|SYNOPSIS FROM THE SAN DIEGO OFFICE
A Pacific storm affecting Southern California will exit the area this evening. The heaviest rain will continue to be focused along the coastal mountain slopes with very strong winds from the mountain ridge tops to portions of the deserts. Rain will come to an end this evening with cool and dry weather behind the storm this weekend with areas of brisk offshore winds. Fair and only slightly warmer next week with continued offshore flow
Very strong winds were occurring at mountain tops and could occur at anytime across portions of the desert floor should mountain waves surface. Max gusts have been 71 mph at Whitewater and 70 mph at Volcan Mountain. A few downed trees have been reported in the mountains. WRF is less aggressive on showing mountain waves surfacing in the deserts, but will keep the High Wind Warning for the deserts as it still is possible.
