A broad area of persistent heavy rain is expected to move northeast across this region between mid-Tuesday and early Wednesday, and may be accompanied by gale force winds across the southwest of England for a time.
Heavy showers will likely follow in the wake of this rain during Wednesday, with these probably being heaviest and most numerous close to the Bristol and English Channel coastlines.
Through the combination of both the rain and following showers 10-20 mm of rainfall is expected widely across southern England and parts of southern Wales, with the potential for 40-60 mm in some isolated locations, especially across the high ground and locations that see the greatest number of showers.
