A tornado warning has been issued for Herefordshire.
From TORRO (The Tornado and Storm Research Organisation):
“Storm Darragh will push a frontal system across the area this evening and overnight.
“The cold front will tend to split, with the surface portion lagging behind the upper part.
“This will encourage a shallow moist zone to develop.
“A dry intrusion along should overspread this, especially across the southern half of the indicated area.
“Hi-res models suggest a broken line of shallow convection developing along the surface cold front, which could evolve into shallow supercells.
“Instability is very modest, but the shear through the potential depth of such convection could allow rather strong dynamically-augmented updraughts to evolve.
“Wind gusts to around 70-75mph could accompany the stronger cores, and one or tornadoes are possible too.
“Please note the larger-scale high winds from the storm are covered by the relevant national met service warnings.”

Storm Darragh will bring periods of heavy rain to south and mid-Wales through Saturday.
20-30 mm of rain will likely fall in 3-6 hours, with totals of 80-90 mm likely by the time rain begins to ease on Saturday evening. Given recent wet weather, coupled with very strong winds from Darragh, impacts on travel and infrastructure are likely.
