The position of a ridge of high pressure is expected to create what are known as the “Diablo winds,” which blow out of the north and east. Farther south, the winds are known as “Santa Ana winds.” Diablo winds can occur both during the spring and fall but are usually more impactful during the autumn months. California has faced growing drought conditions, with 75% of the state considered to be unusually dry and 14% officially in drought conditions.
SACRAMENTO, Calif. – The Golden State’s largest utility provider is warning thousands of residents that power shutoffs may be needed to help reduce the threat of wildfires, as Diablo winds are expected to begin on Thursday and possibly last into the early weekend.
PG&E has warned upwards of around 32,000 customers in Northern and Central California to expect shutoffs starting on Thursday, with the greatest threat on Friday.
The potential power outages are part of the Public Safety Power Shutoff program (PSPS), which is designed to reduce the risk of electrical equipment starting fires.
The FOX Forecast Center says the combination of northerly to easterly winds and low relative humidity values has caused local National Weather Service offices to issue fire weather alerts such as a Fire Weather Watch and Fire Weather Warning for millions of Californians.
“Behind today’s system, dry northerly winds will develop along the western side of the Sacramento Valley tomorrow before more widespread offshore flow develops tomorrow night through midday Saturday. The strongest winds are expected in the Sierra Nevada foothills, the western Sacramento Valley, elevated Bay Area terrain and elevated terrain in portions of the Central Coast. Winds will decrease in strength but remain offshore through Sunday, before more settled weather returns early next week,” PG&E stated in its latest advisory.
