As per the UK Highways Traffic Sign Manual Chapter 4 - Warning Signs page: 57 The following advice is given:

10.1.2.  The “Flood” sign to diagram 554A (S13‑2‑2, see Figure 10-2) may be displayed only for as long as the hazard continues to exist or is expected to recur in the near future. It may be accompanied by a distance plate with or without an arrow as appropriate and should be followed, beyond the flooded length of road, by a “Try your brakes” sign to diagram 554.1 (S2‑2‑39, see Figure 10-3). If the water depth makes the road impassable, a “ROAD AHEAD CLOSED” sign, placed at each end of the closure at junctions where traffic can be diverted, would be more appropriate.
