SoCal North

I just moved from San Diego to Eugene a few months ago, only to find the region is turning into Southern California North.

Hoq many more years of this can we take before the rivers run dry and the hydro plants fail?

This is getting really scary, such little rain!!

The Farmer's Almanac has been close most years, but this year it's the roll of the dice....Here in Brookings we usually get a lot of rain, but this year its horrible...Great weather but its not normal for this time of year, what is going to happen next spring and summer when everything is really dry?? We already had a scary 190,000 acre fire 2 years ago that came 5 miles from town, my heart goes out to all those people in Paradise CA who lost their homes and lives....Time to pray for rain folks!!

Pray for Rain

We concurr completly!!!!! We are praying every day for rain. This is very very scary..and it seems to coincide with pple moving to the pnw en mass. HORRIBLE. We are in issaquah and see heat syress on the red cedars and Tolt River drying up. Heart breaking

Low rainfall!

I'm in agreement Ron and am getting quite fearful as to what next summer will bring. This past winter was relatively dry then we went through a long, hot summer. I have ponds on my land and they aren't filling up. Usually torrential rains during late October and November would have done the job. My wife noticed no geese or ducks. I said there's little water for them to have an easy take off once landing. We usually have flocks of them coming in. We're not too far from the Ridgefield National Wildlife Refuge. The have access to the river and estuaries associated withe Columbia River, but streams and inland ponds that need rainfall are low to dry. I had to dig a grave for one of my pets. The ground was like concrete below several inches and this was in an area of rich topsoil. All we can do is hope and pray. : |

Western Washington Weather

Last year Old Farmer's Almanac stated that we would have a colder than normal winter here in the Seattle area and we didn't see any frost until near November, no snow until Christmas Eve. This year, it says we are to expect a warmer than normal winter.

If last year was colder than normal, then this year it might as well be a rainy summer. I'm hoping that the prediction is wrong and that it actually gets cold this year.

Snow in Olympia on November 3rd

It dumped last November 3rd in oly

Been dry no rain at all.

October was very dry and sunny. Same as nov forecast shows sun through mid month. It's climate change, no longer can you predict the weather accurately based on past trends. Paradise ca whole town burnt where my family is. 3 family members houses burnt. 8 percent humidity in nov. Same as here in klamath region just 3 hours away. It's time to change the way you forecast. The old ways don't work anymore sorry.

So sorry to hear about your

So sorry to hear about your families homes, John.

So accurate been reading since I was a little girl. 30 years now

I say 100% accurate even about the snow for Halloween days off snow coming down in mountain and we had hail as heavy as snow the week it said snow. Love this totally tell everyone about it.

Weather in Bend Oregon

Neither map gives a forecast for our area. We are right between the Pacific Northwest and the Intermountain Regions and neither has an accurate forecast for our area. We are located at the Eastern edge of the Cascades and the beginning of the high desert. It is kind of exasperating, trying to figure our forecast.....
