Storm Goretti: Hourly forecast as Met Office predicts snow

Storm Goretti - which has been named by Météo-Franceis - is due to make its arrival on Thursday, bringing with it strong winds which are likely to affect the Channel Islands and northern France.

But its impact will also be felt in Powys, where a weather warning for snow has now been upgraded by the Met Office to amber from 8pm on Thursday evening until 9am on Friday morning.

Met Office Chief Forecaster Neil Armstrong said: “Storm Goretti will be a multi-hazard event, with the most significant impacts from snow in parts of Wales and the Midlands, though rain and strong winds also have the potential to bring disruption to many.

“Goretti will bring snow on its northern edge, this most likely over Wales and the Midlands. Here accumulations of 5-10 cm are likely widely, with 15-25 cm in some places, especially hills, and perhaps up to 30 cm very locally. An Amber warning has been issued where the greatest risk of disruption is likely on Thursday night into Friday morning, though updates may be required as confidence increases in the exact track of Storm Goretti.”
