Although heavy showers are expected for many, the places across England and Wales most in need of significant rain may not see much of it in the coming days.
Most of the showers will fall across parts of north-west England, Northern Ireland and southern Scotland, with some parts of south-east England staying dry.
Where the heaviest showers do fall, there is a risk of hail, lightning and the potential for flash flooding.
Tuesday will start wet across many northern and central parts of the UK. Scotland and Northern Ireland will stay showery through much of the day, with some longer spells of rain across northeast Scotland and the Northern Isles.
