\n\t\t\t\t\t\tThe Northern Lights could return to Northern California on Monday.

The geomagnetic activity is also forecast to be at a KP 8 level out of a range of 0-9.

SWPC Video Update from Shawn Dahl, SWPC Service Coordinator about the severe G4 and S4 ongoing storms. Apologies for the hastiness of this, but we have been very busy notifying aviation, power grid, FEMA, and more about these storms.
