Despite recent dry conditions, such high rainfall rates in a short period of time can result in flash flooding, especially in urban and poor drainage areas and where heavy rain repeatedly impacts a given area. Steady rain continues into Wednesday before transitioning to showers Wednesday night into Thursday. Three day rainfall totals likely range from 1 to 3 inches with isolated amounts of 3 to 7 inches across portions of the eastern Catskills, Litchfield County and central and southern Taconics due to upslope enhancements. - http://www.weather.gov/safety/flood
