Winter '09 / '10 - Building or Fading el Niño?

NOAA bets the farms on a building el Niño this winter while AccuWx leans the other way with its expectation of a fading +ENSO.

Despite the decidedly different expectations...their temperature and precipitation charts appear surprisingly similar.

SST measurements in ENSO Region 3.4 are currently reporting weak +ENSO conditions (12-week moving average SSTanom +0.7°C having peaked @0.9°C 16-Sep).  Anomalies have risen in Region 4 to 1.0°C as the center of action shifts toward the International Dateline.
