Live blog: Storm Agnes impacts UK and Ireland

Storm Agnes impacts the UK and Ireland through today. Follow our live blog as we keep you updated.

Ireland has seen the worst of the conditions through today, with trees being felled, blocking road access in southern areas which saw the strongest gusts.

Flood warnings remain in place along much of the Welsh coastline away from the south with 19 flood alerts and warnings in place across southern to central Scotland. Another cluster of flood alerts remain in place in Cornwall and the northwest of England.

An arch of supercells are moving across the Irish Border and also into Wales this afternoon, likely to be producing severe wind gusts and torrential downpours with potential tornadoes even forming. This is visible below on the WeatherRadar.

Agnes is now impacting south-west England with a power cut reported on the Isles of Scilly.

Power outages are still being widely reported across Ireland, with large waves reported along the north coast of Dublin too.

Damage to buildings in southern Ireland have been reported with a roof ripped off a building in Cork. Wind gusts have now come down a notch here from 67 mph to around 60 mph, albeit still strong, while also strengthening now across south-west England.

Trees have been downed with roads flooded across southern Ireland.

A calmer start for many eastern areas, however Agnes is already starting to bear down on southern Ireland with large waves brewing out at sea.

ESB Networks are reporting power cuts already across southern Ireland, with almost 2,000 people currently impacted. Aircraft are also having to divert with difficulty landing in Cork in the high winds.

Strong winds, heavy rain and large waves are expected, particularly through Irish Sea coasts from first thing Wednesday morning, with winds strengthening as the day goes on. Flood alerts are also in force across several coastal areas.

Agnes underwent explosive cyclogenesis last night, which is when there's a rapid fall in pressure in the centre of the low (usually 24 mb/hPa in 24 hours) and can lead to violent winds.

With Agnes, the pressure fell from 996 hPa to 970 hPa, which is an astounding 26 hPa in just twelve hours.
