Mt Whitney Zone Forums General Discussion Help with Mt. Whitney conditions in April.

I might get a chance to get to Whitney in April of next year and I'm trying to get some beta of how the routes will be. I'm looking at the main Whitney Trail not the Mountaineers Route. How well is this trail marked? Is it easy to lose the trail? I haven't found many trail reports for April attempts. What can I expect as far as trail conditions? This would most likely be a solo day hike attempt.
