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. Much of this will fall on saturated ground, increasing the chances of flooding and contributing to the amber warnings we have issued. Within the amber warning areas, some could see in excess of 150mm accumulate during the event, with 60-80mm fairly widely.
