Flash floods tear down Las Vegas strip leaving casinos and gamblers soaked as storms batter the city

Casinos and hotels are semi-underwater as flooding in Las Vegas forces punters to seek shelter from a rare thunderstorm.

The footage came as flashfloods hit downtown Vegas on Thursday night, following warnings from the authorities that the storm was on its way.

The iconic Caesar’s Palace was flooded, online video seemed to show. 

Water is shown pouring through the roofs of a casino and soaking the carpet while and people were filmed drenched by the torrential rain.

Cars wade through floodwaters near the Strat Hotel in downtown Las Vegas in another video while a woman gasps in shock.

'Electric surges set the fire alarms of several buildings off, causing fire responders to have to head out into the storm to respond to them,' Las Vegas resident Alexander Wolf told  The New York Post.

Some vehicles were almost fully submerged in the floods, the footage showed.

There was also flooding inside Planet Hollywood on the Las Vegas Strip, with water coming through the room of the building.

Footage shows a torrent of water cascade through the roof after the storm dislodges one of the panels, according to punters who allegedly filmed the bad weather.

Another panel gives way, prompting shouts from the crowd below. 

Authorities issued a flash flood warning and severe thunderstorm warning for the las Vegas Valley early Friday morning.

Hotel residents filmed their yards filling up with water as rain battered the doors and windows through the night.

The monsoon season in Nevada happens between July and September, although flashfloods in Vegas itself are rare.

No injuries have yet been reported.
