Climate Signals summary: Climate change is supercharging high precipitation events around the globe. Most recently, parts of Alaska endured a powerful storm that dumped record amounts of snow and rain - measured in feet as the remnants of an atmospheric river pumped tropical moisture into the region.
A powerful, historic storm has walloped southern Alaska for days, unloading extreme amounts of precipitation and overwhelming its infrastructure in some areas.
The deluge, intensified by climate change, has flooded communities south of Anchorage and transformed trickling waterways into raging rivers. Excessive amounts of snow, measured in feet, have buried the high terrain, and the long-lasting storm won’t fully relent until Wednesday.
The historic rainfall generated by the storm, includes one of the top four heaviest two-day amounts ever observed in the state, nearly 20 inches.
A fire hose of tropical moisture, the remnants of an atmospheric river, instigated the storm system, which will lash California and the Pacific Coast in the days ahead.
