The Springs fire in Riverside county has grown to 3,500 acres, prompting local authorities to issue several evacuation orders. The fire is concentrated in an area mostly north and east of Lake Perris, burning portions of the surrounding state recreation area.

The study highlights how rapid Arctic warming increases the frequency of extreme weather events, particularly concurrent heatwaves across Europe and eastern Asia.

We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.

In late January, Toronto was hit with what many experts said was the heaviest single day of snowfall in the city's history. In some spots, nearly 23in fell, driven in part by a collision of weather systems. The city had already removed 264,000 tonnes of snow from 1,100 km (680 miles) of roads, sidewalks and bike lanes by mid-February.

The powerful March storms that drenched Hawaii produced more than 2 trillion gallons of rain and pushed precipitation levels to as much as 3,000% above normal in a 14-day period for this time of year.

"We're always glad to welcome winter back, and this latest round of snow has ensured there are still great turns to be had as our spring season continues. Late season powder days are a bonus, and with the spring events and deals we have planned, it's not too late to get up here for some great skiing and riding!" - Mike Pierce, Marketing Director, Mt. Rose Ski Tahoe

SWE is the most important metric for all of our water resources. It's the metric that we deal with the most and the one that the entirety of the snow research and operations community is working to get right. So, seeing an increase in SWE like that, even if it's from mid-winter rain, is a great thing because that means we have more water stored in the snowpack moving forward.

Showers moving into the region from the Central Coast should bring steady rain to Ventura and Los Angeles counties Thursday morning, with frosty temperatures pushing snow levels lower than normal, potentially impacting commuters along the Grapevine, according to the National Weather Service. "Steady precipitation will taper off to showers by late this afternoon and become confined to the mountains by late tonight," the weather service posted in a Thursday morning forecast.

To get back to average snowpack, we essentially need to have the most snow that we've ever had for the last 30 years between now and mid-April. It would be extremely difficult for Colorado to get back to a normal/average snowpack. As an example, when looking at the Independence Pass SNOTEL site in central Colorado outside of Aspen, we typically have 13 inches of snow-water-equivalent at the end of February. This year, we only have 6.7 inches of SWE.

"A dry January, which is historically the wettest month of the year in California, has now eroded the gains made at the start of the year and forecasts currently show no major precipitation in the next two weeks," California Department of Weather Resources spokesperson Jason Ince wrote in a Jan. 30 news release. The first month of the year certainly left the area warmer and drier than usual, weather officials confirmed.

After experiencing one of the wettest holiday seasons on record, still soggy California hit a major milestone this week - having zero areas of abnormal dryness for the first time in 25 years. This data, collected by the U.S. Drought Monitor, is a welcome nugget of news for Golden State residents, who in the last 15 years alone have lived through two of the worst droughts on record, the worst wildfire seasons on record and the most destructive wildfires ever.

Last week alone, parts of western Switzerland were buried under 1 to 1.5 meters (3 to 5 feet) of snow. Another meter fell this week in some regions, pushing fresh storm totals to as much as 2.5 meters (8 feet). The new snow has helped erase what had been a snow-poor winter in the west, with snow depths in some areas now well above seasonal averages.
