UK tourists heading to USA warned 'threat is real' and told 'take it seriously'

UK tourists and holidaymakers have been warned over journeying to the United States amid a deadly US heatwave. Brits are among hundreds of tourists flocking to Death Valley despite a deadly US heatwave, Sky News has reported this week.

Dozens of locations in the west and Pacific Northwest broke previous heat records over the weekend. The United States is also expected to see high temperatures throughoutt he coming days, with four deaths in Portland amid skyrocketing Oregon mercury levels.

English, French, Spanish and Swiss tourists headed to take photos of the barren landscape, known as one of the Earth's hottest places, on Monday. Officials in the park urged visitors to stay safe, with park superintendent Mike Reynolds warning "high heat like this can pose real threats to your health".

Nearly 70 million people are under heat alerts, after over three dozen high-temperature records were either set or tied on Saturday, according to the National Weather Service. “In the West, intense widespread dangerous heat will continue through early next week,” the weather service said. “All-time heat records may be possible in a few locations.”

On Saturday, Death Valley reached 128 degrees, breaking the daily record of 127 set on July 6, 2007. Las Vegas reached 115 degrees, tying with records in 2007 and 1989. Kingman, Arizona, reached 109 degrees, breaking the previous record of 108.

Extremely dangerous heat is expected to persist in the West, with excessive heat watches, warnings and heat advisories in effect for much of the region. Heat warnings are active in California and Nevada due to the increased risk of heat-related illnesses there.

“Intense, widespread, and long duration heat building in the West will be extremely dangerous and potentially deadly if not taken seriously,” the weather service said in a warning issued to UK tourists heading abroad.
