LONGVIEW, Alta. - RCMP say extremely high winds have caused four semis to roll over on a highway in southwestern Alberta.

Emergency personnel from the Crowsnest Pass are at the scene south of Longview on Highway 22.

RCMP say the wind is even making it hard for officers to investigate the carnage created by the high-gusting winds.

"Winds are very excessive in the area," said Const. Tom Christie.

"RCMP members are having difficulty standing on the road to investigate and assist because of the wind.

"So far there have been only minor injuries to vehicle occupants."

"Southern Alberta - WIND WARNING for Crowsnest Pass, Pincher Creek, Waterton Lakes, gusts 100+km/h possible: http://bit.ly/ZbkVkW #abstorm," said @daynavettese.

Environment Canada is warning that wind gusts exceeding 100 kilometres an hour are possible in the area.

Truck drivers are being urged to stop until the winds calm down.

I jumped out of my car and ran down to the beach. To my surprise, there were still several beach-goers taking in the sight of this massive shelf cloud, as well as a few surfers in the water, trying to catch one last wave. Of course, there was a Volusia County lifeguard standing there watching over everyone. I walked down to the water and took some shots, always keeping an eye on the lifeguard. As the shelf cloud approached, I swung back behind the guard tower, waited for him to climb up it and signal to the surfers to exit the water. I took several shots, then hopped back in my car and tried to stay south of the storm."

This is one of many examples of how a completely unplanned photo wound up being among my best photos."

I barely had time to get back to my car before it hit and I was engulfed! The darkness was surprising but it only lasted about 10-15 minutes before it thinned out enough to where I could drive back home, only about 2 minutes away. This was the giant haboob that made national news when it rolled through and entirely covered all of Phoenix and some surrounding cities."

The storm that blew through started off with an incredible amount of lightning and then dumped a significant amount of rain in a short amount of time -- on the other side of the river. DC got drenched and Arlington didn't see a drop."

    (<a href="http://pmm.nasa.gov/articles/extreme-weather-photo-contest-winners" target="_hplink">Brian Johnson / NASA</a>) "The National Weather Service had warned about a large scale Derecho forming and moving through. This spawned a couple brief severe thunderstorms that dumped hail on rush hour traffic before the main line moved in. As the bigger storm moved into the Wichita area, reports were coming in of 70 mph winds and hail. There is an open farm field roughly two miles from my house that I shot lightning on the previous night. I sat there for about 20 minutes before this large squall line pushed through the clouds. I was hit with a pretty good gust front as it got closer, but as the winds increased, I decided to get to shelter. This photo was one of the last ones I took."
