A cold front moved gradually southeastward across the region during the day Monday, March 7th, as a wave of low pressure moved northeastward along the boundary. To the south of the boundary, it was mild as the area was in the warm sector of the low pressure system. The storm tapped into both Atlantic and Gulf moisture, resulting in heavy rainfall of 1 1/2 to 4 inches across the central and southeastern Catskills, mid Hudson Valley, Taconics and Washington county Sunday, March 6th, into Monday, March 7th. The heavy rainfall, combined with runoff from snowmelt due to the mild temperatures, resulted in widespread flooding of rivers, streams, creeks, and roads.
To the north of the boundary, the rain transitioned to a wintry mix of sleet and freezing rain then snow. Prior to this transition, runoff from the rainfall and snowmelt caused ice jams in Hamilton and Herkimer counties that resulted in some flooding.
Damage estimates are unknown.
