...The Flood Warning continues for the following rivers in Florida...
Withlacoochee At US 41 Dunnellon affecting Marion, Levy and Citrus
Counties.
.The Withlacoochee River at Dunnellon has been steadily rising since
July, and on September 15 reached flood stage. The cause of the high
water along the Withlacoochee River at Dunnellon is due to excessive
hydrilla growth (from the river bottom to the water surface) along a
4.5 mile stretch of river between US 41 and Lake Rousseau. The
hydrilla is acting like a dam and holding water back, causing water
levels to rise.

Each image is a preview of a whole Sentinel-2 tile — an area of roughly 110 by 110 km, where one pixel is about 320 metres — not a close-up of the event, which may be a small part of it. "Clear" means under 30% cloud across the entire tile, so the exact place that matters can still be hidden. These are pictures for context, not an assessment of damage.
