This morning kicks off a week of humid and stormy weather around Southern California.

Showers and thunderstorms are expected this week in the mountains, deserts and valleys around Southern California, according to the National Weather Service. Thunderstorms could bring brief moderate to heavy showers as well as gusty, erratic winds. Low-lying areas could be at risk of flooding. Officials are especially concerned about dry lightning that could spark wildfires.

"And the possibility of getting some really gusty and erratic winds from thunderstorms, which — if a fire does start — could spread the fire pretty quickly," NWS spokesman Rich Thompson told KPCC.

Beach-goers or hikers should exercise caution, and pack it in if there is any sign of a thunderstorm developing.

Today it will be in the 70s near the coast, 80s inland and 90s in the valley. The Antelope Valley could reach 100.
