California is set to experience a heat wave over the next week, with consistently high and possibly recording-breaking temperatures for consecutive days.

The National Weather Service has forecast "dangerously hot conditions" for multiple parts of the state. Except on the immediate coastline, temperatures are expected to reach between 105 and 115 degrees Fahrenheit at different times of the day in multiple places.

The weather system responsible for these extreme conditions could bring "potentially record-breaking heat," the NWS said.

Weather experts have commented on the exceptionality of such uninterrupted heat, with forecasts showing several areas set to see little to no relief from temperatures of 100 degrees or more for five straight days.

In Sacramento, for example, temperatures are predicted to reach over 100 degrees, peaking at 112 degrees, for more than a full week, until at least July 8.

Weather watcher Colin McCarthy wrote on X, formerly Twitter, "An extreme heatwave with severe intensity and potentially unprecedented duration is about to roast California over the next week."

UCLA climate scientist Daniel Swain said in a YouTube broadcast on Monday: "This is going to be a long heat wave, particularly across inland areas. So this is going to be an event that drags on for much longer than usual for heat waves at any time of year, particularly in July. And across some parts of the northern interior part of California, it may continue essentially through mid-July."

Major California cities affected include Santa Barbara, Los Angeles, Malibu and Long Beach.

The NWS said in its most recent forecast discussion: "The duration of this heat wave is concerning as the current forecast keeps scorching conditions in place through at least the end of the week.

"This magnitude and duration of heat could pose a danger to the public if proper heat safety is not followed. This includes staying hydrated, out of direct sunlight, and in properly air-conditioned buildings. Additionally, it is very important to check on vulnerable friends, family, and neighbors to confirm their safety."

"Over 60 million residents are currently under heat-related watches, warnings, and advisories," the NWS said.

The NWS in Los Angeles has warned Californians to "be extra careful with any potential fire ignition sources, including 4th of July fireworks."

It has also said to stay hydrated, limit outdoor activities during the hottest times of the day, check on elderly neighbors and make sure not to leave pets in vehicles.

Other parts of the U.S. are also affected by the heat, namely from the central Plains to the northern Gulf Coast.

Borderland has seen searing heat recently, with some sectors experiencing multiple days with temperatures of 100 degrees or higher.

On Monday, U.S. Border Patrol agents discovered four bodies near the Santa Teresa border crossing. El Paso Times said that since May, about 20 deaths have been reported in the area.
