Heavy Rainfall September 30 - October 01, 2010

An upper level low pressure system interacting with abundant tropical moisture from the remnants of Tropical Storm Nicole dropped 3 to 6 inches of rain across central New York. Steady and occasionally heavy rain fell across much of the region, causing flash flood problems, as well as minor to moderate flooding of the larger main stem rivers. The rain and flooding began on September 30 and continued into the overnight and next day (October 1), especially across parts of the Catskills. Higher amounts of rain fell across Delaware county in the western Catskills, where 6 to 8 inches of rain caused more serious flood problems.
