The rainfall bands from Hurricane Irene have reached well into upstate New York. The high terrain of the region, with the Adirondack Mountains, serves to keep the heaviest of these downpours to the east. A swath from the Canadian border to New York City that centers roughly on the Hudson River has been receiving massive amounts of rain in the last 24 hours. That rain is reflected in increase stream flows and water levels.
The three National Weather Service offices. Burlington, Albany and New York City, within the impacted corridor all report flash flood warnings or flood warnings. NWS is reporting the following rainfall totals (in inches) for the period 8 a.m. to 2 p.m. today.
Glens Falls: 2.46
By 8 p.m., Glens Falls is expected to receive nearly 2 more inches of rain and Albany another inch. Hunter will receive about a half inch more and Poughkeepsie a quarter inch.
The effect of the rain can be seen on a number of gauges. Since midnight, Putnam Creek near Crown Point has gone from a discharge of 14 cubic feet per second (cfs) to nearly 800 cfs. The Bouquet River at Willsboro has gone from 80 CFS to over 300 CFS. The Ausable River has gone from 200 cfs to over 400 cfs. Those streams flow out of the Adirondack Mountains.
The upper Hudson River is also showing the effects of the rainfall from Hurricane Irene. Near Waterford, the river has risen nearly two feet since midnight. At Green Island, the river has risen nearly three feet and the flow has increased from 9,000 cfs to 33,000 cfs.
Further south, YNN reports that Delaware County communities have been hit by severe flash flooding. The county is between Binghamton and Albany and is the northwest portion of the Catskill Mountains. On the Hudson, the NYS Thruway has been closed due to flooding from Newburgh south the Nyack, some 41 miles. The Times Herald-Record reports Newburgh has flooding and that almost all roads in Ulster County are closed.
