The ALMA Observatory has experienced back to back severe winter storms, making it difficult to recover the 12-m array for PI observations. This has had an even more detrimental impact on the relocation to the long baselines. Many roads are blocked with 2 meters of snow, high winds often return snow to the cleared locations, and snow is compacting into ice. We have returned to routine observations utilizing the 7-m and Total Power Arrays, and we are working hard to clear the remaining antennas to return to 12-m array PI science and reconfigure to the longest baselines. We will issue an update regarding the revised configuration schedule in the coming weeks
