Government forecasters have been heightening their warning calls for a stronger and longer El Nino.

A U.S. weather forecaster warned on Thursday the El Nino weather pattern that can cause droughts in Asia and heavy rain in the Americas will likely last into next year, longer than previously expected and potentially roiling crops and commodity prices.

The Climate Prediction Center (CPC), an agency of the National Weather Service, pegged the chances of El Nino weather conditions continuing into the Northern Hemisphere’s 2015-16 winter at 85 percent, becoming the first major forecaster to say the event is highly likely to last into next year.
