PG&E says they've reduced the number of counties that could see power shutoffs in the coming days as critical fire danger weather moves into Northern and Central California.

Ahead of potentially dangerous conditions that could lead to wildfires, Pacific Gas and Electric Co. is warning of possible public safety power shutoffs affecting a small number of customers across a wide swath of Northern and Central California beginning as early as Thursday night.

Warmer winds from the Great Basin — often called Diablo winds — are now the primary concern for meteorologists as most of Northern California falls under a National Weather Service red flag warning beginning at 11 p.m. Thursday and lasting through 5 p.m. Saturday.
