Wind speeds: The National Weather Service has issued wind warnings and alerts across much of Southern California. In L.A. and Ventura counties, sustained winds of 35 to 50 mph are expected, while gusts of 50 to 80 mph are possible. In some windy corridors, winds up to 100 mph are possible.

Gusty, dry winds — some that could reach up to 100 mph — are forecast across much of Los Angeles beginning Tuesday, and are expected to elevate the threat for fast-moving wildfires.

Winds will whip up and humidity levels will drop in Southern California this week, raising the risk for wildfires in parched areas still recovering from a recent destructive blaze

Winds began gaining strength across Southern California on Tuesday, as forecasters warned of powerful, dry gusts that could bring down trees, damage homes and bring extreme fire risk to areas that haven't seen substantial rain in months.

The NWS said winds will reach "dangerous levels" by Tuesday afternoon, hitting LA and Ventura counties. Meteorologists estimated widespread gusts of 50 to 80 mph, with isolated gusts of 80 to 100 mph across the mountains/foothills possible.
