PG&E’s machine learning wind models are showing the potential for gusts greater than 50 mph over elevated terrain in the North and East Bay with windiest spots in the Geysers, Mt. St Helena, and Mt. Diablo reaching near or above 70 mph. With humidity dropping to 15-30% in windy areas, fire risk will increase under the strong and dry winds. The criteria for calling a PSPS event—low relative humidity, diminished moisture of vegetation, and gusting wind conditions— are forecasted to be met on Tuesday night.
Given these conditions, PG&E activated its Emergency Operations Center (EOC). As of 3 pm on Monday, 11/4, 20,142 customers in 17 counties and 4 tribal areas are in scope for this PSPS event. Of the ~20,000 customers in scope, they are primarily located in Western Sacramento Valley, North Bay, and Elevated terrain in the East Bay.
