High Wind — Lake Isabella, California

2021-04-05 · Lake Isabella, California

Event narrative

The Southern California Edison station at Grapevine Canyon Road measured a peak wind gust of 63 mph.

Wider weather episode

An upper low pressure system which dropped southward through the Great Basin on April 5 interacted with a strengthening ridge off the California coast producing a strong pressure gradient over the Kern County Mountains and Deserts. This resulted in a period of strong wind gusts between the early morning of April 5 and the early morning of April 6 when the winds diminished after the ridge built inland resuting in lowering pressure gradients. The strongest gusts occurred during the afternoon of April 5 when several stations measured gusts exceeding 40 mph. Several low impact indicator sites reported gusts exceeding 55 mph.
