California’s Snowpack Drops to Record Low of 10-20%, Sparking Early Wildfire Concerns

California’s snowpack has hit an alarming record low, raising concerns about early wildfire incidents. It is currently ranging at a new record low between 10% and 20% of normal levels, CalFire shared in a social media post. 

As the state heads into the dry season, the low level of the snowpack is more than just a water supply problem, as it plays a significant role in the state’s fire conditions, the agency reminded. 

Snowpack works as a slow-release water source. As the temperatures begin to climb, the snow begins to melt and hydrates plants and grass for prolonged periods, CalFire explained.

This delays the onset of dry conditions that wildfires thrive on. 

When the snowpack melts faster than normal, vegetation tends to dry out weeks earlier. The drier the grass and brush get, the easier it ignites, enabling fire to move rapidly through it. 

This year, the situation has been compounded by an unusually dry and warm end to winter, which accelerated the drying process. As a result, vegetation moisture levels are below normal than what is typical for this time of the year, CalFire said. 

In March 2026, the California Department of Water Resources said the state had lost nearly 20% of its snowpack since late February. This raised concerns about diminished spring runoff and an earlier melt season. 

California’s snowpack hit its seasonal peak on February 24, 2026, with the snow water content measuring 16.4 inches, which was around 61% of the April 1 average. By March 9, 2026, the snowpack had declined to nearly 50% of the April 1 average. 

CalFire Chief Joe Tyler emphasized that fire activity in California does not follow a predictable pattern.

“Conditions this year are a reminder that preparation cannot wait,” he said in a post on X.

Importance of California’s Snowpack

Snowpack is the snow that accumulates in the state’s mountains during the winter months, especially in the Sierra Nevada. The snow acts as a natural reservoir that gradually melts over spring and summer, flowing into the artificial reservoirs. 

Usually, snowpack’s depth and water content peak around April 1, according to the National Integrated Drought Information System (NIDIS). The April 1 date is, therefore, used as a primary indicator of spring runoff. 

Decreased snowpack and streamflow, combined with increased evaporative demand, dry soil, and large-scale tree deaths, often result in increased changes of large wildfires, according to NIDIS. 

In addition to wildfire hazards, the rapidly diminishing snowpack will affect key economic sectors, such as agriculture, energy production, and recreation, this spring into summer, the agency said.
