Alert Details

Two weather features may lead to some isolated corn earworm moth flights over the next 24 hours: one being a low pressure system and cold front expected to move southeast through much of the corn-growing region by tomorrow night and the other remnants of Hurricane Laura passing through the mid-south and eventually Ohio River valley. Southerly winds in advance of the cold front and on the east side of Laura may result in some isolated corn earworm moth flights especially into the eastern corn-growing region, mainly along/south of I-90 and I-94 and east of I-35. Most likely area for any flights directly associated with Laura would be across portions of Indiana, Ohio, and Kentucky where the majority of crops are too far along in growth where there is much of a concern at this point. Further west, southerly winds may lead to additional moth flights but under less than idea conditions due to wind flow around Laura. Once these systems merge and move east by Friday night into Saturday, little to no additional migration risk is predicted for the weekend and into early next week as northwest flow returns to much of the corn-growing region and any southerly wind events should be of brief duration.
