La Nina in California this coming winter

Heard this on the news tonight. A mild La Nina.

The KNBC (Bay Area) chief meteorologist explained with a graphic that there is a 50% chance that there will be above average rainfall this year.

I'm like, whoa! 😀
 
Beyond California, I am expecting a more average winter around the midwest / lakes region based on the La Nina.

50% chance it will be higher than average... So the same chance as most years it will be higher than average? 😉

*50% chance it will be higher than the median

I'm hoping for a snowy winter as always here in MA, but no idea if this affects us.

Well, a weak Pacific La Niña can help bring more moisture to the northeast, but the devil’s in the details—get the right dip in the jet stream (to draw in moisture from the Gulf while bringing arctic air south) along with a negative NAO (North Atlantic oscillation) and you get the perfect setup for batch nor’easters pounding New England w/ multiple feet of snow (remember 1996 & 2015??)

But without the right ingredients, you could just get a warmer, rainy winter storm instead.
 
Hell, I think it already arrived in WA (just kidding). I knew it was raining pretty good after raining a lot yesterday, but I just got A flood warning until 2:10 pm message over the ERS system. Not worried where I live, but the usual Western Washington river suspects were on the announcement. Feast or famine.
 
Interesting. La Nina causes torrential rainstorms throughout winter there and causes severe flooding, natural slides, and more. It also causes vegetation to experience explosive growth. More fuel for wildfires... 🙁
 
And in the southern hemisphere on the other side of the Pacific in Australia we've got increased risk of tropical cyclones and severe flooding this summer. Might go some way to ending our drought and helping regrow some of the bushfire damage. But too much rain at once and we just end up with massive soil erosion as there's no vegetation left holding the topsoil together. To top it off, when usual service returns we'll have even more fuel to stoke the next climate induced bushfire season.
