.Near-record precipitation is possible this week as two Atmospheric

continues through Tuesday, followed by a second, stronger one
Tuesday night through Thursday. Between 4 and 10 inches of moderate
to heavy rain are expected in the mountains. For some locations,
near record rainfall amounts are possible. The rain, falling on the
current snowpack, combined with mild nighttime temperatures will
increase snowmelt. Flows in rivers may increase quickly and reach
critical levels.
