High winds are expected to hit the San Joaquin and Merced river basins Tuesday night through Wednesday afternoon, the National Weather Service said.
Meteorologist Jeff Barlow said the winds are expected to reach 20 mph to 30 mph with occasional gusts up to 55 mph over the higher mountain tops and along the east to west-oriented canyons.
Areas that are most prone to these winds are Shaver Lake, Yosemite Valley, Mariposa and Oakhurst, Barlow said.
The moderate to occasionally strong winds could cause trees and power lines to fall and may cause difficult driving conditions for high profile vehicles, such as campers or trailers, Barlow said.
Overnight temperatures in these areas are expected to be in the upper 30s to low 40s with day temperatures reaching upper 50s to low 60s, Barlow said.
Barlow said Fresno will experience only minor effects with winds reaching up to 5 to 15 mph.
Nighttime Fresno temperatures are expected to be in the upper 40s Tuesday with daytime temperatures in the mid 70s through Friday, Barlow said.
