The National Weather Service office in San Diego is warning of dangerous winds Thursday with gusts up to 70 mph in the East County mountains and deserts.
“A strong upper-level trough will bring another round of strong winds to mountains and deserts Thursday,” the weather service said. “West winds will increase Wednesday night and peak Thursday afternoon and evening before diminishing.”
“Sustained winds of 20-40 mph will gust to 50-70 mph in the wind-prone passes, desert slopes and down onto the desert floor,” according to the forecasters.
Hazards could include downed trees and power lines, difficult driving and reduced visibility because of blowing dust and sand.
The winds will also cause hazardous boating conditions for small craft late Thursday.
