The road conditions web page from Inyo N.F. is here:

It shows Horseshoe Meadows road still closed, but their update date is Apr 24. Note they also give the Inyo County road dept phone number, so you could call them and find out.

From the web cam views, the storm does not appear to have dropped any snow on the east side, so I would expect the road to open up very soon.
