The U.S. attache in Mexico has raises its estimate of the country's 2012-13 corn estimate to 21 MMT due to higher-than-expected harvested area are relatively favorable weather conditions. The attache also says the media overestimated damage from a mid-January freeze event.
"The expectation for the current 2012-13 fall/winter season is optimistic as they expect it will reach approximately 4.8 MMT," says the attache. "Although media outlets have highlighted a cold front and a winter storm affected large areas of Sinaloa’s corn in mid-January 2013, official sources have stated that preliminary estimates show that the impact was not more than 35,000 hectares (roughly 10% of total corn planted area) of which only partial damage actually occurred. It is important to note that Sinaloa farmers planted 371,000 hectares of corn in the 2012-13 fall/winter crop cycle."
