Here’s how long LA’s upcoming heatwave will last

Residents of California may experience an early onset of summer heat, despite the fact that spring has just begun.

The National Weather Service has issued warnings of extreme and record-breaking temperatures in Southern California, with temperatures expected to be 20-30 degrees higher than normal.

“Several daily records will be broken, with some areas potentially breaking all-time records for March,” stated the NWS on Tuesday.

The intense heat is forecasted to last from Wednesday through at least Saturday, with temperatures peaking on Thursday and Friday.

“The main message is that moderate heat impacts are likely for many areas on Thursday and Friday,” the NWS reported. Los Angeles is expected to see temperatures in the 90s, approaching 100 degrees over the next seven days.

The NWS also issued a warning of a “High Risk of Heat Illness” affecting nearly 17 million people, as reported by Fox11.

The weather is expected to drastically change starting on Wednesday, with temperatures rising to 81°F after a cooler Tuesday. By Thursday, temperatures are set to soar to 96°F under clear, sunny skies.

The peak of the heatwave is anticipated on Friday, with temperatures reaching 98°F. The weekend will continue to be hot and sunny, with highs of 94°F and 92°F, respectively, extending into the following week with a high of 93°F.

This comes after a hot day during the LA Marathon, with temperatures reaching the low 80s.

A strong high-pressure system will continue to bring extreme March heat, with temperatures up to 30 degrees above normal, potentially breaking daily and monthly records in some regions.

For more details on the forecast:

• Southern California deserts and inland areas like Palm Springs may experience triple-digit temperatures, with a 25% chance of hitting 110°F next week, setting a new all-time high for March in the state.
• San Diego could see temperatures of 89-90°F, while northern coastal areas like San Luis Obispo may also reach highs near 90°F.
• Northern California will warm up later in the week, with cities like San Jose potentially hitting 90°F early next week, and San Francisco reaching the 80s.
• Sierra Nevada communities will have highs in the upper 60s to mid-70s, with ski resorts remaining in the 50s to low 60s. Rapid snowmelt will lead to increased river flow, raising the risk of flooding.

The NWS advises residents to be cautious of heat-related illnesses this week, recommending limiting outdoor activities, staying hydrated, taking breaks in shaded areas, and checking on vulnerable individuals and pets.
