Officials said there was a high risk of flooding in parts of already-saturated Northern California as the latest "atmospheric river" storm moved in. The National Weather Service on Sunday said the highest risk for flooding was in a large swath of the region from Monterey to Marin County on the coast then into the Sacramento Valley and Sierra Nevadas. The storm is expected to put added stress on...

At least two people are dead in a powerful storm that is battering central and Southern California. Flood watches and warnings are up in many places, and high winds brought down trees and power lines. The storm is part of a massive weather system coming in from the Pacific Ocean, and it could bring some of the heaviest rainfall to California in six years. Carter Evans reports.

Officials say Colorado has about 834 million standing dead trees, threatening to worsen wildfires and degrade vital water supplies that flow from forested mountains.The Colorado State Forest Service said Wednesday that the number of dead trees has risen nearly 30 percent in seven years.They are most visible in forests infested by the mountain pine beetle and the spruce beetle, which have together attacked more than 7,900 square miles in Colorado.Dead trees can burn more intensely than living ones. They can also worsen erosion, contaminating runoff from rain and melting snow.Officials say 80 percent of the state's population...
During the strong El Niño event during the winter of 2015-2016 the West Coast's shoreline eroded precipitously. In January of last year, drones captured video of houses perched perilously on rapidly-eroding cliffs along Californiaâ€™s coast. Those houses in Pacifica, California werenâ€™t alone, as waves driven by El Niño tore away huge chunks of the shoreline over the winter of 2015-2016. Now, researchers have had a chance to take stock of the damage, and found that in many places, the shoreline eroded far past the normal beating taken during winter storms. In a study published Tuesday in Nature Communications, researchers found that the shorelines eroded 76 percent more than normal, a dramatic increase. â€śTypically, we have larger waves in the winter and you lose about 20 meters of beach, then in the calmer summer and fall, the beach builds back up,â€ť Patrick Barnard says. Barnard is a coastal geologist with the United States Geological Survey (USGS) and the lead author of the Nature Communications study. He found that last winter, some beaches lost as much as 35 meters (114 feet) of sand. Long-buried bedrock and pilings from old piers reappeared as sand was swept away, exposing cliffs like the ones in Pacifica to the full fury of the waves. Along with high sea surface temperatures and other climatic factors, those waves made the El Nino event of 2015-2016 one of the largest in recent history, ranking with El Niño heavyweights of 1982-1983 and 1997-1996. In the paper, Barnard and colleagues show that this was one of the strongest events in the past 145 years. Gary Griggs (no relation to the author), is another coastal geologist who studies the erosion along the coast, and wasnâ€™t involved with the current study. Griggs is more hesitant to compare the events of 2015-2016 with events so far back in the past. Wave strength data has only been collected for about 40 years, and while early settlers in California might have enjoyed the beach, they werenâ€™t mapping it seasonally. â€śWe donâ€™t have 100 years of beach profiles,â€ť Griggs says. But, the unavailability of longer data sets notwithstanding, â€śI think theyâ€™ve done everything they can with the data available.â€ť Griggs says, agreeing that this was a very large and powerful event that affected the entire West Coast. Both Barnard and Griggs worry that the future of the beaches could be grim. â€śDuring the last very large El Niño in 1997-1998 the beaches took a decade to recover,â€ť Barnard says. After last winter, the beaches only bounced back by about 60 percent in the summer, as calmer seas pushed some of the sand that had been excavated back towards shore. Beaches also get a helping hand from the land. Sediment and sand to replenish the beaches is washed out to sea by rivers, and California's unusually wet winter this year is helping in that regard. Griggs says that flooding just a few weeks ago in some areas was powerful enough to sweep cars down onto a beach. Anything that carries SUV's can also carry sand. But recovery is a slow process. While strong storms sweep sediment towards the beach from the land, they can also bring powerful waves that eat away the coast even more. While runoff from recent storms could be a boon to the beaches, the shorelines remain vulnerable, and could get more vulnerable in the future. â€śThe science is settled,â€ť Barnard says emphatically. â€śThe climate is changing, and it's changing more rapidly. Sea levels are rising theyâ€™re rising more rapidly.â€ť â€śThe big question for us is what's going to happen when we have an El Niño event like this and a meter of sea level rise." Even without a strong El Niño event like last yearâ€™s, a meter of sea level rise could have a significant impact on coastline and people that live on the coasts around the world. â€śThere are about 150 million people living within 3 feet of high tide,â€ť Griggs says, adding that eight of the 10 largest cities in the country are located along coasts. While natural systems like mangroves or seagrasses might eventually respond to sea level rise, â€śYou can't move cites very easily,â€ť Griggs says. â€śIn some sense this is an indication of what's to come,â€ť Barnard says. â€śWith sea level rise it wouldn't take as much of an El Niño event to have this kind of impact.â€ť
