Counted from the Environment Agency's warning record for England (2–4 October 2019). Welsh warnings are held in a separate record and are not counted here, and FloodRadar only began recording Scottish warnings on 16 September 2026 because SEPA publishes no archive. So this is England's share of the storm, not its total.

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. An unshaded area means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record.
