Better forecasting would help communities prepare for the extreme weather that causes an average of $1 billion in damages a year on the West Coast.

New England was still recovering Friday from a bout of extreme weather that dumped rainfall across the region and left tens of thousands of residents without power.

The midweek storm, fueled by a weather system known as an atmospheric river, produced wind gusts up to 60 miles per hour and likely gave Providence, Rhode Island, its wettest winter day on record — with as much as 5 inches of rain, according to preliminary reports.

Atmospheric rivers aren’t new to meteorologists, but they are notoriously difficult to predict.
