This weekend's cool temperatures and higher humidity are expected to give way to more Santa Anas and a new red flag warning Monday.

The National Weather Service has issued a Red Flag waning for a wide swath of Southern California as Santa Ana winds are expected to bring dangerous fire weather to the region later this week.

This weekend will be cool with daytime highs generally below normal this time of year with the exception of mountains and deserts. The marine layer and low clouds will rebuild along the coast and some inland valleys in the evening and morning hours for the next couple of days,

Another Santa Ana wind event is expected to bring back fire danger to Southern California. Cooler temperatures are expected through the weekend as an onshore flow returns, according to the National Weather Service.
