Did you bother to read the accompanying text: "Scattered heavy
thunderstorms will bring torrential downpours to some places during this
afternoon and the first part of this evening. 15 to 20mm of rain is
possible, much of which could fall in a short space of time."

That seems entirely reasonable. Where I live in Surrey we've just had a
brief thundery shower, with very heavy rain for a short time. It didn't
last long enough to produce 15-20 mm, but we probably had 5mm or so.

The trouble is that many places will miss the rain, so that a broad
swath of red is rather misleading. Perhaps stippled red and green might
be better?
