Amber weather warnings have been issued for parts of north-west England and Northern Ireland as Storm Debi hits the UK, bringing heavy rain and strong gale-force winds.
Power outages have been reported across the island of Ireland, with tens of thousands of homes left without power after the storm made landfall overnight.
The Met Office has issued several weather warnings for Northern Ireland, including an amber warning for wind, which will remain in force for the south-east of the region until midday.
Much of the Republic of Ireland is covered by a red wind warning, the highest level of alert, which came into force early in the morning and will last until 9am, with an orange warning that will last until 10am. tomorrow in some parts.
In north-west England, the Amber Alert is active from 10am to 4pm on Monday and covers coastal areas north of Liverpool to Whitehaven.
The Met Office has warned people in those areas to beware of strong, disruptive winds with the potential for flying debris.
