What happened
The episode as NWS BGM wrote it up.
A front from southern New England to near Washington D.C Sunday morning the 25th moved slowly west to a position from just north of New England, south-southwest across the Adirondacks through central New York, and then down the spine of the Appalachians by Monday morning the 26th. Tropical moisture moved westward and engulfed nearly all of New York State and most of northern and eastern Pennsylvania by Monday morning. This resulted in a widespread area of moderate to heavy rain across all of central New York and northeast Pennsylvania including the Poconos and Catskills by Monday morning the 26th. The heaviest rainfall occurred in the Poconos and Catskills where rainfall amounts totaled between 1.5 and 4 inches by 8 am EDT Monday. In Delaware county, flash flooding began around 6 pm Monday evening as another batch of heavy rain concentrated extreme rainfall again over much of Delaware County during the day Monday. With the soils saturated from Sunday and Sunday night's rainfall, major flash flooding began. The town of Colchester took the brunt early on and the residents evacuated voluntarily. All roads in the town of Colchester were closed as of Monday evening.
