Bottom Line
Good window Tuesday and Wednesday, but a storm moves in Thursday night with 96% precip chance and rain/snow — plan your exit to be off exposed terrain and back at the trailhead by Thursday afternoon. Daylight is tight at 10 hours, so early starts are non-negotiable.

Full Briefing
The storm timing is your planning anchor for this trip. Tuesday and Wednesday look clean — sunny to partly sunny, highs 46–51°F at valley elevations, light SSE winds under 15 mph. That's a solid two-day window for the traverse. Thursday night is where it falls apart: 96% precip, winds jumping to 23 mph SSS, and rain/snow. Friday adds a 100% precip chance with a slight chance of thunderstorms. If you're not out by Thursday afternoon, you're camping in a wet, potentially snowy mess with no good exit options.
Snowpack is a non-issue right now. Annie Springs at 6,021 ft is showing 0 inches of depth and 0.1 inch SWE — the high country is dry. You may hit some frozen ground or rime ice on shaded north-facing slopes at elevation in the mornings given overnight lows dropping to 35–36°F, but no significant snow travel. The incoming storm could drop snow at higher elevations Thursday night, so if you're camping above 6,000 ft on night three, have a plan for a potentially snowy pack-out Friday.
Stream crossing data is tricky here — the USGS gauges feeding this briefing are geographically offset from the Trinity Alps (Salinas River, Llagas Creek, Alameda Creek watersheds), so treat those numbers as background context only, not direct Trinity River basin data. That said, with zero snowpack and no recent significant rain, Trinity Alps streams should be at or near seasonal lows right now — early November before the first real storm. Crossings should be straightforward through Wednesday. The incoming Thursday night storm will start raising flows, but you'll be exiting before that's a factor if you stick to the schedule.
Daylight is the quiet constraint. Sunset hits at 4:57 PM, so you've got roughly 10 hours of usable light. Plan your camp-to-camp legs to finish by 4 PM — that means boots on trail by 7 AM at the latest. The south-facing aspects will warm fast on Tuesday and Wednesday with full sun, so enjoy it, but set your alarms. On exit day Thursday, start early regardless of how you feel — you want to be moving before the weather deteriorates in the afternoon.

About This Route
The Trinity Alps in far northern California are one of the state's best-kept backpacking secrets. This traverse through the Trinity Alps Wilderness passes through granite peaks, alpine lakes, and dense old-growth forests with a fraction of the crowds found in the Sierra Nevada. The route connects several trail systems to create a north-south traverse through the heart of the wilderness, passing pristine lakes including Caribou, Emerald, and Sapphire. The terrain has an alpine character similar to the Swiss Alps at a fraction of the elevation, with green meadows, glacier-carved cirques, and rushing streams. The Trinity Alps see far less traffic than comparable California wilderness areas. Permits are free and self-issued at trailheads. Black bears are present—hang food or use canisters. Water quality is excellent from the many streams and lakes. The area is hot in midsummer; consider September for cooler temps and fall color.
