Storm Claudia will bring very heavy rainfall to a large swathe of central and southern England and Wales on Friday into Saturday. This rain will become slow moving and some areas could see up to a month's worth of rain in 24 hours.

Within the amber warning areas, some could see in excess of 150mm accumulate during the event, with 60-80mm fairly widely.
