Elevation, the great outdoor gear shop in Lone Pine (make sure to say hi to Jon and Kastle when you stop in!), posted this update today:
"Onion Valley and Whitney Portal Road Info:
Inyo County Roads Department asked if we would post a reminder to our hikers, skiers, & Etc.
The roads maybe mostly snow free, but are not maintained until the official opening of fishing season, the last weekend of April. Until then, the roads are "Officially Closed."
Any travel on these roads is at your own risk; snow, ice, pot holes, rock fall & slides, and random road closures (Actually blocking the roadway) due to maintenance crews should all be expected.
Between now and the road opening, crews can be expected anytime Monday-Friday, 6:30 am - 4:30 pm with large road maintenance equipment left roadside overnight. As these crews are working to get us access to the places we play, please be conscious and considerate of them.
As always please travel safely and call us for the latest."
So, bottom line, road is closed, travel up at your own risk, and if you get a ticket, don't whine.
