here is the report from 24 Jan:

Mount Rainier National Park (WA)
Search Continues For Overdue Parties On Mount Rainier

The search for four people in two parties continues on Mount Rainier. On Sunday, a small improvement in the week's severe weather allowed ground teams to conduct visual searches of terrain previously obscured by weather. A US Army Reserve Chinook attempted to join the effort but had to turn back due to limited visibility. The helicopter remains on standby at Joint Base Lewis McChord. No sign of the missing parties has been detected to date. Over the last week, ground teams have encountered 30 to 60+ mph winds, whiteout conditions, ice crusted snow, and snow depths from 10 to 15 feet with drifts up to 50 feet. The two teams were due back on January 15th and 16th. The search effort will continue today, depending on weather and avalanche conditions. In the event a weather window materializes, the Chinook and a Washington State Patrol airplane are prepared to respond. The weather forecast calls for snow, 5 to 10 degree temperatures, and winds up to 65 mph through today. The Western Incident Management Team (Denny Ziemann IC) is managing to the incident. Mount Rainier and Denali climbing rangers, personnel from Pacific West, Intermountain and Alaska Regions, guides from Rainier Mountaineering Incorporated and International Mountain Guides, and Olympic, Tacoma, Everett and Seattle Mountain Rescue are contributing to search operations.

I will look for the initial report.
