Over the next two days, many people in Northwestern Oregon, the Portland Metro area, parts of the Gorge, and portions of the Hood River Valley need to be on alert for landslides.

The National Weather Service issued a flood watch from 2 p.m. today through 4 p.m. Wednesday.

The specific areas impacted are the central and northern coast, the Coast Range, the central Willamette Valley, the greater Portland metro area, the central and western Columbia River Gorge, and the upper Hood River Valley.

The NWS warns that heavy rain can trigger landslides and debris flows in steep terrain, and that they move faster than a person can run. The risk is even higher in burn areas. Landslides can carry heavy and destructive objects like boulders and logs, and areas below steep slopes and near the mouths of canyons may present a serious risk to people, structures and roads.

If your home, work, or route is in a watch area, here are some important safety tips from the NWS:

-Stay alert. Track the flood watch by radio, TV, weather radio or online. If told to evacuate, do so immediately.

-Listen. Unusual sounds might indicate moving debris, such as trees cracking or boulders knocking together. A trickle of falling mud or debris may precede larger landslides. If you think there is danger of a landslide, leave immediately.

-Watch the water. If water in a stream or creek suddenly turns muddy or the amount of water flowing suddenly decreases or increases, this is a warning that the flow has been affected upstream. You should immediately leave the area because a debris flow may soon be coming downstream.

-Travel with extreme caution. Assume roads are not safe. Be alert when driving, especially at night. Embankments along roadsides may fail, sending rock and debris onto the road.
