Sept. 12--After enduring nearly a week of extreme heat, Southern California is now expecting rain beginning Sunday.
According to the National Weather Service, a storm could produce more than an inch of rain in some mountain areas, less in the L.A. basin.
Mudflows in burn areas and flooding in low-lying areas are possible. There's a 20% chance of showers in some areas Saturday, including Santa Barbara.
Friday saw more sweltering temperatures, including a few spots that set records for the day.
Saturday will see a slight cooling trend, with highs in the 80s in the L.A. area and 90s in the inland valleys.
The heat has been particularly stubborn at night. Because of warm ocean temperatures and high humidity, it barely cooled off overnight, and shade and wind can't help those without air conditioning, the National Weather Service said.
The heat wave brought power outages and other problems this week.
