The National Weather Service issued a “red flag” warning Sunday morning, advising Santa Clarita Valley residents to prepare for a heightened potential for wildfires from Monday morning through late Tuesday afternoon.

During that time, a “fire weather watch” will be in effect for the Santa Monica Mountains “due to locally gusty winds, hot temperatures and low humidities,” the advisory said.

High pressures building over the Great Basin will keep the cooling onshore flows away, it said.

Temperatures of 103 to 106 are expected Monday.

“If fire ignition occurs, there could be rapid spread of wildfire that would lead to a threat to life and property,” the advisory said.

“Fire danger is expected to peak on Monday when record-breaking, triple-digit heat and widespread single-digit humidities will combine with very dry fuels,” it said. “The most critical fire weather conditions are expected across the mountains of Los Angeles and Ventura counties and Santa Clarita Valley, where a red flag warning is in effect.

Gusty winds of 20 mph to 30 mph should exacerbate the problem.

Onshore flows should start to increase on Tuesday, but the SCV still could see temperatures above 100 and humidity levels around 10 percent on Tuesday afternoon, the advisory said.

Daytime temperatures should fall to the high 80s late in the week.
