While south Somerset may escape the worst of the downpours a yellow alert for rain is in place due to a forecast for downpours.
Parts of the warning area are likely to see heavy, sometimes thundery and slow-moving showers, these leading to temporary surface water flooding in a few areas, together with minor disruption to travel.
The rain is due to a slack area of low pressure moving slowly across southern Britain today, bringing unstable air and the potential for thundery showers.
The light winds mean that the downpours will be slow-moving as well as intense in some regions, with the possibility of 15 mm or more falling in less than an hour.
