Thousands of homes lost their electricity supplies due to the intense storms which brought the heatwave to a thunderous end.
Northern Powergrid, the company responsible for the region’s power network, said some 33,222 customers across a wide area of the east coast suffered power cuts during last night's storms.
By this morning, it had successfully restored electricity supplies to 32,188 of those customers, and was working to re-connect the remainder.
The severe weather caused damage to the electricity network and power cuts for customers predominantly in the North Yorkshire, North Lincolnshire, Humberside and Teesside areas, particularly beside the coast.
Engineers successfully restored customers' power by diverting electricity through alternative routes on its network, wherever possible, and worked, where it was safe to do so, to carry out necessary repairs to the network.
Rod Gardner, Northern Powergrid’s head of network operations, said: “We’ve been closely monitoring the forecast thunderstorms for days now, and had ensured we were ready to respond if it affected our network.
“Our teams successfully restored power to some 32,188 customers across the night, and we’d like to reassure those still affected that we will continue to work until our remaining 1,034 customers still off supply at 8.30am this morning as a result of the thunderstorms have their lights back on.
“Despite facing some terrible working conditions, our teams on the ground worked tirelessly into the night, wherever it was safe to do so, in order to get as many customers as possible back on supply.
"This morning, as a result of our robust preparations, we mobilised our teams again at first light so we can continue our work to restore power for those still affected since the weather struck.
“We thank our customers for their patience whilst our teams work to carry out the necessary repairs to our network, and we’re aiming to have all customers affected by the thunderstorms back on supply this afternoon."
"We have also mobilised our helicopters this morning to carry out network inspections in the Louth, Market Rasen, Driffield and North Tees areas to help speed up the location of any damaged infrastructure.
"Whilst the worst of the weather has now passed, we will continue to closely monitor the forecast to ensure we continue to be ready to support our customers should they need us."
