From CNN:

Four governors declared states of emergency Thursday as Hurricane Irene threatened to wreak havoc along the United States’ Eastern Seaboard.

Virginia Gov. Bob McDonnell, New Jersey Gov. Chris Christie and Maryland Gov. Martin O’Malley declared emergencies for their states, while North Carolina Gov. Beverly Perdue declared a state of emergency in counties east of Interstate 95. The emergency declarations allow states to free funds and prepare resources that may be needed.

The Washington Post has a terrific tracker page.

It will likely be a tropical storm by the time it hits where we live.
