Record Setting

Going to go through some of the record set with our impressive January and overall start to the water year (October 1 - September 30).

The first two images show the massive amounts of precipitation that have fallen over central and northern California in January. They also highlight how dry it has been recently.

Thanks to our friends at the WRCC for creating these plots. Some areas received more rain in one week than all of 2013 (top image)!!!!!! Also there are some large swaths of areas that have already seen 40%+ of annual precipitation in the first 15 days of the calendar year!!!! These are insane stats. South Lake Tahoe also had their wettest 5, 10, 15 days all in the first 15 days of January.

When looking at the total water year, we are well above the wettest year on record (green line 1982-83). And look at the slope of the line since 1 January!!! We are nearly at the annual average and have already eclipsed 2014-15 precipitation totals.

Now, let's discuss the snow because let's be honest, that's what we care about the most. We are nearly 200% of normal for snow water equivalent and most of the higher elevations of the Sierra have 100-200" of snow on the ground right now.

As you can see there is plenty of snow to play with in the Sierra and really across most of the western US. It's been awhile since we've had a big season (2010-11), and it seems longer due to the length and severity of the drought in the Sierra since that big season.

And more good news is on the horizon. More snow is in the forecast for this week/weekend and the long range model guidance shows another wave train setting up in the Pacific. So take a minute to soak in all this good fortune and then go shred!
