Get ready, California! A powerful atmospheric river is on its way, packing a punch that could lead to dangerous flooding. This isn't your average rainstorm; it's expected to dump a whopping 12 to 16 inches of rain in some areas. This isn't a new thing; earlier this week, a bomb cyclone brought similar conditions to the Pacific Northwest, causing chaos in Washington, Oregon, California, and even parts of Canada.

An atmospheric river is essentially a long, narrow corridor of moist air, often dubbed the "river in the sky. " It's moving slowly over northern California, and the National Weather Service (NWS) predicts it'll keep pouring down more rain—between 6 to 12 inches—on areas that are already soaked. The worst is expected on Friday, with heavy rain and lower snow levels hanging around on Saturday.

The NWS is warning about serious flooding, rockslides, and debris flows, especially along the northern California coast. They've issued a High Risk alert for excessive rainfall. So, if you're traveling, be smart and check the conditions first. Never attempt to drive through flooded roads.

Flood watches are active in Northwest California, with potential flooding in poor drainage areas and urban spots. Even creeks and rivers could overflow with more heavy rain.

You might have seen photos of flooded roads in Santa Rosa. Those images are a stark reminder of what's to come. The bomb cyclone that hit earlier this week already took two lives—one in Washington when a tree fell on a homeless encampment, and another near Seattle when a tree crushed a home.

Power outages are another issue. As of Friday, around 343, 000 homes in Washington and 16, 000 in California were without power.

So, what's an atmospheric river? Think of it as a massive transport system moving water vapor from tropical regions to other parts of the world. When it hits land, it can either dump heavy rain or snow, depending on the temperature.
