# Models Agree on Brief La Nina

> DTN reports that US and Australian forecast models agree the Pacific is in a brief, weak La Niña, with equatorial sea temperatures 1-2 C below normal and the 30-day Southern Oscillation Index at a La Niña-level reading. Both the CPC and Australian Bureau of Meteorology expect a return to neutral conditions in the first quarter of 2018.

## Why it matters

A short-lived, weak La Niña limits the likelihood of prolonged drought in key growing areas, which reduces the weather premium in grain and oilseed prices. The expected quick return to neutral conditions argues against a sustained supply shock.
