Gardaí closed access to Leitrim village after a tornado-like weather event swept through the area on Sunday afternoon causing damage to vehicles and properties.
Locals reported a freak weather event shorty after 12.30pm which blew the roof off at least one house and damaged several others.
Several cars were also damaged by flying debris, while trees were uprooted and walls were knocked over. A number of boats moored at the local jetty were overturned.
There are no reports of serious injuries, although at least one motorist received treatment for minor injuries after debris smashed into their car’s windscreen.

Willie Donnellan, a photographer who lives in the town, said he was having a cup of tea when he heard a loud bang.
“I looked out the window to my right. The next thing I saw trees disappearing and a roof flying off a house. One house was badly damaged, while the back of the pub next door was also damaged, as well as apartments across the road. Telephone poles, ESB poles were taken out of it as if there was dynamite,” he said.
“A few people were in cars which were damaged by flying debris. Part of the roof hit one. It lasted just 20 seconds, I’d say. It was frightening. We’ve never witnessed anything like this before. We had awful thunder and lightning just before it happened.”
The village was left without power for several hours after the incident.
The Garda asked people to avoid the area.
“The village is closed. Please avoid the area and be patient while emergency services deal with the incident,” the An Garda Síochána account for road traffic updates posted on social media.

A status yellow thunderstorm warning had been in place for a number of counties surrounding Leitrim as Storm Fergus swept across the region.
Small tornadoes, while rare, are associated with thunderstorms and can be caused by a change in wind direction, according to Met Éireann.
It can also cause straight line gusts of wind, which can cause extensive damage in localised settings.
Meanwhile, high winds and potential coastal flooding had been expected on the west coast later on Sunday as Storm Fergus swept across the island, Met Éireann said.
