Dear WeatherCat climate observers,
Those folks at the Climate Predication Center and and the International Research Institute for Climate and Society have made if official. We are now under a La Ni?a Advisory:
http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtmlThe summary reads:
"La Ni?a conditions are predicted to continue (~65-75% chance) at least through the Northern Hemisphere winter 2017-18. "The key points of discussion can be summarized as follows:
" During October, weak La Ni?a conditions emerged as reflected by below-average sea surface temperatures (SSTs) across most of the central and eastern equatorial Pacific Ocean.
. . . .
For the remainder of the Northern Hemisphere fall and winter 2017-18, a weak La Ni?a is favored in the model averages of the IRI/CPC plume [Fig. 6] and also in the North American Multi-Model Ensemble (NMME) [Fig. 7]. The consensus of forecasters is for the event to continue through approximately February-April 2018. In summary, La Ni?a conditions are predicted to continue (~65-75% chance) at least through the Northern Hemisphere winter (click CPC/IRI consensus forecast for the chance of each outcome for each 3-month period). "So for all of you affected by La Ni?a events, the next question is to figure out exactly what do La Ni?a event actually does to your location. There was a time when La Ni?as caused drought in the Western United States. However, between the fact that last year as also a La Ni?a and the current forecast for the rest of November, I decided to clean the storm drains this afternoon. Alas, of course they needed more cleaning than I had hoped.
When it comes to home maintenance, the work is never done . . . .
Oh well, . . . . . Edouard
