Alert Details

Predominantly northwest to southeast flow is predicted to continue for the balance of the next five to seven days. As a result, corn earworm migration risks are predicted to remain in the Low category for the next several days. Low risks are predicted tonight into Friday morning from eastern Kansas into Missouri, southern Illinois, southern Indiana, and western Kentucky as short distance, isolated migrations may occur from the mid-south into this region but rainfall may limit the overall threat. No risk is predicted for Friday night into Saturday, and then Low risks are predicted mainly across the southwestern corn-growing region from Kansas and Nebraska northeast into southern Minnesota and as far east as western Illinois by late in the weekend and early next week. Despite the low overall risk, growers should monitor for second generation moth appearances as well as the potential for new migrant moths from potential flights earlier this week in the next several days.
