Heat warning returning this week in Las Vegas Valley

As temperatures in the Las Vegas Valley stay well above average with lots of sunshine, the National Weather Service has released an excessive heat warning for the next few days.

Monday had a high temperature of 105 degrees. The average temperature for this date is 96 degrees, according to the weather service.

The excessive heat warning won’t take effect until 10 a.m. Tuesday and will last until 8 p.m., Wednesday meteorologist John Adair said.

Tuesday will approach a record high with 107 degrees forecast. Wednesday’s high will hit near 109 degrees before reaching 106 on Thursday and finally dip to 99 by Friday, he said.

Heat-related illnesses such as heat exhaustion and heatstroke are more prevalent during excessive heat warnings, and the weather service recommends residents stay indoors and avoid prolonged exposure or strenuous work outside.

Children and pets should never be left in cars, but during periods of excessive heat the temperatures inside a closed car can be deadly, the weather service said.

Dehydration is also a serious danger. The human body can lose up to a gallon of water per hour through perspiration, so it’s important to drink plenty of water, even if staying indoors, and avoid caffeinated or alcoholic drinks.

Midday Monday, the Clark County Fire Department reported that it had received 90 heat-related emergency calls in June’s first six days.
