Though Ophelia was downgraded from a hurricane to a post-tropical cyclone Sunday, the distinction likely matters little to the Gaels in Ophelia's path. The storm has pounded the region with 70 mph wind gusts, including one gust of 119 mph recorded on Fastnet Island, off the southern coast of Ireland, the Weather Channel reported.

"I don't want anyone to think that this is anything other than a national emergency," Leo Varadkar, the Taoiseach of the Republic of Ireland, said in a press conference Monday.

According to ESB Networks, a utility provider, roughly 360,000 of its customers are currently without power due to Ophelia.

"Stormy conditions may be tempting to watch, but big waves can easily knock you off your feet," the Japan Times reported Matt Crofts, a lifesaving manager with the Royal National Lifeboat Institution, saying Monday. "We understand why people want to experience extreme weather, but it's not worth risking your life, so we strongly urge people to respect the water and watch from a safe distance."
Despite the warnings, social media reports show daredevils living it up on Ophelia's powerful winds and rough waters.
