What could trigger a PSPS?

High wildfire risk areas could experience a PSPS when on-the-ground factors and weather conditions create an extreme wildfire risk that could lead to loss of life, catastrophic damage, and be difficult to fight.

We look at a range of factors before considering using a PSPS for community safety:

• Dry trees, brush, and other potential wildfire fuel
• High, sustained winds
• Extremely low humidity
• Current and forecasted weather conditions from multiple third parties
• Real-time observation from on-the-ground experts
• Input from local public safety and health agencies
