A flash flood
im pretty sure that its "throng." this is because to rush, melt, and flood are all actions done by water, and "throng" does not mean this.
The Severn Bore.
A flood can do major damage. The most critical time is that time before the water makes it impossible to save what might be saved. People, property and livestock might be saved by moving them to higher ground or out of the way of the flood. Before the flood occurs, many preparations for a flood can be done with no rush or pressure. When the flood arrives, it is most important to save lives. What can't be saved will be lost.
