I am in a somewhat similar situation… I live in SoCal, so I have access to elevation, but not snow, on a regular basis.
I suspect the best that we can do for sport-specific training is, for the uphill, box steps or uphill hiking, and a nordic track for skinning. For the downhill portion of our training, I am focusing on core and leg-strength training. I am just starting my training for the fall, and once I get into the base periods, I think focusing on eccentric exercises such as split bench squats will be my go-to for getting ready for big days in the mountains.
Hoping people more qualified than I will also chime in here!
