UPDATE: Sunday, 4:30 p.m.— In a press conference, Gov. Tom Corbett said when the "Frankenstorm" (Hurrican Storm Sandy mixing with a Nor'easter) turns into Pennsylvania Monday, it could bring "unprecedented" flooding and power outages. Small streams and rivers are expected to flood and sustained winds will affect the entire state. What will make it worse, Corbet, said, is that it will be a full moon, creating higher tides in addition to flooding.
Corbett has asked the Federal Government for disaster assistance. He has put 1,600 National Guard troops on standby. And if you live in a flood prone area, he said, be prepared to evacuate. When the weather starts Monday afternoon, Corbett urges residents to stay home and off the roads.
State and federal officials on Saturday night warned Pennsylvania residents to prepare for widespread flooding and power outages caused by Hurricane Sandy.
The storm, which is expected to come ashore along northern New Jersey late Sunday into early Monday, is expected to affect 50 to 60 million people along the East Coast.
States of emergency have been declared in Maryland, New York, Virginia, Washington D.C. and Pennsylvania. Gov. Tom Corbett declared the emergency Friday after forecasters predicted the storm will put Pennsylvania in the flood zone.
Flooding is the main focus of forecasters and federal disaster response agencies for now, according to Louis Uccellini, director the National Oceanic and Atmospheric Administration Center For Environmental Prediction.
Uccellini said the "extent of heavy rainfall has a danger of flooding for Pennsylvania and Maryland and into northern Virginia."
Sandy is expected to merge with a nor'easter to create a "Frankenstorm" hundreds of miles wide, bringing damaging winds and rain.
"Given the amount of rainfall and the period of time that it's falling over, we expect river flooding to be significant from about 48 hours from now on," Uccellini said. "We're looking at the river valleys in Pennsylvania and Maryland then into New Jersey very carefully."
Officials in Bucks County and Montgomery County on Friday called for residents to prepare for the storm by having three days of supplies at home—including batteries, water and food—in case of widespread power outages.
"Every storm is different," said Rick Knabb, director of the National Hurricane Center, "so if you were not impacted by a past storm that doesn't mean it will be exactly the same for you this time."
Federal forecasters said Friday that the "Frankenstorm" involving Hurricane Sandy is expected to smash into the East Coast harder than Hurricane Irene, which left hundreds of thousands of Pennsylvanians without power and led to historic flooding in late August 2011.
"So, there's going to be an inland flood potential," Knabb said. "This is not just going to be a coastal event, although the hazards do start at the coast with the storm surge and exactly who gets the worst of the storm surge is difficult to pinpoint right now."
Also of concern to officials are the strong winds that are expected to cause extended power outages.
"Based upon the wind speeds, we don't expect substantial structural damages," Federal Emergency Management Agency Administrator Craig Fugate said. "What we think the primary impact is going to be is trees and tree limbs down and whatever roof damage from trees coming down as well as power lines. The primary concern with wind is going to be extensive, perhaps widespread power outages due to trees coming down, limbs coming down."
The large size of the storm, which could potentially cover the eastern third of the country, will cause multiple weather-related issues that will vary from region to region.
Once the storm makes landfall, it is expected to track east to west before heading north and being taken up by a storm system coming out of Canada.
