Red Flag Warning could prompt PG&E to cut power to nearly 30 counties

Dry and windy weather could help any fire grow quickly and out of control this week.

SACRAMENTO, Calif. — October is a month of many changes for California weather. 

Days get shorter and often, cold fronts bring no rain, but instead, windy and dry conditions.

These patterns can set-up extreme fire weather throughout Northern and Southern California. Fires tend to grow quickly in dry and windy weather, which is the forecast starting Tuesday night for parts of the Sierra and lasting until Thursday evening for most of the Northern California region with a Red Flag Warning. 

Humidity levels will drop into the 10 - 15% range at times and wind could gust up to 45 mph for higher elevations including the foothills. If a fire starts, it will have the potential to quickly avoid containment and air attack resources may be limited if the winds are too strong.
