That brings challenges, according to Anderson. \u201cIn the Northern Sierra Nevada, there\u2019s not a whole lot of watershed above 7,000 feet for snow to accumulate,\u201d he said, meaning \u201cthere\u2019s not much land for that snow to build up on.\u201d<\/p>\n

The potential consequences of lost snowpack put experts on edge.<\/p>\n

For starters, there\u2019s the possibility of greater fire risk. As the snowpack melts, water running down the Sierra helps keep vegetation and soils moist when the weather dries out. The ecosystem has grown to rely on that replenishment; without it, dry vegetation could become fuel for wildfires.<\/p>\n

Snowpack also refills reservoirs as it melts. Without it, we don\u2019t have that steady stream to replenish our water supplies.<\/p>\n

This year, reservoir levels are at more than 100% of their historic average overall, according to the California Department of Water Resources<\/a>. That\u2019s thanks to plenty of rain and solid snowpack from previous winters.<\/p>\n

But if a warm winter like this one follows after a few dry years, experts say a weak snowpack could force Californians to curtail water use in the summer.<\/p>\n

<\/p>\n

\u201cIn a year where we really might need it, if it\u2019s not there, that is the kind of situation where people everywhere in California are gonna notice,\u201d Swain said.<\/p>\n

Right now, the statewide snowpack is sitting at 69% of the normal for this time of year, with the Northern Sierra lagging the most, according to the Department of Water Resources<\/a>.<\/p>\n

Looking ahead, Anderson said he\u2019s hoping for a run of colder storms later this month and in March, with lower freezing elevations that can rebuild a healthier snowpack. If dry or warm stretches drag on for two weeks or longer, he warned, \u201cyou\u2019re backsliding a little bit\u201d and possibly losing ground on snowpack, he said.<\/p>\n

The current storm could help snowpack \u2014 but don\u2019t celebrate yet<\/p>\n

The storm moving through the state may bring the Sierra snowpack closer to normal. But this year\u2019s warm weather is part of a pattern that experts expect to continue, thanks to climate change.<\/p>\n

Fortunately, as Desert Research Institute climatologist Dan McEvoy points out, California is still benefitting from a few good years of snowpack.<\/p>\n

In particular, a cold, wet winter in 2023 produced a solid snowpack that put the state in strong shape heading into the current season. All of that stored water acts as a buffer, helping California ride out a year when snowpack is weaker.<\/p>\n

But experts aren\u2019t ready to say that the 2026 water outlook is worry-free.<\/p>\n

\u201cJust missing two or three [storms], not having those [cold] storms show up during the winter, can make or break a drought year,\u201d McEvoy said.\u200b<\/p>\n

As UC climate scientist Swain put it, this season\u2019s high temperatures, high freezing line and low snowpack \u201cwould be less concerning if this were just a totally aberrant anomaly.\u201d<\/p>\n

Unfortunately, he said, our changing climate means \u201cit\u2019s part of a sustained trend.\u201d<\/p>\n

So while things may be looking better after this week\u2019s storm, the bigger problem isn\u2019t going away.<\/p>\n","protected":false},"excerpt":{"rendered":"That brings challenges, according to Anderson. \u201cIn the Northern Sierra Nevada, there\u2019s not a whole lot of watershed…\n","protected":false},"author":2,"featured_media":479063,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[47],"tags":[192,79],"class_list":["post-479062","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-environment","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/479062","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=479062"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/479062\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/479063"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=479062"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=479062"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=479062"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
