The advisory primarily affects residents and visitors in low-lying areas of Key West, Florida. Minor saltwater flooding could lead to hazardous driving conditions, particularly in areas with standing water. Overflowing storm drains and overtopped seawalls may also pose risks to infrastructure and property. Boaters should be cautious of reduced clearance under fixed bridges, which could impact navigation. While the flooding is expected to be minor, it may still cause inconvenience and localized disruptions.
