The National Weather Service is warning Angelenos of extreme highs later this week of 100 to 110 degrees in “all areas” between five and 10 miles inland from the coast.

The weather service is warning of a high risk of heat-related illnesses and urging residents in the region to prepare for “a long-duration heat event, during which several daily records will likely be broken.” Even coastal cities were forecast to reach highs of 90 degrees. The Oxnard-LA weather service office added that nearly the entire forecast area was “very likely” to be under heat advisories or extreme heat warnings for the Wednesday. (National Weather Service) A long-range forecast from the weather service predicted grim news for anyone seeking relief from the heat: “The only real question for the [Wednesday] through [Friday] The forecast is: Will it be very hot or very hot?” In central Los Angeles, highs reached 96 degrees on Sunday. Between Sunday and Wednesday, forecasters said, there is a 30% to 40% chance of highs of at least 110 degrees in the San Fernando Valley and a 50 to 50 chance of highs of at least 100 degrees in central Los Angeles. “For much of Los Angeles, this will likely be the temperature higher. [week] of the year,” said Ryan Kittell, a meteorologist with the National Weather Service in Oxnard. “It’s going to be hot on Monday, then it’s going to get really hot on Tuesday. … In the valleys, we’re seeing between 100 and 110.” Along the coast, Kittell said, “highs between 80 and 90 degrees are expected, even in beach areas.” Whenever temperatures reach this range, the weather service urges people to drink plenty of fluids, stay in air-conditioned rooms when possible, stay out of the sun, check on the well-being of family and neighbors and be alert for the threat of fire. As usual, some of the increased heat on Earth will be at Furnace Creek in Death Valley, where the high temperature was 121 degrees.

It’s high pressure in the air, causing a phenomenon meteorologists call “compressive warming.” An “additional ingredient” to all of this, Kittell said, “is that the winds will shift and become a little more northerly.” Although this high-temperature cocktail doesn’t include the Santa Ana winds, Kittell said, “we have a history of big fires when it’s this hot.” weather service. A heat advisory (in effect for central Los Angeles until 10 a.m. Tuesday) means some groups may be particularly vulnerable to the heat. An extreme heat advisory (in effect from 10 a.m. Tuesday to 8 p.m. Friday) suggests we are approaching something even more dangerous: an extreme heat warning, which means dangerous heat is occurring or is about to occur, putting everyone at risk, Kittell said, these are days to be very careful. Plus, “we’ll probably fill the kiddie pool in the backyard,” Kittell added.
