A low pressure system that formed on a frontal boundary helped produce showers and thunderstorms with very heavy downpours and led to flooding and flash flooding in Delaware. The heaviest rain fell during the first half of the day in Sussex County, into the afternoon in Kent County and into the evening in New Castle County. About 40 roadways were flooded and closed in Kent and Sussex Counties. While nearly the whole state received an inch of rain, sections of Kent and Sussex Counties received 4 to 8 inches and these locations had the worst flash flooding.
