Video: Seminole County FL
Seminole County's own drone and ground footage shows flooding at Whitcomb Drive and Lake Harney Road, along Mullet Lake Park Road, and at Mullet Lake Park itself. The river sits a foot above flood stage here. It would have to fall below 8.0 feet to leave flood, and the forecast does not show that happening.
The river has barely moved in a day. Its high over the past 24 hours was 9.1 feet, only a tenth of a foot above the current reading. This part of the forecast is steady.
Why it's still high two weeks after the rain
Melbourne picked up 11.51 inches of rain on Nov. 2. Only 0.18 inch fell the next day, and almost none since.
More water is still upstream. Near Cocoa, the St. Johns was in major flood at 17.04 feet at 11:15 AM ET Saturday, and it is holding near 17 feet. The Lake Harney forecast keeps the river at 9.0 feet into next week.
What's ahead
No flash flood risk is outlined for Florida through Monday. Our flash flood outlook shows risk today in Texas, Oklahoma and Washington and Sunday in Texas, while no risk is outlined from Monday through Tuesday morning. The river forecast calls for 9.0 feet to hold into next week.
What to do
- If you live on or near Whitcomb Drive: Follow Seminole County's emergency guidance. Water at 9.0 feet gets into first floors, so move valuables, medications and important papers upstairs now.
- If you drive the area: Don't enter water over a road, even if it looks shallow. Check for closures before heading toward Geneva, Lake Harney Road or Mullet Lake Park Road.
- If you planned a trip to Mullet Lake Park: Pick somewhere else. The park is covered by water.
