The U.S. Census Bureau on Thursday issued some updated data on coastal communities that could be impacted by Earl.
The big number: "26 million people in 68 counties, stretching from North Carolina to Maine, could face hurricane and tropical storm conditions within the next 48 hours."
Another interesting stat: 83 percent of housing units in Massachusetts' Barnstable County, where Cape Cod is located, were built before 1990. That could become important if Earl, as expected, spins close to the Cape Cod area. Older homes tend to be less resilient in storm conditions.
