An army of 400 engineers are working across Cumbria and the rest of the north west of England to restore power cut to homes affected by the atrocious weather.
Electricity North West engineers have restored supplies to 16,000 properties across the region but weather conditions are hampering restoration efforts - with some rural areas expected to be without power overnight.
In Cumbria some 5,000 properties have had power supplies restored with 1,000 remaining.
High winds and drifting snow are making it difficult for engineers to access damaged overhead lines, and to climb poles to make repairs.
Gusts of 61mph have been recorded in the northern Lake District with continuing snow showers and further snow predicted from the south and east later today with high winds predicted until midnight.
The firm has 400 engineers working throughout the region to restore power to a remaining 1,900 properties as more overhead lines teams have been called in to help from around the UK and Northern Ireland.
Elsewhere, 500 homes in Lancashire are still without power after 5,000 properties had their electricity restored. In the Peak District, 6,000 properties have electricity again with 400 still without power.
Electricity North West incident manager Chris Fox said: "Our engineers are working in atrocious conditions to restore power to affected areas but due to the worsening weather we may not be able to restore power to everyone tonight.
"We have secured additional engineering teams from the North East and Northern Ireland electricity networks however access and climbing conditions remain the main issues so some repairs may not be possible until tomorrow.
"We are continuing to work with the emergency services to highlight priority areas for restoration."
He also urges anyone without power to contact Electricity North West and stay warm until engineers can restore supplies.
"When all power cuts have been restored and the incident is over, Electricity North West will proactively notify customers who have been without electricity for more than 12 hours offering goodwill payments for the inconvenience of being without power," he said.
Electricity North West offers extra support to customers through its Priority Services Register.
Extra support is available to customers if they require it.
