The Pacific Northwest should brace for more storms, rains and snowfall this week, as a frontal system will bring moisture inland up to the Northern Rockies from Monday night throughout Tuesday. The storms may be especially dangerous for the hard-hit areas that suffered heavy flooding last week.

Residents are advised to carefully watch out for the second round of storms, which will bring heavy rain, increasing the risk of flooding and mudslides in the region. The storms can also cause road closures and urban flooding.

The affected areas in the US will include Idaho, western Montana, most of Oregon, Washington, and northwestern Wyoming states.
