Homeowners with projects under construction and business owners across the Avalon Peninsula are reeling from the effects of a nasty wind storm that has seen winds gust up to 158 km/h.

At Lester's Farm in St. John's on Saturday, the winds tore apart at least five of the farm's greenhouses, ripping plants from their beds and decimating the farms plant stock.

Some major damage today, 5/17 greenhouses have lost plastic due to wind. Nothing we can't handle in time for our planting season. Stay safe! <a href="https://t.co/xVro32lkE0">pic.twitter.com/xVro32lkE0</a> —@LFM_Susan

In a note shared on Facebook, the farm's owners said that while they were able to save some of the seedlings in the greenhouses, "farming in NL [is] not for the faint of heart," In a note shared on Facebook, the farm's owners said that while they were able to save some of the seedlings in the greenhouses, "farming in NL [is] not for the faint of heart,"

Damage in parking lots

At grocery stores across the Avalon Peninsula, rogue shopping carts and cart corrals were a real concern.

The Sobeys parking lot near Long Pond was especially hard hit.

Ripped home apart in Mount Pearl

Across town in Mount Pearl, a home under construction was there one minute and gone the next.

Neighbour Trevor Menchions told CBC News that heavy winds completely decimated the roof and top floor of the home next door to him.

"We were looking out our back window and we just saw live chunks of it start to fall off," he said.

In all his time living on the Avalon peninsula, Menchions said he's never seen a wind storm of this magnitude.

"I'm staring out the back window while there's still a bit of daylight, seeing the big chunks of debris, and I'm watching cars slow down to look in because where there was a two-storey home, you've now got a one-storey with nothing."

Environment Canada says heavy winds are expected to subside overnight, while Newfoundland Power has confirmed that tens of thousands of customers throughout the Avalon Peninsula are still without power and may be until morning.
