Alert Details

A cold front is likely to sweep through much of the corn-growing region over the next 24 hours, and remnants of Hurricane Laura should move through the Ohio and Tennessee River valleys well to the southeast. Northwest flow behind these two systems results in little to no migration risk for much of the weekend and into early next week. It does appear, however, that another cold front should enter the western and northern corn-growing regions early-mid next week, and Low migration risks associated with a corridor of southerly wind flow ahead of this front is in the forecast mainly between I-35 and I-75 next Tuesday night into Wednesday. The threat of damage to field corn has largely passed now, but fresh market and processing growers are encouraged to continue to monitor traps and scout fields until harvest as recent flights has increased moth and larvae pressure especially in the northern corn-growing region where these growers are primarily concentrated, and new flights will still be possible in the latter portion of the growing season when weather conditions are favorable.
