NORTHERN CALIFORNIA – PG&E is warning several customers of a potential public safety power shutoff (PSPS) Wednesday through Friday due to a possible wind event.
The PG&E Emergency Operations Center said it has been activated to prepare for a possible Diablo wind event lasting Wednesday through Thursday, aside from the Northern Sierra that may experience the winds through Friday morning.
Officials with PG&E said the current forecast shows a PSPS Watch in Zones 2, 3, 4, 5, 6, and 8 for the upcoming event. PG&E said it is important to note that the PSPS is not executed across entire Zones and more detailed maps where PSPS is being considered will be provided on PG&E’s website Monday evening.
PG&E said this forecast is only meant to provide a high-level overview. Only a portion of a zone may experience a PSPS event.
According to PG&E, at this time, the highest probability areas for executing PSPS are the Northern Sierra Nevada foothills, the mid and higher elevations in the Sierra generally north of Yosemite (northern portion of Zone 8), the North Bay mountains near Mt. St. Helena, small pockets in the East Bay near Mt. Diablo, the Oakland Hills east of Piedmont (generally between highway 24 and Upper San Leandro Reservoir), the elevated terrain east of Milpitas around Calaveras Reservoir, as well as portions of the Santa Cruz and Big Sur mountains.
"The start of the event is more than two days away so event details will likely change as forecast models evolve. We will have more clarity on potential cities and counties impacted in the next 24 hours," said PG&E Monday.
