A wind advisory was expected to remain in effect for the La Verne and Claremont region through 4 p.m. Monday, according to the National Weather Service.
Forecasters said the winds were resulting from a "north flow behind a cold low pressure system along the lower Colorado River Valley," which were bringing sustained north winds of 15 miles per hour to 25 mph, with gusts possible up to 45 mph in areas below passes and canyons.
The daytime high Jan. 7 was expected to peak in the low 60s in La Verne and Claremont, and Tuesday was expected to be about 10 degrees warmer, according to the Weather Service.
The overnight low Monday into Tuesday for La Verne and Claremont was expected in the high 30s. A storm system later in the week could bring rain showers and snow at higher elevations.
