It takes more components than warm ocean surface temps to make an El Niño "wet".
97-98 was near normal in temps and rainfall on the coast of Michoacan, and I came north twice during the winter to Tucson. I read about the flooding in California.
The JET STREAM must collaborate to bring moisture. And steering mechanisms are influenced by high and low pressure regions and movements. This is what steers the jet stream.
For a soaked California, the SOUTHERN jet stream must migrate northward. A Pineapple Express must form and continue. When pulses stretch from the Philippines to North America via the jet stream then lots of moisture can take place.
A mere ENSO event is one component. Anyone who tries to extrapolate an ENSO event into hard and fast specific region rainfall predictions is either a fraud or a fool. A jet stream ENSO event can be a mere two to three hundred miles wide at the extreme.
Yes, I have a minor in meteorology. It protects me against being gullible for news-worthy buzz words. Like EL NINO
Here is an excerpt from a USA TODAY article (verbatim)
Extreme weather and natural disasters account for quadruple as much television network news airtime as they did during 1990s, yet this actually deters viewers from taking precautions and actions. People reportedly find the inundation of information overwhelming, and therefore preventative actions are thought futile.
The idea that too much sizzle is being served up to viewers along with too little substance has been framed as "weather porn." Sure, disaster sights are provocative, but they can also serve to inform. This is where weather news largely falls down. Sights are left for viewers to see and reports for viewers to hear. What about what viewers can do?
