While most of Southern California experienced extreme heat on Wednesday, some areas were also battered by the kind of wild weather that was blamed for the death of at least one person the previous day.
An excessive heat warning was in effect in Los Angeles and Ventura counties, as soaring triple-digit temperatures were once again predicted in the valley areas and at lower elevations in the mountains, according to the National Weather Service.
The warning was scheduled to expire Thursday evening, with slightly cooler temperatures forecast for Friday and Saturday.
Triple-digit highs were also expected in the valley areas of San Bernardino and Riverside counties, prompting the weather service to issue a heat advisory for the region.
Meanwhile, monsoonal moisture was expected to bring more thunderstorms to the mountain and desert areas on Wednesday afternoon, according to forecasters.
The storms were capable of producing locally heavy rainfall and flash flooding, along with mud and debris flows in recent wildfire burn areas, the weather service stated.
As a result, a flash-flood watch that was issued on Tuesday remained in effect on Wednesday and was expected to last through Thursday evening. The affected areas included the valley and mountain areas of Riverside and San Bernardino counties, and the Apple, Lucerne and Coachella valleys.
Thunderstorms and flooding resulted in the death of a hiker in Forest Falls and the rescue of multiple people in San Bernardino County on Tuesday.
Video sent by a KTLA viewer showed hail hitting the Beaumont area late Tuesday afternoon. A lightning storm also lit up the night skies over Victorville around midnight, leading to a stunning though scary sight for residents and passing motorists.
Thunderstorms were forecast to hit inland areas through Thursday.
