Matthew: 'Devastating impacts,' and storm of anxiety brewing

Aside from Sandy, which technically was not a tropical storm at landfall, the last 11 years have been blessedly short of hurricane-related damage in the United States.

It remains way too early to determine whether Matthew will have any significant impact on the U.S. mainland.

But at the very least it has the potential to produce one of the more-menacing storm vigils in recent years.

At 5 p.m., it was a Category 4 hurricane about 140 miles south of Haiti, moving north at 7 mph, and packing peak winds of 140 m.p.h., according to the National Hurricane Center.

It is expected to pick up some speed on Tuesday night, and eventually parallel Florida, weaken a bit to a Category 2, and then make a run at the South Carolina/North Carolina border.

More immediately, the hurricane center says Matthew "is likely to produce devastating impacts" on parts of Haiti,

Later the week, attention could turn to the U.S. East Coast.

Regardless of where it winds up going, Matthew is likely to generate a storm of anxiety during the next several days.
