More than 800 000 customers in 14 states from Michigan to Virginia to Maine were left without power. According to estimates, at least 51 to 127 mm (2 to 5 inches) of rain fell in parts of eastern Pennsylvania and eastern New York on October 31.

On November 1, officials released flood emergency warnings for the village of Frankfort in southern Herkimer County, New York, though 11:30 LT.
The harsh weather prompted authorities to close several roads. People also got trapped in their homes and vehicles.
We cannot overstate the importance of staying off the roads. Emergency services personnel are actively conducting water rescues for motorists that have driven into flooded zones and have become endangered.
Please do not drive unless it's an absolute emergency.
