Quarterly Climate Impacts and Outlook for the Great Lakes Region for June – August 2017. Dated September 2017.
Many locations in the Great Lakes basin received above-normal precipitation this summer, with some locations receiving record-breaking precipitation. For example, Avon and Watertown (NY) experienced their wettest summer since records began in 1896 and 1950, respectively. Bouts of heavy precipitation resulted in several flash flooding events across the basin, with notable events in all three months. One such event occurred from August 28-29, when rainfall totals of 220 to 290 mm (8.7 to 11.4 in) fell in Essex County, Ontario and resulted in significant flooding to roads and basements.
NOAA’s Regional Climate Services Program created these Climate Outlooks to inform the public about recent climate impacts within their respective regions. Each regional report contains easy-to-understand language, and anyone can access them through the Drought Portal at https://www.drought.gov/drought/resources/reports.
