This weekend, an exceptional heat advisory has been issued for some areas in Southern California.

On May 9 and 10, extreme heat is forecasted, with temperatures expected to exceed 100°F, particularly in the Antelope Valley, Inland Valley, and Inland Empire.

Meteorologists predict that this could be the hottest day of the year so far. This heat wave is unusually high compared to the typical spring temperatures in Southern California.

Generally, from March to May, Southern California gradually warms up as it transitions into summer weather, but temperatures reaching 100°F are usually seen only in July and August.

In particular, this heat wave is expected to intensify due to the strong influence of high pressure. The high pressure is lingering over Southern California, blocking the influx of cool marine air and rapidly increasing temperatures in the atmosphere. As a result, the perceived temperature in some areas is expected to soar above 105°F.

Experts are urging special caution for vulnerable populations, including children, the elderly, and those with cardiovascular diseases. They recommend avoiding direct sunlight when going outside, staying hydrated, and using air conditioning indoors. Authorities are already operating cooling centers in some areas and have prepared emergency plans for potential power outages or air conditioning failures.

Meanwhile, power demand is expected to surge due to this heat wave. California's power authorities are asking residents to minimize electricity use by setting air conditioning temperatures higher and refraining from using large appliances during the day.

The heat wave is expected to continue until Monday, with temperatures gradually decreasing from mid-week onward.
