We also have a email listserver that will notify folks when the ENSO status/forecast is updated once a month.  You can subscribe to it by sending an email to:  ncep.list.enso-update@noaa.gov

It will include a link to the official NOAA ENSO discussion:  

https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtml

And in this discussion is a link to the ENSO blog, which us usually updated a couple hours after the official discussion.
