People standing by river wallSTORYLINE:Rainstorms continue to pummel the Pacific Northwest in the U.S. and British Columbia in Canada this fall, causing extensive flooding and damage. A weather pattern known as an atmospheric river carries moisture from the ocean onto land. Studies indicate climate change is making the region's atmospheric rivers warmer, more frequent and more intense.The region is known for rain, but not of such sustained intensity and warmth, says National Center for Atmospheric Research climate scientist Daniel Swain. He said that is why there's been extreme flooding.Warm storms means that precipitation falls as liquid rain rather than frozen snow, particularly up in the mountains. Rather than water being "stored" in snow until it melts in the spring and summer, winter rain produces rapid runoff into rivers and streams, flooding communities. He said communities must prepare to deal with increased rainstorms and flooding in the fall and winter. "How do we how do we rebuild infrastructure or re-imagine infrastructure for a very different 21st century climate?" Swain said.___Peterson reported from Denver.
