Morning sounding from Lake Charles, LA shows southwest flow above 400mb that will start shearing #Laura near the time of landfall. This could halt intensification or cause slight weakening just before landfall. Unfortunately, it will be too late to prevent a Cat 3-4 strike. pic.twitter.com/3lgJ9YSe5M
