Overview

• Extreme snowfall in California, termed as 'snow deluges', is expected to decrease by 58% by the end of the century.
• The 2023 record snowfall in California was a rare event, with such high levels of snow accumulation becoming increasingly unlikely.
• Snow deluges have both positive and negative impacts, including water supply enhancement and potential infrastructure damage.
• Climate projections show a general decline in snowfall across the Western U.S., affecting water resources and ecosystems.
• Efforts to adapt to changing snow patterns and reduce greenhouse gas emissions are crucial for mitigating future impacts.
