Further spells of rain, heavy at times, and accompanied by strong winds and coastal gales, are expected during Monday night and into Tuesday morning. The rain should clear eastwards by around the middle of Tuesday.
The public should be aware of the risk of further disruption due to flooding.
This is an update to bring forward the end time of the warning.
Another area of low pressure and its associated fronts are likely to affect the UK during Monday night and into Tuesday, bringing a further spell of heavy rain and strong winds, particularly to southern areas from the west.
There remains some uncertainty in timing of the frontal system, but 10 to 20 mm rainfall is likely quite widely, with over 30 mm possible across parts of South Wales and southwest England. With ongoing flooding in some places, any further rain will only add to the problems. Very gusty winds may be an added hazard in places.

A band of rain, sleet and snow will spread east across Scotland and northern England on Tuesday morning. Most of the snow will be on high ground above 200-300 m where 5-10 cm may accumulate in places, but there is also a risk of some wet snow to low levels giving transient slushy deposits of up to 2 cm. Clearer weather with wintry showers will follow from the west later in the morning, but not reaching the far northeast until later in the day. The public should take extra care and be aware of the possibility of difficult driving conditions and some minor travel disruption.
This is an update to the warning issued yesterday to include northern England.
A frontal system will cross the UK from west to east on Tuesday. As it encounters colder air across northern Britain, a spell of snow is likely. This will be mainly focused across high ground, but some wet snow is possible at low levels for a time. There is some uncertainty over the final clearance time of this system from northeast Scotland as well as the extent of associated snowfall.

A band of rain, with snow on hills above 300 m, will spread east on Monday night clearing before dawn on Tuesday. As temperatures fall again, the public should be aware of the a risk of icy stretches, especially as earlier treatment may have been diluted.
This has been updated to correct the end time to late morning on Tuesday.
An active frontal system will cross Northern Ireland in the early hours of Tuesday clearing eastwards by dawn. With falling temperatures accompanying clearing skies, icy stretches are likely to form, especially where earlier treatment may have been washed off.

Showers will turn increasingly to snow on Tuesday, even down to low levels, and will continue through Tuesday night and into Wednesday morning. Accumulations of 2-5 cm are likely on ground above about 150-200 m with perhaps 10 cm or more above 300 m especially in the west of Scotland, Northern Ireland and northern England. On low ground, lying snow will tend to melt between showers by day but 1-3 cm may settle on Tuesday evening and night. Icy stretches will also reform in the evening, these lasting well into Wednesday morning. The public should be aware of the risk of some travel disruption and difficult driving conditions.
Following the eastwards clearance of the frontal system on Tuesday, a cold and unstable westerly airstream is expected to follow across northern and central parts of the UK which will persist through Tuesday night into early Wednesday. This will bring snow showers with accumulations in places.
