The flood of November 3-4, 1927, stands as the greatest natural disaster in Vermont history. Devastation occurred throughout the state, with 1,285 bridges lost, countless homes and buildings destroyed, and hundreds of miles of roads and railroad tracks swept away. The flood waters claimed 84 lives, including that of the Vermont Lieutenant Governor at the time, S. Hollister Jackson. Rainfall during the month of October averaged about 150 percent of normal across the state. In northern and central sections, some places received 300 percent of normal. Heavy rainfall periods during October were separated enough so flooding did not occur. Instead, the rain caused the soil to become saturated. Combined with the lateness in the year and the fact that most vegetation was either in, or near, seasonal dormancy, any further rainfall would runoff directly into the rivers. This is exactly the scenario that led to Vermont's greatest disaster. Rain began on the evening of November 2, as a cold front moved into the area from the west. Rainfall continued through the night with light amounts being recorded by the morning of the 3rd. Rainfall intensity increased during the afternoon of the 3rd as a storm moved up along the east coast. This storm contained huge amounts of moisture associated with the remnants of a former tropical storm. A strong southeast flow developed off the Atlantic Ocean. This moisture-laden air was forced to rise as it encountered the Green Mountains, resulting in torrential downpours along and east of the Green Mountains on November 4.
