No news yet that I could find
Temperatures have been slightly cooler compared to recent temperatures, but the weather is heating up this week. There may be some water left here and there in the Park from recent rains, but that will probably not last too long.
This trail is pretty easy to walk and follow. I walked it a few years ago. I think there may have been one spot where there was a tricky switchback with a deceptive wash, but overall, easy to follow. Terrain gets really rough past the oasis itself so I'd think it unlikely someone would continue too far past the oasis by accident, but if they do, they can easily get into difficulties in the boulder fields there.
There's also some good views to be had from the vicinity of the trail as I recall, so the temptation to leave the trail may be present. Even in a case like that though, based on my recollection of the terrain, you wouldn't get into too much trouble before it becomes obvious that you are astray.
The official JTNP Facebook page has a photo of SAR members heading out in the terrain where the trail is visible in the lower right of the picture. It is a pretty obvious trail.
