Further details
Outbreaks of rain will become persistent and heavy on Monday night into Tuesday morning. There will naturally be some variation in rainfall totals across the area, but accumulations of 20-40 mm are likely in quite a few places, with 60-80 mm over Dartmoor and high ground in Wales. There is a chance of up to 100 mm falling over the most exposed, prone hills. Given the saturated nature of the ground, this is likely to lead to some flooding in places and transport disruption. Rain will also be accompanied by strengthening southerly winds, which may exacerbate impacts.
