New weather maps show large areas of the UK could be drenched by rain overnight. Rain could fall from England’s south coast to as far north as Belfast at midnight, according to the weather map by WXCharts.
Parts of north-east Wales and the Midlands look set to see the heaviest rain with around 5mm per hour predicted. Birmingham could see 4mm, while cities such as Southampton, Bristol, Manchester, Liverpool, Cardiff and Belfast are expected to see some lighter rain. It comes as a weather map by Surfline, which provides surf reports and coastal weather forecasts, reports a storm system crossing the Atlantic on Wednesday.
The map by WXCharts suggests rain could stretch some 320 miles from Belfast to London.
The western outskirts of the UK capital could see some drizzle, according to the weather map.
Rainfall is predicted across much of Wales (except for Pembrokeshire) and south-east areas of Northern Ireland. No rain is expected in Scotland.
Much of England’s south coast looks set for rain, from Devon to Sussex. Southampton and the Isle of Wight look set to see the heaviest rain along the coast of 3mm and 4mm per hour respectively.

A Met Office forecast for the UK for Tuesday evening and night says: “Rain will continue to move southeastwards across much of central and southern England through the night. Elsewhere will be dry, with clear spells. Temperatures for most will be above freezing, and milder in the south than Monday night.”
It says early rain on Wednesday morning will clear south-east England, with most places then set to be dry with bright or sunny spells.
“A few showers developing in the afternoon,” the forecast adds. “Feeling warm in the sunnier breaks.”
It comes as weather maps show parts of Britain could see a mini-heatwave on Early May Bank Holiday (May 5).
