Update — November 7, 2026, 8:03 p.m. Central:

The National Weather Service’s evening forecast calls for the St. Johns River west of Cocoa, Florida, to rise into major flood stage over the next couple of days and crest at 17.1 feet by midweek. The gauge measured 16.9 feet at 8:15 p.m. Eastern Standard Time Saturday, with moderate flooding occurring.

The bulletin describes home flooding and impassable access roads at a higher, 17.2-foot impact threshold. That threshold is not the current reading or a confirmed account of damage at every listed location.

Near Sanford, a revised forecast delays the expected crossing of the 5.5-foot flood stage to Sunday evening and projects 6.3 feet Thursday evening. Near DeLand, the river is now expected to exceed its 4-foot flood stage Sunday evening and reach 4.3 feet Wednesday evening. These replace the earlier timing and peak forecasts retained below.

The warnings continue until further notice. Motorists should avoid flooded roads and barricades, and people near riverbanks should exercise caution, the weather service says.

Earlier Reporting — November 7:

The National Weather Service continued flood warnings Saturday for several stretches of Florida’s St. Johns River, with moderate flooding already occurring near Astor and above Lake Harney and further rises forecast near Sanford and DeLand.

The Melbourne office’s November 7 statements describe different conditions at separate river gauges. Their readings use local flood-stage thresholds and should not be treated as directly comparable water depths along the entire river.

Near Geneva, above Lake Harney in Seminole County, the river measured 9.1 feet at 10:30 a.m. Eastern Standard Time Saturday, compared with an 8-foot flood stage. Forecasters expect a rise to 9.6 feet Thursday morning, November 12, with additional rises possible afterward.

At the 9.5-foot threshold described in that bulletin, water begins entering homes in low-lying areas along the river, with flooding around Black Hammock near Lake Jesup. That is a stated impact threshold, rather than confirmation that all those homes were already flooded Saturday.

Near Astor in Lake and Volusia counties, the river stood at 3 feet at 9:30 a.m. EST, above its 2.3-foot flood stage. The forecast calls for levels around 3.2 feet, with moderate flooding continuing into early next week.

Near Sanford, the river was at 5.3 feet at 10:30 a.m. Saturday, below its 5.5-foot flood stage. It is forecast to cross that threshold Sunday morning and reach 6.2 feet early Wednesday afternoon, November 11.

Near DeLand, a 9:30 a.m. reading of 3.9 feet was just below the 4-foot flood stage. The river is forecast to rise above flood stage shortly after midnight Saturday night and reach 4.4 feet early Thursday morning.

The warnings continue until further notice. The weather service advises motorists not to drive around barricades or through flooded areas and urges caution near riverbanks.
