Mammoth Mountain Long Range Discussion

1-28-23 – Taking a look at the long range outlook, Mammoth Mountain is back in the drier La Nina pattern that we saw last season. Do look for some snow over the next few weeks, but the overall consensus is to expect well below normal snowfall during February.

The La Nina is weakening fast now and if that keeps up there could be some decent snow in March and April.

Overall the Mammoth area is around 135% of average for the entire snow season, so even of there are some drier times the mountain will still be wel above normal for the season.

Pray for Snow, Snowman
