Los Angeles is in the upper left of this image, while San Diego is near the center. The Santa Ana winds, also sometimes called the devil winds, [1] [2] are strong, extremely dry downslope winds that originate inland and affect coastal Southern California and northern Baja California. They originate from cool, dry high-pressure air masses in the ...
The winds drive surface water to the right of the wind flow, that is offshore, which draws water up from below to replace it. The upwelling further cools the already cool California Current. This is the mechanism that produces California's characteristic coastal fog and cool ocean waters. As a result, ocean surf temperatures are much colder ...
Prevailing winds are strongly influenced by Earth's overall atmospheric circulation, in addition to smaller-scale and shorter-lived weather phenomena. In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind ...
Red flag warnings are in place for Southern California due to Santa Ana winds that will bring gusts up to 65 mph and “extremely rare and dangerous” fire weather conditions. Red flag warnings ...
Unlike the prevailing winds in Southern California, which flow generally from west to east, carrying temperate air from the Pacific, the Santa Anas flow from northeast to southwest out of the ...
In most cases, the winds will not be strong enough to pose a high risk of trees and power lines coming down, but crosswind gusts over the passes and through some of the open areas can be high ...
A Catalina eddy is rarely prolonged. As the heat over the deserts causes air to rise, the resulting pressure gradient and increase in the normal onshore winds causes the vortex to dissipate. The result is the common local weather forecast calling for "late night and early morning low clouds and fog, followed by afternoon sunshine and sea breezes."
A major atmospheric river storm is expected to make landfall Wednesday in Northern California, moving south over the next 48 hours. It's bringing heavy rains, strong winds and significant snowfall.
