TL;DR
- The western US is experiencing a historic snow drought with record-low snowpack, impacting states like Colorado, Utah, New Mexico, and Arizona.
- This snow drought is expected to lead to significant water shortages and heightened wildfire risks in the spring and summer.
- Approximately 75% of the West's water supply relies on mountain snowpack, making its scarcity a critical issue.
- Record warmth, linked to climate change, has caused precipitation to fall as rain and accelerated the melting of remaining snow.
- The Colorado River Basin faces critical low water levels, threatening reservoirs like Lake Mead and Lake Powell, and impacting power generation.
- Reduced snowpack means less moisture in soil and vegetation, making the region more susceptible to early and intense wildfires.
- Some areas, like Nevada and Utah, are projected to receive less than half of their average seasonal water supply.
