A month's worth of rain is expected to fall over 30 hours today and tomorrow, the Met Office warns.

Snow showers will also hit parts of northern Britain today as the first 'significant' mountain snow of the season arrives.

Met Office forecaster Aidan McGivern said 100 to 120mm of rain is possible over the peaks of Snowdonia and the Brecon Beacons in Wales.

The organisation has changed its flood warnings for today and tomorrow, with one alert for Wales raising the prospect of 'danger to life' flooding.

The yellow weather warning will be in force from noon today until 6pm tomorrow.

Two other rain alerts have been issued for south-west and north England.

They will both be in force from 3pm today until the same time tomorrow.

Meteorologists predict flooding for south-west England as up to 90mm of rain hits higher areas and wind speeds reach 50mph.

The northern warning zone stretches from Sheffield to County Durham, with forecasters again saying 'danger to life' flooding is possible as up to 70mm of rain falls in the area.

The average total rainfall for October in the UK is 127mm.

There will also be a north-south divide in temperatures today as polar air washes over northern Britain, while tropical area sweeps across the south.

The Environment Agency's five-day flood risk forecast states: "Local flooding is possible from rivers and surface water across Wales and parts of northern, central and south-west England later on Friday and on Saturday.

"Local river flooding may continue through Sunday and into Monday on some longer, slower-responding rivers. Properties may flood and there may be travel disruption."

A spokesman for added: "There is warm air pushing north over Europe, from Africa up to Scandinavia, plenty of energy and there has already been atrocious weather in the Mediterranean with flooding for Spain and Italy.

"There is also a push of cooler then colder air from the north-west wrapping around the low pressure north of Scotland. A large temperature contrast and this strong frontal band bringing the likelihood of flooding.

"By day (on Friday) the temperature contrast will be stark, 6C in the north, low to mid-teens in south. For a time on Friday evening there could be some snow for the higher routes of Cumbria and Yorkshire."
