Winds were whipping flags and ripping the remaining leaves from trees Thursday as the Sacramento region experienced a breezy afternoon.
Sacramento airports had all registered winds blowing at more than 20 mph by noon: Sacramento International Airport, 33 mph with gusts to 43, Mather Airport, 21 mph with gusts to 29, Sacramento Executive Airport, 23 mph with gusts to 33, and McClellan Airport, 22 mph with gusts to 28.
The National Weather Service notes that the gusty conditions are caused by high pressure over Oregon and Nevada. Winds blow from high pressure to low pressure, much like going from a hilltop to a valley on a topographic map.
A wind advisory remains in effect Thursday until 10 p.m. with moderate to strong north to northeast winds. A wind advisory means that sustained winds of 25 mph or gusts of 40 mph or more are expected.
