Updated at 10:30 a.m. ET: Residents in unprotected, low-lying areas outside New Orleans were evacuating Monday as Tropical Storm Isaac threatened to strengthen into a hurricane that could make landfall in or near Louisiana almost seven years to the day that Hurricane Katrina struck.

It’s “trying to form an eye-like feature” but it’s “still a little bit shy of hurricane status,” National Hurricane Center Director Rick Knabb said in a morning update.
