Heavy snowfall is expected across parts of central and southern England and south-east Wales late Tuesday and on Wednesday. Accumulations of 5 to 10 cm are expected widely, with locally 10 to 15cm in central parts where there is a moderate risk of over 25cm. This is expected to cause disruption to transport networks and could lead to problems with power supplies. Outdoor events and activities could also be affected by the snow.
This early warning is expected to be superseded by Flash messages.
