Flood mapthe storm's flood footprint

Red/amber rings mark rivers that reached or came close to their own high level during the storm — the most direct evidence of likely flooding (the gauge measures the river, not any one property). Solid dots mark each flood area's reference point, coloured by the most severe warning raised there — a warning means flooding was expected. Shaded shapes are the Environment Agency's recorded flood outlines: land actually observed flooded, published retrospectively (updated quarterly). England data only.
