Weather is inherently unpredictable; Sacramento, CA (where I live) has already had more rainfall since December 1 than all of last year. El Nino events are even less predictable than "average" weather is. Meteorologists are only beginning to understand the underlying patterns of an El Nino. Is this going to be an El Nino year? I wouldn't place bets either way. The Japanese have a word, "modoki", which means "the same, only different". At least one prediction is for an "El Nino Modoki".
The NASA report today (based on data collected earlier in the year) says that California would need 11 TRILLION gallons of rain to make up for the drought. Entirely coincidentally, there was a bit (on the generally-unreliable TV news weather) yesterday that said that this year's rainstorms dropped 10 trillion gallons on the state so far this month. Not all in the right places, of course; parts of Napa County were getting an inch an hour, which is nearly Philippines style rain. The ski resorts in the mountains are rejoicing in a couple of FEET of new snow.
