Though it was downgraded this evening to a Category 2 storm and forecast to weaken slowly as it moved northward, officials up and down the East Coast still were bracing for a powerful punch.
By 11 p.m. ET, Earl was about 115 miles south-southeast of Cape Hatteras, N.C., according to the National Hurricane Center (NOAA). The eye of the storm was expected to stay offshore for now.
President Obama signed an emergency disaster declaration for Massachusetts late Thursday. Earlier, Massachusetts Gov. Deval Patrick declared a state of emergency ahead of the storm after officials extended a hurricane warning to the state's southern coast. He said the declaration will help Massachusetts respond to the storm, expected to pass the area late Friday into Saturday.
Rhode Island Gov. Donald Carcieri made a similar emergency declaration, The Associated Press reported.
In neighboring Connecticut, Gov. M. Jodi Rell asked President Obama to issue a pre-landfall declaration of emergency to ensure federal funding help with the storm response.
At 11 p.m., tropical storm warnings or watches were extended up the Massachussetts and Maine coasts and into Canada, according to NOAA.
