Despite a few large storms in January and February, California snowpack levels are near record lows due to a heat dome that settled over the state in March.

CAISO says that 8,100 MW of new resources and California's record snowpack, which is expected to increase hydro generation by 72%, improve its summer forecast.

A series of storms have started to fill depleted hydroelectric reservoirs and build deep snowpack in California while also causing power outages and flooding.

The latest forecast from the state Department of Water Resources warns Californians to prepare for a third consecutive year of drought because of low snowpack.
