If the same Pineapple Express hit last April we would have lost Oroville. A late season rain that melts the Sierra snowpack is a JH moment. Oroville is probably going over the spillway this week , ready or not.
Here in SB county we are only at ~ 50% of average rainfall. Last year we had average precipitation but we are still stuck in a very long drought. This weeks atmospheric river is forecast to miss us although the half inch of rain forecast is better than nothing. Our reservior ( Cachuma ) is at 40%.
