High winds caused problems across the region last night.

The A66 has now reopened to high-sided vehicles but the The A19 Tees flyover remains closed and crews from High Handenhold Fire Station have been dealing with a dangerous structure in the Pelton area.

The Met Office says winds gusted as high as 87mph last night and a yellow weather warning is in place across the North East coast from the Borders to Lincolnshire for the next 24 hours: "A spell of very windy weather is expected during Wednesday, with the west to northwesterly wind likely to gust 60 mph in places, locally 75 mph over high ground. Some disruption to road travel is likely, including restrictions on bridges.
"The strongest winds will affect some of the higher level roads, for instance those over the Pennines and the Southern Uplands. However, the northwesterly winds will also be very strong and gusty at lower levels too, including in areas to the east of high ground."
