I think it should not be raining so much for so long for four mo

I think it should not be raining for so many days. It is getting very tiring for people in Modesto California....

Love/hate rain

I agree that the rain for us here in California is at irritating levels now but thank God for the 2 inches above normal because 3 years ago I can not tell you how sad, with tears, I was when I saw the docks hanging down the side of the embankments of the lake as we were going past Mt. Shasta's area. The water levels were 15 to 20 feet from the end of the dock to the actual water line. I grew and lived in Washington state,say no more...

Tired of rain

It's getting pretty tiring for those of us in Sonoma too

RE: Rain

Stop whining. It rarely rains in the summer, and would you like the dust bowl to come back? The rains will alllow a sense of normalcy for activities in the summer. You are welcome!


Good stuff!

I would like to know what the

I would like to know what the weather will be on Thursday February 21,2019 will be in Modesto California 95351?

Green is nice, but wind turbines and solar arrays kill thousands of migrating birds, ducks and other small animals that come in contact with these wonderful contraptions. Streamers is what they call birds that are cooked when flying over the solar panels. I never see any birds when traveling on Highway 10 on my way to Phoenix. they become chopped chicken. They also have to use hydraulic fluid and oil to work. Many of them leak those oils and fluids. Green is nice, but not always good. Also where do you think the power comes from when you plug in your Tesla, yes, oil !!


People be very careful what you ask for and desire, you just might get it. Actually, we are continously being assaulted daily in various clandestine ways unbeknownst to us. We are considered "Sheeple-Not People"! However, It is still mind blowing that there are still masses of us, that are not even remotely-aware of the methods being used. "Chemtrails","Weather-Manipulation", "Weather-Modification", "Crops and Fields", (Real-Occurance!), being sprayed with lethal chemicals at night by anonymous planes and every crop dying within 3-days! How then is Organic still Organic?, aka "Silent Weapons".

December rainfall

I personally witnessed (and saw measured) a little over 3'' of rain on December 6 here in San Diego. That rain happened during a 3 hour period. That's the most rain we've had ever without having to do much research at all (ok, april 5 1926 might have been a tiny bit more). I know now more than ever its impossible to predict the weather and it's also not possible to change it. Farmers almanac predicted less than average for this month. I've been here. If you can't prove or disprove, or can't actually remember for yourself this so called "climate change" then why torture yourself that "we" are causing it? I've been her since since 89 an there has been no climate change out of ordinary. Sea level is not going up, I can see it for myself. Sure when they re-pave the street in front of your house its hot then. Plants thrive on co2 and create oxygen. Catch rainwater, plant plants, water plants. 1000 sq. ft. collects 600 gallons of water for every 1" of rain! Even in San Diego that's plenty to keep us green with no imported water. Are we all scientists or do we just want to believe those so called scientists? Lets get off our asses and stop counting on the rest of the world to do it for us!
