So, still some snow falling on the upper elevations, but the valley is seeing heavy rain about now.
And it looks like fresh snow is falling on the Tioga Pass Road from Lee Vining all the way to Aspen Valley.

This is something I didn't expect -- that the water flow level would already be decreasing on the Merced River.Quote:

It is raining again in the valley and so the stream level is climbing again!

I really thought the flows would get higher. But maybe not.

Lots of snow falling on the high ground, up to 8 feet of new accumulation at 9000 feet with winds hitting 75mph ! I think the Plow crews are going to have their work cut out this Spring. Not just clearing snow, but also debris from fallen trees and rock slides !

That is a spectacular image and it's worth checking out the Yosemite falls webcam on a full screen for the impact! I have stood at the bottom of those Falls when just a trickle, to be there now would be absolutely amazing ! For those that haven't visited the Falls, the overall drop is 2425 feet and during it's peak flow, a staggering 2,400 gallons per second can flow over the lip of the upper fall !! Can you imagine?!?

Look at it this morning with the frazil ice on the side and the blue sky!

Yosemite NP opened up ' minimal' access to the Valley on Saturday after a great effort to plow pathed footpaths and restore limited services. The only access into the valley is via Highway 140.
Conditions are described as 'Very snowy' with advise to wear waterproof boots and traction devices because of ice on plowed pathways. Hiking on snow covered trails is not recommended.
Check before travelling if you are planning to visit as there is a lot more snow to come through Tuesday and into Wednesday and a Winter storm watch alert has been issued.
