The Sierra Nevada snowpack is melting unusually fast this spring, failing to reach its typical peak accumulation. Historically, the snowpack hits its maximum around April 1st.
Record-breaking heat is accelerating the melt-off process. The rapid thaw is visible along the Owens River near Mammoth Lakes.
This early melt raises concerns about water availability for California, which depends on steady snowmelt runoff throughout the drier months.
