Alert Details

A quick-moving, yet potent low pressure system is expected to continue to push east across the northern Great Lakes and into Canada tonight into tomorrow. A cold front trails southwest of the low pressure into the corn-growing region, and this front will also push east and southeast over the next 24 hours. Ahead of the front, a corridor of focused gusty south to southwest winds is present, and this may result in some isolated black cutworm moth flights north into especially the southern Great Lakes region overnight tonight into tomorrow. Low risks are in place from eastern Iowa and southeast Minnesota east as far as southern Ontario, Canada and Ohio during this time. Little to no migration risk is predicted after tomorrow, but growers all across the corn-growing region, especially those with newly-emerged corn, are encouraged to continue scouting efforts as the numerous moth flights that occurred earlier this spring are now producing larvae in some areas that are at a feeding/cutting growth phase.
