  1. Hi Richard. I have tried to subscribe to your blog and it tells me that I’m already subscribed but I am not receiving anything from you. I’ve checked my spam folder but nothing is appearing there either. Any ideas?

    Also, I’m wondering if you could give me any idea of how El Nino will be affecting Baja California this January? My family is contemplating a trip there in early January and I’m worried about the possibility of heavy rains. I’ve searched for weather models on-line but haven’t been able to find something for that area.
    Thanks much!

    • Hi Susan, I am not sure how to subscribe to my blog,,,,are you wanting notifications. I just assumed people will do what I do which is to bookmark the site and look at it whenever you want. As for January weather in Baja, it would be impossible to get a forecast that far out in time and it is still to early to use El Nino or La Nina to help you as we are not sure which will be true at this point. Generally, Baja weather is similar to San Diego weather which is impacted by the jet stream over California. If you want dependable weather in Mexico in Janary, go further south into Mexico like Puerto Villarta or Cancun and the Yukatan Peninsula where the northern jet stream has not effect. PV is a great city.

    • Thanks for your comment. Where are you located? This coming week will be quite interesting for the Bay Area as the jet stream will be aimed at Central California and the Sierras which could add quite a bit of snow pack that is much needed to completely end our drought. The idea of notifications is an interesting idea, but I often revise the forecast several times per day. You may not be interested in minor forecast changes.
