If you live in the West, you’re likely to see the words “atmospheric river” pop up in the forecast over the next several days. This is not a new term; in fact it was coined in 1994! But what is an atmospheric river, and what weather hazards can you expect? Meteorologist Haley Thiem explains.

High winds can be dangerous! If possible, stay inside. When driving, slow down, keep both hands on the wheel, and keep away from high-profile vehicles. Be aware of loose outdoor items and stay clear of trees. Visit weather.gov/wind for more information.

Debris flows often happen in areas where excessive rain causes soil to become so saturated it turns into very runny mud. The mud races downhill, picking up debris such as fallen branches, tree trunks, and rocks as it goes. Know the risks for your area: weather.gov/safety/flood-hazards Photo: FEMA
