," and county officials relocated 11 voting precincts away from flooded sites just before the Nov. 3 election, citing the safety of poll workers and voters.

Gov. Ron DeSantis declared a state of emergency for Brevard and several other counties within days of the storm. He later expanded that order to add Glades, Hendry, Lake, Okeechobee, Palm Beach, Seminole and Volusia counties, bringing the total to 14, alongside DeSoto, Hardee, Highlands, Indian River, Martin and St. Lucie counties, which were already covered. The amended executive order, issued out of the governor's office in Tallahassee, keeps emergency powers and state resources available to local governments as the water moves downstream. Because the St. Johns River flows north, toward Jacksonville, and drops only inches of elevation over its long course, the floodwater that fell on Brevard County in the first days of November is still working its way through Seminole, Volusia and Lake counties nearly two weeks later — and will keep doing so for weeks more.

Homes, docks and roads underwater

The practical effects are concentrated along the riverbanks rather than in the cities that sit back from them. The Weather Service's advisories listed specific effects tied to each forecast point:

• Near Sanford: water surrounding homes and covering driveways in the Stone Island area, and flooding yards and docks in the River Oaks Estates subdivision
• Above Lake Harney: water entering the first floors of homes on Whitcomb Drive between Crossover Lane and Lake Harney Road, and covering Mullet Lake Park
• Near Astor: docks and boat ramps submerged, water approaching the sea wall at Blair's Jungle Den, and Acorn, Hazelnut and Redbud roads underwater
• Near Cocoa: low-lying homes flooding in the Silver Pines subdivision and the Shakespeare Park area, Providence Road impassable, and docks flooded at Lone Cabbage Fish Camp

Seminole County's emergency operations center has been tracking the rise closely. Steven Lerner, the division manager overseeing the county's response, told Spectrum News that officials expect the river to settle into a prolonged high-water stretch rather than a quick crest and recede.

"We're anticipating reaching just between moderate to major flood stage on our rivers," Lerner said.

New projections released this past week put the St. Johns River's crest near Sanford between 5.5 and 6 feet, with Lake Harney cresting between 9.7 and 10.3 feet around Nov. 20 — figures that assume no additional rain falls in the meantime, which officials cautioned was not guaranteed heading into the back half of November.

Residents watch the water creep closer

For people who live along the river, the slow pace of the flood has become its own kind of stress. Dan Watts, whose home sits off Lake Harney Circle, told WKMG News 6 that watching the water advance day by day weighs on him more than a sudden storm would. "It sticks in your brain when you're watching the river get closer and closer to your house," Watts said.

Watts picked up 20 pre-filled sandbags from one of two free sites Seminole County Emergency Management opened — one at the Boombah Sports Complex overflow lot in Sanford, the other at the Old Geneva Volunteer Fire Station — both running from 7 a.m. to 7 p.m. Volusia County has opened a similar self-service sandbag station in Osteen. Duncan Mcelroy, who grew up along Lake Harney and still lives there, described the terrain's basic problem to Spectrum News: the river basin is flat and hemmed in, leaving nowhere for the water to drain quickly. "There's really nowhere for the water to go," Mcelroy said. "It does just flood."

What happens next

None of the four Weather Service forecast points are expected to drop back below flood stage soon. The advisories issued Thursday project the river holding near or above its current levels through the coming week, with the Melbourne forecast office due to issue updated numbers Friday afternoon and continuing daily thereafter. Seminole County officials have told residents the river is not expected to fully recede until sometime in December, meaning some waterfront homes could remain surrounded by water, and some roads impassable, for several more weeks. The Weather Service is continuing to warn drivers not to go around barricades or attempt to cross flooded roads, a caution that has accompanied nearly every flood advisory issued this month along the St. Johns River.

The slow timeline leaves emergency managers in an unusual position: there is no single moment of impact to respond to, only a gradually rising baseline that forces decisions about sandbags, road closures and relocations over weeks rather than hours. For the 14 counties still under the governor's emergency order, that means state resources, from National Guard support to debris removal funding, remain available even as the immediate storm that caused the flooding fades from the headlines. For residents along the river in Seminole, Volusia and Lake counties, it means watching a gauge reading creep upward, a few tenths of a foot at a time, for weeks to come.
