The Environment Agency currently has 4 flood messages within 25km of a point in the middle of Dacorum. The desk is publishing an original summary, not the full warning text.
Named catchments on this run: Upper River Colne and Radlett Brook; Lower Lee tributaries; Silk Stream and the Deans, Edgware, Dollis, Mutton, Wembley and Wealdstone Brooks; River Pinn and Woodridings Stream. Some of those watercourses sit over the borough boundary. A watch near London Colney or Edgware is still useful context for anyone driving the A41 or living on the Gade.
If you are on a floodplain, use Floodline 0345 988 1188 and the Environment Agency map. Do not wait for a newspaper to tell you the river has come up.
Comments are coming. Until then, write to hello@dailynetwork.co.uk.
