Strong Wind — Imperial County West, California

2023-04-03 · Imperial County West, California

Event narrative

Semi truck rolled over along SR-86, just south of Salton City, injuring the driver. The two southbound lanes on the highway were blocked. Winds at the time estimated to be 35-45 mph.

Wider weather episode

An anomalous upper-level low pressure system moving in from the eastern Pacific moved across the west coast of the United States. This resulted in a tightening of the pressure gradient and thus strong westerly winds across portions of Imperial County, especially the western half of the county, where widespread gusts of between 50-70 mph along with areas of blowing dust significantly reducing visibilities were observed.
