Tilting of the earth

Yes the big quake in Japan did in fact alter weather patterns. When the. Island moved it altered the ocean currents. Add to that the big quake in the south Pacific and currents were definitely altered. Warm water currents moved a bit north that has resulted in our weather patterns shifting north. San Francisco will begin to see San Diego type weather. San Diego will experience southern Baja Californina type weather. The conditions that create El Ninio and La Nina have been altered . look for a "NEW" norm that most of us will not like. Extended droughts, water restrictions will become a way of life.

Snow

Hi Mike,
Thank you for this great information. May I ask, what would be a good holiday vacation with snow fun for the family in the states, considering “this weather we are having now is the new normal”? Planned to spend at Yosemite National Park by looks like there is going to be no snow as of week of Christmas.

Rain in the forecast

Mike would love to know if you see any rain at all coming our way and would love to stay in touch

Your forecast

so much for forecasting the weather. its pouring in the bay area and has been for the last week.

Your prediction

Hi Mike,
I’m a Beekeeper in the CA Central Valley/mid coast area. Given your background in meteorology I’d love to get your rainfall prediction for the entire 2019 year. Would you say it’s going to be above/below normal?
Thanks!

San Diego? D

Why do they even bother selling boots coats and umbrellas here??! I hate this. Has anyone heard that we could get ANY interesting weather aside from our day in day out sunshine down here? We used to in the 90’s!

Rain South Sacramento

Will South Sacramento get any rain in the 2018 winter season? Also, will the temperatures ever decrease? It is still in the mid-eighties here.

Prospects for November rain on Catalina Island

What are the chances for a wet November for Catalina Island?

Rain wanted!!!

Hi,

I'm dying for it to rain here in the SF Bay Area. I live on the Peninsula in East Palo Alto. I just want rain, I miss it so much and everything is getting so dry. This is my first time at this website. Do you all find that the weather predictions here are accurate? Like its says it will rain in No. CA in early to mid-November. Do you think my wish will come true???

Thanks,
Susan
