What happened
The episode as NWS GYX wrote it up.
A strong south to southeast flow developed across New Hampshire as a low pressure center developed just south of Long Island, NY and moved northward up the Hudson River Valley during the early morning hours of the 28th. Small rivers and streams began to flood by late afternoon on the 28th as about 1.5 inches of rain fell in the area. The rain combined with melting snow to cause small rivers and streams to rise resulting in road washouts in Guilford, Laconia, and Tilton. The Saco River in Conway was above flood stage from 6:30 pm on the 28th until 430 am on the 29th. The Saco crested at 9.5 feet at 10 pm on the 28th, about 0.5 feet above the 9 foot flood stage.
