Late-night Christmas street markets have been abandoned in Truro because of the storm lashing the region.
The farmer’s market on Lemon Quay should have stayed open until 9pm but will now close at 3pm today amid public safety fears.
The market that was due to take place on Boscawen Street this evening has also been called off by organisers.
Nigel Ekins, chairman of Truro farmer’s market, said it was only the fourth time in 16 years the market had been forced to close by bad weather.
He said: “The forecasts are for high and damaging winds and leaving these stalls up would be unsafe for the public.”
Mr Ekins said the closure was a tough decision on the last late-night shopping event before Christmas.
“It’s the time of year when everybody was hoping to boost their turnovers,” he said.
A spokesman for the Truro business improvement district confirmed the Boscawen Street market would not be set up this evening.
The spokesman said: “The usual road closures will be in place and there will be scheduled street performers all over the city throughout the evening.
"The only element that will not be running is the street market on Boscawen Street due to the high winds.”
All Skybus flights to the Isles of Scilly from both Land's End and Newquay have also been cancelled for today.
More severe weather is forecast to hit the county on Friday and Saturday.
