The ARC Raiders Weather Monitor System was a five-stage seasonal project introduced with the Shrouded Sky update on February 24, 2026. It required 20 types of topside materials and awarded items at each stage, plus an Anemometer backpack charm and 250 Raider Tokens for completing all five. The project has expired; players who contributed but did not finish were told to check their in-game inbox for compensation.
Is the Weather Monitor System still available?
No. The project is no longer completable. In its April 14, 2026 Patch Notes 1.24.0, Embark told players who contributed to the Weather Monitor Station Project but could not complete it in time to check their in-game inbox for compensation. The official notice confirms it had ended by then; third-party project pages list March 31, 2026 as the end date, but the official notice does not specify that exact final day.
What was the project?
Shrouded Sky’s official patch notes classified the Weather Monitoring System as a seasonal player project. The February 23, 2026 announcement said Shani would task Raiders with collecting materials to build a weather monitoring system, with specific topside items contributed toward its features in exchange for rewards. The project had five stages, each with its own contribution checklist and reward bundle.

What is confirmed about dates and item details?
The official Shrouded Sky update launched February 24, 2026, and its materials identify the project as part of that update. Third-party pages disagree about the listed start date, so February 24 is the reliable launch context rather than the January 23 date shown by one guide. Detailed contribution quantities and rewards come from community/reference pages; the retrieved official notes establish the project’s purpose and seasonal status but do not provide a complete stage-by-stage item table. The sources cited here also do not establish item drop rates or verified farming routes.
