Driving through the huge puddles can be dangerous and hard on some cars, too. Some of the minivans have problems with the drive belt. If you go through a large puddle of snow or ice it can knock the drive belt off, explained Steve Lund Du with Fresne's Auto Repair.

The combination of heavy rain and snowmelt will make conditions perfect for potential landslides, especially in drainage areas.

The ones we're really concerned about are the ones in Southeast Portland out in the Clackamas River drainage area and Oregon City. Those are a lot of really old landslides and they reactivate if they get a lot of water. Once they start moving, it's hard to stop them and those are the ones you don't want to have happen, explained PSUGeology Professor Scott Burns.

Dangerous surges in rivers and creeks can also develop in these conditions. Steep slopes, canyons, gorges and the mouths of mountain streams were the locations at greatest risk for debris flows of logs, soil and boulders, experts said.

Officials warned not to stand too close to the edge of steep slopes and pay attention to sounds that may precede a slide, if you re near rivers or canyons. Also, driving through flooded areas is unsafe, since there may be unseen damage to the roadway.

If water in a river or stream suddenly turns muddy or the amount of water suddenly decreases or increases, the flow has been affected upstream and a debris flow may soon be coming downstream, experts said.

Cleaning up immediately after landslides can also be hazardous, since a small mudslide can actually be part of a larger landslide.

One of the worst years for landslides in the Portland Metro area was back in 1996. About half of those slides occurred in the West Hills.

More recently, a mudslide almost took out a home on Portland s east side. If that happens, insurance will not cover the costs, unless the homeowner has specific landslide insurance.
