el ninno, long term rain predictions

verichip - 7-3-2019 at 01:49 PM

Is it going to be a wet winter?
I got rained on today, I got rained on yesterday, I got rained on all last week.

Will Baja be getting lots of rain this winter?

ENSO Alert System Status: El Niño Advisory

Synopsis: El Niño is predicted to persist through the Northern Hemisphere summer 2019 (66% chance), with lower odds of continuing through the fall and winter (50-55% chance).

During May, El Niño was reflected in the continued presence of above-average sea surface temperatures (SSTs) across most of the equatorial Pacific Ocean [Fig. 1]. The latest weekly ENSO indices indicate the largest positive SST anomalies were within the central Pacific (+1.1°C in Niño-4 and +0.9°C in Niño-3.4) with smaller departures in the Niño-3 and Niño-1+2 regions [Fig. 2]. Upper-ocean subsurface temperatures (averaged across 180°-100°W) were nearly average at the start of May, but positive anomalies increased toward the end of the month in association with a downwelling Kelvin wave [Fig. 3]. Thus, anomalies remained positive at depth in the central equatorial Pacific Ocean, with negative anomalies evident in the eastern Pacific [Fig. 4]. Suppressed tropical convection continued over Indonesia, while weak, enhanced convection persisted near the Date Line [Fig. 5]. Low-level wind anomalies were westerly over the western tropical Pacific Ocean, and upper-level wind anomalies were easterly over the western and east-central Pacific. Overall, oceanic and atmospheric conditions were consistent with El Niño.

The combined averages in the IRI/CPC plume predict El Niño to continue into Northern Hemisphere winter 2019-20, but individual models span ENSO-neutral to El Niño outcomes (generally +0.0°C to +1.0°C; [Fig. 6]). The forecast consensus reflects this uncertainty, with slightly lower chances for El Niño compared to the previous month. Ongoing subseasonal variability within the tropical Pacific contributes to an overall murky picture, but the current downwelling oceanic Kelvin wave should fuel the persistence of El Niño at least in the short-term. In summary, El Niño is predicted to persist through the Northern Hemisphere summer 2019 (66% chance), with lower odds of continuing through the fall and winter (50-55% chance; click CPC/IRI consensus forecast for the chance of each outcome for each 3-month period).

This discussion is a consolidated effort of the National Oceanic and Atmospheric Administration (NOAA), NOAA's National Weather Service, and their funded institutions. Oceanic and atmospheric conditions are updated weekly on the Climate Prediction Center web site (El Niño/La Niña Current Conditions and Expert Discussions). Forecasts are also updated monthly in the Forecast Forum of CPCs Climate Diagnostics Bulletin. Additional perspectives and analysis are also available in an ENSO blog. The next ENSO Diagnostics Discussion is scheduled for 11 July 2019.

They are also predicting a 70% chance of an above normal hurricane season in the eastern pacific.
The El Nino's effect of reducing upper level wind shear and elevated sea surface temperatures give stronger, longer lasting and and more frequent hurricanes a greater chance on occurring.

A couple yrs. back, there was general conscience across
the board, due to 'warm water bubble' in the Pacific
that guaranteed an extremely wet winter here in So. Cal. Result,
not Jack.
Last winter with not a word, 185% of normal snowfall in
the Sierra, predictions?

I see barbra is already out there.
