NOAA's Climate Prediction Centre has upgraded the current El Niño to Super El Niño status after Niño 3.4 sea surface temperatures stayed about 2°C above average for three consecutive months. The pattern is expected to bring heavier rain and possible flooding to California and the Southwest, and milder, drier winter conditions to the Midwest and Northeast.
A strong El Niño raises the risk of weather shocks across major crop and livestock regions, which can affect US winter conditions, feed grain supply and prices. Forecasts remain variable by location, so the market impact is uncertain.
After 449 past neutral weather events, Corn moved a median +0.1% over 5 sessions (53% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
