Windy conditions are expected for the Santa Barbara County mountains and South Coast areas beginning Friday afternoon, with warm temperatures are on tap for the weekend.

A Wind Advisory will be in effect from 5 p.m. Friday until 4 a.m. Saturday, with forecasters predicting northwest to north winds of 15-30 mph and gusts up to 45 mph, according to the National Weather Service.

Affected areas include Santa Barbara, Montecito and Carpinteria, as well as the San Marcos Pass and the San Rafael and Dick Smith wilderness areas in the backcountry, according to the NWS.

In addition, the strongest winds are expected in the foothills west of Goleta, according to the advisory.

“Gusty winds will blow around unsecured objects and make driving difficult, especially for high-profile vehicles,” the advisory said. “Gusty crosswinds may develop on area roadways.”

Breezy conditions may occur on local roadways, including areas on Highways 101, 154 and 192, according to the advisory.

“Tree limbs could be blown down and a few power outages may result,” the advisory said. “Use extra caution when driving, especially if operating a high-profile vehicle. Secure outdoor objects.”

Mostly sunny skies are expected through the weekend, with daytime highs in the low-80s and overnight lows in the low-60s on the South Coast.

The NWS issued an Excessive Heat Warning that will be in effect from 10 a.m. Sunday through 9 p.m. Monday for much of the Santa Barbara County mountain areas, including the San Marcos Pass, as well as the Dick Smith and San Rafael wilderness area.

The weather forecast for Sunday and Monday is sunny for the county’s mountain areas, with highs starting around 95 degrees and rising to 103 at low elevations, and in the mid-80s to lower-90s at high elevations. 

Some areas of the county’s mountains could hit triple-digit temperatures in the valley and foothill areas.

Forecasters predict “dangerously hot conditions,” with possible highs up to 105 degrees during the heat warning period.

“Young children and pets should never be left unattended in vehicles under any circumstances,” the weather service said. “This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.”
