A long-duration heat wave will bring very hot and dry conditions
to much of the region today, lingering across interior valleys, mountains, and deserts through much of next week. The hot and dry conditions will coincide with northwest to north winds, gusting 25 to 45 mph through tonight across portions of the mountains, SW Santa Barbara coast, interior San Luis Obispo county, and the western Antelope Valley foothills. This combination along with the potential for large vertical plume growth will bring critical Red Flag fire weather conditions to these areas through tonight. Any new fire will have the potential for rapid fire spread and extreme fire behavior which could threaten life and property.
