HAVE A LOT OF SNOW. THAT IS THE SUM OF THE EQUATION, LET US LOOK AT WHAT WE HAVE. THIS IS ONE WAY TO LOOK AT IT, GIVES YOU A LITTLE PERSPECTIVE. WE HAVE DONE THIS BEFORE, YOU CAN SEE THE BIG DIFFERENCES FROM LAST YEAR TO THIS YEAR. THE FIRST ONE IS COVERAGE, THE SIERRA IS COVERED. A WIDE BLANKET OF SNOW COVERING THE MOUNTAINS AND HILLS. THE OTHER THING THAT IT POINTS OUT THAT IS HOW GREEN IT IS. WITH ALL THE PRECIPITATION WE HAVE HAD IN THE VALLEY AND THROUGH THE HILLS, THINGS ARE MUCH GREENER. LAST YEAR, IT WAS DRYER. WE HAVE DIFFERENT SHADES OF BROWN. THE SIERRA SNOWPACK, THAT IS HOW THEY ARE DIVIDED UP. THESE ARE THE NUMBERS WE HAVE FROM JUST YESTERDAY. AS FAR AS WATER CONTENT, WE ARE LOOKING GOOD. BETWEEN 50 AND 60 INCHES OF WATER, UP TO 283% OF AVERAGE. IMPRESSIVE NUMBERS. THESE ARE THE PERCENTAGES WE HAD LAST YEAR, ONLY ABOUT HALFWAY OF THE SEASON AVERAGE TO THIS POINT. WE ARE DOING ABUNDANTLY GREATER THEN WE WERE LAST YEAR. STATEWIDE, 222% OF THE SEASON AVERAGE AND WE STILL HAVE MORE SNOW IN THE FORECAST.

The 10 biggest weather stories of 2023 in Northern California

California is no stranger to different types of weather as the seasons change, but what made 2023 so different is that the first few months were packed with heavy storms.

Those storms and atmospheric rivers brought about rain, snow, wind, and the flooding and closures that would follow. And with all that wet weather, much of the state was taken out of what is considered "exceptional drought."

Another thing worth noting is that 2023 was another year where wildfire activity was not as extreme. There were no significant wildfires in Northern California when compared to previous years.

Unforgiving Floodwaters

When Highway 99 in Sacramento County flooded days after the new year began, it was disastrous. Several people had to be rescued after getting caught in the floodwater.

Not only was a crucial part of the highway connecting Northern California with the Central Valley blocked off, but three people had also died from the floods.

This led to criticism about whether state road officials should have shut down the highway sooner.

An overhead view of storm damage, flooding

To get a full scope of how bad flooding was this past winter required an aerial perspective.

KCRA 3 Chief Meteorologist Mark Finan joined LiveCopter 3 in January to inspect the widespread flooding damage in Sacramento County.

Unrelenting winds, toppled over trees

As the first major rainstorm of the year passed through Northern California, heavy gusts of winds followed, knocking over many trees that had loosened soil from all the rain.

That led to hundreds and thousands of utility customers in the area without power, and roadways were blocked by trees and debris.

Tracking Tropical Storm Hilary in California

Southern California saw a rare hurricane that was downgraded to a tropical storm that brought with it heavy rains and wind.

Once the storm further weakened upon reaching land, its remnants also managed to impact parts of Northern California. Residents were told that if they heard thunder to get inside.

In El Dorado County, those who lived near the Caldor Fire and Mosquito Fire burn scars were told be cautious in case of debris flow.

Replenished reservoirs

California reservoirs were looking abysmal after years of disappointing rainfall.

Once that changed after this past winter, the before and after views were hard to miss.

At Lake Oroville, the tallest dam in the country, the reservoir was at 99% capacity in June. According to the Department of Water Resources, Lake Oroville has not been this full at this point in the year since 2012.

Lake Shasta, the state's largest reservoir, was also almost fully replenished.

The year was so good for California that the state in April announced it would be able to provide 100% of the water requested by cities and farms for the first time in years.

Look at that spillway flow

Speaking of Oroville, 2023 was the second release of water at the dam's rebuilt spillway since a flooding crisis in 2017 collapsed the main spillway, eroded an emergency spillway and forced more than 180,000 people to evacuate.

The first release since the rebuilt spillway was in April 2019 to release about 25,000 cubic feet per second.

The spillway has a total capacity of 270,000 cubic feet per second, he said.

More time on the slopes this year

There's no denying the snowpack this year was much-needed and nearly historic.

Heaps and mounds of snow led many Tahoe-area ski resorts to extend their season, much to the delight of skiers and snowboarders.

Snow this late in the season was not so great

Normally, much of the snow has already long melted by the time Memorial Day rolls around. That was not the case this year, and several campsites and state parks were still closed — in the summertime.

State parks across several counties in Northern California announced partial closures, which meant the entrances were open, but select trails or campsites were closed.
