National Weather Service Seattle WA
430 AM PDT Tue Sep 29 2026

.SYNOPSIS...
Gusty winds, rain, and snow will develop across Mount Rainier
National Park today as a weather system moves across Western
Washington. Building high pressure later this week brings warmer
and drier conditions, with a more notable warm up during the
weekend.

.IMPACTS...Strong winds in alpine regions on the mountain this
week, including the Muir snowfield through Tuesday night, 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.

and snow likely in the late morning and early afternoon. Rain and
