Heat Advisory Covers Central Coast Through Monday as Sundowner Gusts Threaten Highway 101

A persistent western high-pressure ridge is driving prolonged daytime heat and warm nights with an eastward shift expected to bring gradual relief early next week.

Overview

A heat advisory remains in effect for most of the Central Coast through 8 p.m. Monday because a strong upper-level ridge is keeping temperatures above normal.
Forecasts show near-surface temperatures rising each day into the weekend with the hottest conditions expected before the ridge weakens.
A tightening northerly pressure gradient will produce Sundowner offshore winds tonight with gusts near 50 mph that can create dangerous crosswinds for high-profile vehicles on Highway 101 between Gaviota and Goleta.
Local health officials warn of a moderate to high risk of heat illness for very young children, elderly residents, people without air conditioning, and anyone working or exercising outdoors.
Models project the ridge will shift east early next week allowing gradual cooling and a likely end to advisories, but above-normal temperatures may linger and another hot period is possible by the end of next week.
