Update: Storm Agnes - when will Storm Agnes arrive today?

Storm Agnes will build today – Wednesday 27th September – hitting hardest between lunchtime and school pick-up, with experts warning people to take extra care.

People across Yorkshire are advised to batten down the hatches ahead of Storm Agnes reaching the region owing to flying debris representing a significant danger to people’s safety. Damage to homes and buildings is expected, with falling trees likely.

The weather warning is in place until 7am on Thursday, with unnecessary travel – particularly the likes of caravan towing – advised against.

It comes following a run of relatively fine days across Yorkshire, and is the first 80mph storm of the season as we head into autumn and winter.

The warning says: “A spell of strong winds is expected to move northeast through Wednesday, with a small chance that they could be significantly disruptive.”
