The episode as NWS ALY wrote it up.
The remnants of Hurricane Ivan moved across the region during September 17th and 18th, dropping anywhere from three to locally in excess of six inches of rain in many locations across Eastern New York and adjacent Western New England. Hardenburg, in Ulster County, unofficially reported the most with 7.50" of rainfall during the two day event. The heavy rains combined with an unusually saturated ground and a high water table from previous heavy rains, produced significant runoff and resultant flooding across the region. The majority of flood damage sustained from the heavy rainfall was confined to roadways, with many roads, bridges and culverts being washed out by floodwaters. Landslides and serious erosion occurred in the Town of Hardenburg in Ulster County as the Esopus Creek overflowed its banks. Ulster County was especially hard hit as the Emergency Management Official for that county has estimated up to 2 Million dollars of damage to infrastructure, while little if any personal property damage was noted. That county has been declared eligible for aid through FEMA. Personal damage, estimated at nearly half a million dollars was noted in Schoharie County. Additional damage occurred to several docks and boats moored along Catskill Creek and the Mohawk River. Low-lying portions of mobile home parks in the Village of Ravena were also evacuated due to flooding during this event. While power was temporarily shut off and some telephone service was disrupted in many of the flooded areas, no serious injuries were reported.
