Snow-covered area for the western United States hit another record for April, the second month in a row since the satellite record began in 2001. With longer days, more sun, and increasing temperatures in the coming months, concerns arise for how quickly the snowpack may melt in California with potential for flood risks.

Algae that commonly grow on snow in the Pacific Northwest have been ignored in melt models, but their presence significantly increases snowmelt compared with clean, white snow, according to a first-of-its-kind scientific research study conducted on Mt. Baker in the North Cascades, Washington.

Extensive snow cover in the western United States continued in March 2023, surpassing the 2019 record high by 11 percent and doubling last year's average and the 23-year-satellite record average for snow-covered area for March.

In 2006, NSIDC and Argentine researchers landed on two icebergs calved off the Antarctic Peninsula and installed a battery of science instruments on each. NSIDC then tracked the movement of these icebergs as they drifted northward into warmer waters and broke apart.

Arctic sea ice has likely reached its maximum extent for the year, at 14.62 million square kilometers (5.64 million square miles) on March 6, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2023 maximum is the fifth lowest in the 45-year satellite record.

Continuing the trend of recent months, the western United States received significant snowfall in February 2023, helping to improve drought conditions in the West. Despite dominance of a La Niña conditions, current snowpack patterns resemble those characteristic of El Niño years.
