SAN FRANCISCO (AP) — A potent atmospheric river is barreling toward Northern California, bringing the threat of downpours that could unleash destructive debris flows from wildfire burn scars and a heavy dump of snow in the Sierra.
Evacuation orders are in effect for areas of fire-scarred Santa Cruz and San Mateo counties.
The atmospheric river is expected to intensify by Tuesday evening, hitting the North Bay first, then spreading south to Santa Cruz.
