Bottom Line
Great window for a Trinity Alps traverse. Weather is clean Fri–Sun with thunderstorm potential today only. Stream flow data isn't from Trinity drainages specifically, but 31 inches of snowpack at elevation means some crossings will be running — plan accordingly. Go.

Full Briefing
The weather setup is excellent for this trip. Today you've got a 23% chance of afternoon showers and thunderstorms — typical late May pattern in the Trinities. Get moving by noon and be below exposed ridgelines before 2 PM. After that, Saturday through Sunday are clean: sunny both days, highs around 62°F, winds light out of the SE at 2–16 mph, and precip probability drops to 3–6%. You've got 14+ hours of daylight and a wide-open weather window for your last two days on route.
The 31 inches of snowpack depth on record is worth taking seriously even though it's May. That's a meaningful amount of snow still sitting at elevation in the Trinities this late in the season. Stream crossings fed by snowmelt — particularly north-facing drainages above 6,000 ft — will be running hard by early afternoon after warm days. The flow gauges in the raw data are from Central Coast and Salinas Valley drainages, not Trinity watersheds, so treat them as irrelevant to your specific route. Expect crossings to be at their lowest in the morning before solar warming kicks in. If you have a big crossing on the agenda, time it before 10 AM. Poles and unbuckled hip belt are the standard moves here.
No active fires within 50 miles and no avalanche terrain concerns for a backpacking trip at this time of year. Those aren't factors this weekend.
Logistics: start early today to get ahead of the afternoon convection window. Once you're in camp tonight, you're set up for two bluebird days. With sunset at 8:29 PM you have flexibility on afternoon mileage, but the snow underfoot will soften significantly on sun-exposed slopes by midday — if you're crossing any lingering snowfields, morning travel is firmer and safer. Night temps in the upper 40s mean no hard overnight freeze, so don't count on a supportive morning crust by Sunday.

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.
