Downtown Los Angeles is starting Saturday near 69 degrees, but the city is headed for a hot, dry afternoon with a high around 91. A Heat Advisory remains in effect through Saturday evening, while the bigger fire-weather concerns are focused in Santa Ana-prone parts of Los Angeles and Ventura counties.

Heat And Fire Weather Peak Saturday

The National Weather Service expects mostly sunny skies and very dry conditions across the region, with the Heat Advisory lasting until 8 p.m. Saturday. In higher-risk areas, a Red Flag Warning also remains in effect through 8 p.m., with wind gusts of 30 to 50 mph and humidity dropping as low as 8% to 20%.

That combination can make any new fire grow quickly. Residents should avoid activities that could create sparks, drink plenty of water, limit strenuous time outdoors during the hottest part of the day, and check on neighbors or relatives who may be more vulnerable to heat.

Cooling Arrives Sunday

The weekend turns noticeably more comfortable Sunday, when the high is expected to reach 86 degrees under sunny skies. Monday should be sunnier and cooler still, with a high near 82 and an overnight low around 61.

Rain Chances Return Tuesday

Tuesday brings a high near 74, with a slight chance of rain showers after 5 p.m. Rain chances increase Tuesday night, and Wednesday looks like the most unsettled day of the week, with showers and thunderstorms likely and a high near 69.

Showers could linger into Thursday before 5 p.m., followed by partly sunny skies and a high around 68. By Friday, the forecast calls for sunny conditions and a modest rebound to about 71 degrees.
