The surfeit of moisture first from snow and then from rain in Grand Rapids, Michigan, in 2019 year-to-date is characteristic of much of the continental United States, more than 80% of which isn't even abnormally dry at the height of summer at the end of the first week of August 2019. Drought is isolated to pockets making up less than 5% of the Lower 48, particularly near Seattle.
