The episode as NWS SGX wrote it up.
Strong downslope winds and mountain wave activity caused a palm tree to fall on a home in Indian Wells, damaging the kitchen and dining room. Power was knocked out to 79,000 customers in the valley. A peak wind gust of 53 mph was measured by the Thermal ASOS and a 48 mph wind gust was measured by the Palm Springs ASOS. It is likely that High Wind occurred in some of the more unpopulated areas of the Coachella Valley, especially considering how widespread the reports were of wind gusts in excess of 40 mph and that a 60 mph wind gust was measured to the north at Burns Canyon.
