UPDATE: The high winds are still causing problems with 70 homes without power in Carn Brea, Pool.
A spokesman for Western Power said: “They have been without power since 6am and are currently being dealt with.”
The adverse weather also kept the fire service busy, with a crew from Camborne called to remove fallen trees last night.
Firefighters first attended a reported tree on a delivery van in Falmouth and then cleared a fallen tree blocking the road between Scorrier and St Day. Fallen trees were also removed from The Forge estate in Carnon Downs, and Chapel Hill, Truro.
Gale force gusts and big swells also kept Falmouth coastguard busy.
The coastguard rescue team were called to a report of a square rigged vessel around the foot of the cliffs at Stack Point. Once on scene they found our that the vessel was in fact a garden gazebo.
Both the coastguard and the town's inshore lifeboat also guided a 16ft punt ashore after it had drifted to the visitor yacht haven off the Prince of Wales Pier at 7pm.
SEVERE weather across west Cornwall left homes without power last night as high winds brought down power cables.
The high winds were causing problems until early this morning, with Penzance Community Fire Station called at 6.00am to respond to a blown transformer at Penberth Cove, near Porthcurno.
Western Power reported that hundreds of homes across the region were affected by the power failures, including St Buryan, Mousehole, Newlyn and Penzance, where 100 homes in the Heamoor area had no electricity - live cables carrying up to 53,000 volts and 11,000 volts were said to be cut off.
Yesterday evening Western Power said that they were prepared for the weather conditions.
The service reported its team was working in "dangerous conditions" with winds of up to 70mph and heavy rain.
A spokesperson said this morning: "We have had numerous faults across Cornwall.
"We have worked through the night."
The adverse weather also prompted police to warn motorists of potential hazards and to be extra careful on the roads, with a fallen tree on the A30 at Laity Lane in Lelant reported at 8.20pm.
The MET Office issued a yellow warning of rain yesterday evening.
The power supply is said to be back this morning.
