"Everything that we've been watching on the news looks like this one will really get us," she said. "We're definitely worried about it."
"I don't want to go through this again," Pacheco told CNN affiliate WPRI-TV in Providence.
The estimated cost of potential wind damage alone is estimated at $2.5 billion to $3 billion, the Federal Emergency Management Agency said.
That estimate doesn't include potential flooding and other damage, though the federal government has preemptively declared states of emergency in a number of locales to help states cope with Sandy and its aftermath.
Classes, trading and campaigning canceled
Officials canceled classes Monday for more than two million public school students in districts such as New York, Philadelphia, Boston and Baltimore, while numerous universities and federal offices in Washington and government offices in states like New Jersey were closed.
The U.S. stock exchanges were closed Monday and may remain closed Tuesday.
The last time the New York Stock Exchange closed for a weather event was in 1985, during Hurricane Gloria. And in 1969, a snowstorm also brought the exchange to a halt.
Although official Washington was shut down, the Supreme Court heard oral arguments.
Politicos from both sides ahead of next week's election said it was still too early to tell what effect the storm would have on the presidential race, though access to voting centers would be a concern if the storm's effects persist.
"I don't think anybody really knows," top Obama adviser David Axelrod said Sunday on CNN's "State of the Union."
"Obviously, we want unfettered access to the polls because we believe that the more people come out, the better we're going to do, and so, to the extent that it makes it harder, you know, that's a source of concern."
Virginia's Republican governor said Sunday that his state would take measures to ensure residents are able to vote despite obstacles the storm might bring. Virginia is one of a handful of battleground states.
Then there are the travel nightmares related to the storm -- thousands of flights have been canceled, Amtrak train runs scuttled and hundreds of roads and highways expected to flood.
"This is not a typical storm. It could very well be historic in nature and in scope and in magnitude because of the widespread anticipated power outages, flooding and potential major wind damage," Pennsylvania Gov. Tom Corbett said.
"Essentially, this is a hurricane wrapped in a 'nor'easter.'"
