While some area residents spent the night outdoors enjoying the dip in temperatures after a hot day on Sunday, many braced for the scorching weather moving into the Southland.
A red flag warning was issued at 4 p.m. for several parts of Southern California, including the Santa Clarita Valley. It is expected to last through at least 9 p.m. Tuesday. The warning predicted highs of up to 108 in Santa Clarita Monday and 110 Tuesday.
Gusty winds and the forecast of triple-digit heat increases the danger of brush fires.

Los Angeles County firefighters are putting extra crews on duty and preparing for tough conditions.
"We're looking at, over the next couple days, temperatures increasing well over 100 degrees, humidities dropping and possible wind increase," explained L.A. County FD Capt. Bill Whalen.
The heatwave also poses health risks. Residents plan to spend the next couple of days in air-conditioned places.
