TGR Community IntelStorm Day Strategy
During major storms: Mountain will close for avalanche control operations; expect 1-2+ day closures during significant precipitation events. Road closures on Highway 395 common during 'military snow' conditions. If driving from north (Tahoe region), expect 395 closure - stay in region or wait for late morning opening. Avoid expecting quick opening - avalanche control on complex terrain like Lincoln requires extensive coordinated work. Bring beacon, probe, and shovel if skiing off-piste; resorts have FOMO-driven guests with insufficient avalanche awareness. Respect patrol closures and terrain restrictions - they are managing life-threatening conditions.
Terrain Opening Patterns
Top of Mountain
Opens: Variable - weather dependent
Chapter 5 and Cornice are best skiing off top. Afternoon wind buff develops later in day post-storm
Canyon Lodge Area
Opens: Full opening typically early
Haven't the Foggiest perfect for carving around 11:30am, south-facing slopes soft by afternoon
Powder Stashes
Chapter 5

Post-storm best bet, untracked lines available late day
