CHEHALIS – Warmer weather, rising snow levels and a threat of heavy rain mean its time for those whose areas are prone to flooding to start monitoring the latests forecasts.
The National Weather Service says river flooding is possible this week across portions of Western Washington.
High temperatures could reach into the low 50s over the lowlands and snow levels would rise to above 6,000 feet by Tuesday, according to the weather service. Precipitation may begin late Monday and persist through at least Wednesday.
Windy conditions are possible in some areas beginning Monday night.
As of this afternoon, confidence is low as to the specific timing, magnitude and locations of the heavier rains, winds and potential flooding.
Rainfall totals of five to eight inches are possible in the Olympic Mountains during that 48-hour period, with four to seven inches possible in the Cascades, according to the NWS.
“Western Washington rivers are running low currently, but the rain will cause them to rise quickly and flooding could possibly begin Tuesday or Wednesday,” the NWS states.
People who reside in areas which traditionally flood ought to pay attention to the weather forecasts and keep an eye out for flood watches or flood warnings.
Flood watches have already been put into place in Cowlitz and Pacific counties.

Well, proof is in the pudding as they used to say. Chehalis valley is ready for a season of flooding while the lower cowlitz valley is safe due to riffe lake being eighty feet below full. Lots of ability to absorb winter storm runoff.
Inadequate drainage and reservoirs: keep building in the flood plain I guess you can expect more flooding. Just get flood insurance,… Cheapest solution to the problem. Use the money to jack up your house or just move to high ground. Chehalis is already bigger then the city planners anticipated. Bad spot for a city. Can’t fix that. Move development to a more habitable area. Once again cheaper to build a new city than figure how to stop mother natures flushing of the toilet every ten years. 500 million could build a badass city.
I said it this morning and I’ll say it again.
If you don’t get the support of the tribes, you might as well throw all that flood study money out the window driving down I-5.
We need to get them on board or you’re wasting your time.
They will always have the final say….
Maybe we could have a study conducted to see about getting a study done.
just ask DeBolt he can fix it for 480 mill
If only we had millions an millions an millions an millions of dollars to study this problem, Maybe we could study it some more.
