Alert Details

Remnants of Hurricane Beryl will affect the southeastern portion of the corn-growing region especially along/east of the I-55 corridor from southeast Missouri northward to near Chicago, Illinois and points east. Historically, tropical systems with tracks similar to Beryl have resulted in some localized corn earworm moth flights into the corn-growing region, with origin points varying from the Caribbean islands to Mexico. Thus, Low risks for isolated but potentially intense moth flights/drop-outs are in the forecast along/east of I-55 for the rest of today into tomorrow. Once this system moves through, then attention focuses on a developing low pressure system in the High Plains by late week and into the weekend. This system does not look particularly strong nor do its associated southerly winds, but with a larger percentage of crops now at critical growth stages (tasseling/silking) and a large percentage of sweet corn now silking, risks are warranted especially south of I-90 and west of I-57 even in less than ideal conditions for Friday and into the weekend.
