Gov. Tom Corbett is declaring a state of disaster emergency for Pennsylvania amid increasingly dire forecasts that show a so-called super storm hitting it and neighboring states in coming days.
Corbett's comes as state emergency management officials urged residents to have three days of supplies at home - including batteries, water and food - in case of widespread power outages.
President Barack Obama has signed an emergency declaration for Pennsylvania.
The declaration will allow state officials to request federal funding and other assistance for actions taken in advance of the huge storm.
Federal forecasters said Friday that a brewing monster weather system involving Hurricane Sandy is expected to pummel the East Coast harder than Hurricane Irene, which last year left hundreds of thousands of Pennsylvanians without power and eventually led to historic flooding.
Sandy is expected to merge with a wintry front to create a mess that some have dubbed ``Frankenstorm'' with hundreds of miles of steady, damaging winds and rain.
