How could the atmospheric river system affect the Los Angeles Department of Water and Power?
Atmospheric river system may increase operational costs for LADWP The atmospheric river system funneled subtropical moisture across Southern California, driving coastal rain and high surf into coastal counties, including those near Los Angeles. The short bursts of heavy precipitation added to multi-day storm totals, resulting in minor urban flooding in coastal areas. This combination of heavy rain and flooding could stress or damage the utility's infrastructure, leading to increased operational repair costs and maintenance needs for the Los Angeles Department of Water and Power.
