The CAP forecast is valid for the state of California. However, we can estimate regional precipitation forecasts by applying the statewide forecast (90-110% of normal) to the regional precipitation averages.

As a reminder, because of the NWS data gaps, we are now utilizing the Northern Sierra 8-station index data for observed precipitation totals and to compute Region 2 averages.

‍

For Region 2 (Sacramento, Yuba, Feather, and American), 90-110% of normal equates to 47.85 to 58.49”. This region gained 2.51” of precipitation since May 1. Through the end of the water year, Region 2 has received 56.55”, representing 106% of WY normal – and within the CAP forecast range.
