KEY WEST, Fla. — Tropical Storm Isaac barely stirred Florida Keys residents from their fabled nonchalance Sunday, while the Gulf Coast braced for the possibility that the sprawling storm will strengthen into a dangerous hurricane by the time it makes landfall there.
It was on course to strike land on the seventh anniversary of Hurricane Katrina, a powerful storm that crippled New Orleans and the Gulf Coast. Forecasters expected Isaac to pass the Keys late Sunday before turning northwest and striking as a Category 2 hurricane somewhere between New Orleans and the Florida Panhandle on Wednesday.
The National Hurricane Center issued a hurricane warning for a large swath of the northern Gulf Coast, including New Orleans.
Louisiana Gov. Bobby Jindal called a state of emergency and suggested that people begin leaving low-lying parts of the state.
An emergency declaration was also issued in Mississippi by Gov. Phil Bryant amid concerns of storm surge threatening low-lying areas. Oil companies began evacuating workers from offshore oil rigs and cutting production in advance of Isaac.
The storm was on a course to pass west of Tampa, but it had already disrupted the Republicans' schedule there because of the likelihood of heavy rain and strong winds that extended more than 200 miles from its center.
