Mount Rainier Recreational Forecast
National Weather Service Seattle WA
337 PM PDT Mon May 11 2026

.SYNOPSIS...A ridge of high pressure will produce a warming
trend through Tuesday. A transition to onshore flow and cooler
temperatures will take place Tuesday night into Wednesday along
with a chance of some precipitation. Expect strong winds near the
summit. Cooler and unsettled conditions are expected into the
weekend as a trough of low pressure over the Northeast Pacific
sends a series of weak frontal systems across the area.

&&

.IMPACTS...Strong winds near the summit will make it difficult to
move safely and could produce local whiteout conditions. A high
level of skill and experience in alpine terrain, including use of
GPS, is recommended for navigation and camping in these
conditions.
