Excessive Rain/Moderate to Major Flood Event
Following within a week of the major rain storm that closed out March, a second moisture rich and vigorous storm again dumped excessive rains over much of the region. This time, due to the already saturated and still in some places frozen ground, the melting of the remaining snow pack in the mountains, and the high water lingering from the late March storm, moderate to major flooding occurred along all the major rivers as well as along the smaller streams and creeks. States of emergency were declared late Saturday continuing into the day on Sunday for Delaware, Otsego, and Schoharie counties where flooding was most severe. At one point during the height of the rain Saturday night, every road in Delaware county was closed due to flooding.
This storm originated in the very active and moisture rich southern branch of the jet stream, allowing it to first track through the Southeast, where it produced heavy rain and severe weather during the day Friday, April 1. The system got a real kick when a disturbance moving towards the southeast in the northern branch of the jet phased with it, creating a very large and very intense cut-off low pressure system in the upper levels of the atmosphere. The storm moved very slowly to the east-northeast up the Appalachians and eventually into the Northeast. A deep and broad south to southeast flow around the storm's center was able to transport huge amounts of moisture into Pennsylvania, New York, and New England supporting the locally torrential rain that began during the pre-dawn hours on Saturday and continued into Saturday night.
And it was a chilly rain during the morning and afternoon on Saturday as temperatures only slowly climbed into the mid and upper 40 by the evening. A warm front lifted north through the region during the evening allowing a strong and gusty south to southeast flow to develop that pushed temperatures to near 60° by midnight. The warm up was brief, though, as temperatures gradually dropped through the 40s during the day on Sunday in most spots but into the 30s in the higher elevations. Rains became more showery in nature on Sunday and mixed with snow in the hills as the colder air wrapped all the way around the low, coming in from the south. The storm lingered over the Northeast through the day Monday, April 4, but only produced very light mixed rain and snow showers during that time. The storm's last lingering effects on the 4th was more from the low overcast, gusty winds, and unseasonably chilly temperatures in the upper 30s and low 40s, than from the lingering showers. (Moderate to heavy snow fell on the western side of the storm with widespread power outages and road closures due to heavy snow accumulations across eastern Ohio, western Pennsylvania and western New York.)
The axis of heaviest rain with the storm came up through Baltimore and Washington, through much of central and eastern Pennsylvania up through central New York including Otsego, Delaware, Ulster, Schoharie, and Greene counties, where rainfall totals ranged from 3"-5" on average. Rainfall, although still significant, was lighter and more intermittent north and east of that axis, running up through the Mohawk valley, Adirondacks, Capital Region, and western New England where rainfall amounts ranged from 1"-1.7" on average. The deluge in the Catskills produced locally severe flooding Saturday afternoon through Sunday. The lighter rains elsewhere were also enough to trigger all the major rivers to go into minor to moderate flood on Sunday into Sunday night.
All the major rivers, including the Schoharie Creek, the Mohawk, the Hudson, the Esopus Creek in Ulster County, the Schroon River in Hamilton County, the Mettawee River in Washington County, the Otter Creek in Rutland County, VT, the Housatonic River in Berkshire and Litchfield Counties, as well as all the smaller streams and creeks, went over flood stage by Saturday night and Sunday. Flooding was most significant on the Schoharie creek, where parts of Middleburgh and Schoharie were inundated, although not as severely as in the floods of 1987 and 1996. Moderate flooding occurred on most of the other waterways including the Mohawk at Waterford, and in the Schenectady Stockade area, the Hudson from Granville down to Troy, where water inundated river street in Troy, flooding the parking garage of the Troy City Hall. The Mettawee inundated parts of Granville in Washington county and the Housatonic produced minor to in places moderate flooding along its length in Berkshire county, MA.
Along with the rivers and streams, significant ponding on roads, low areas, as well as countless basement floods occurred during the height of the rain especially in the Catskills where the rain was most relentless through Saturday night.
The flooding situation improved rapidly on Sunday along the smaller streams and creeks, as water levels began dropping rapidly after the conclusion of the rain. The major rivers remained in flood, however, into the day on Monday, but with water levels dropping. By Tuesday, April 5, all remaining flood warnings for area rivers had either been cancelled or had expired.
