SAN FRANCISCO (Reuters) – California is coming off of its warmest winter on record, aggravating an enduring drought in the most populous U.S. state, federal weather scientists said Monday.

The state had a average temperature of 48 Fahrenheit (9 Celsius) for December, January and February, an increase from 47.2 F in 1980-81, the last hottest winter, and more than 4 degrees hotter than the 20th-century average in California, the National Oceanic and Atmospheric Administration (NOAA) said in a statement.

Warmer winters could make the already parched state even drier by making it less likely for snow to accumulate in the Sierra Nevada Mountains, NOAA spokesman Brady Phillips said. That snow, melting in the spring and summer and running down through the state’s rivers, is vital for providing water in the summer, when the state typically experiences little rain.

“Winter is when states like California amass their main water budget, when snowpack is building,” said Phillips, a marine biologist. “If you’re starting from a deficit and going into the dry season, it’s setting you up for a drier summer.”
