A remnant of Hurricane Isaac, drawn back to the Gulf of Mexico after an odyssey through the Midwest, hovered Wednesday off the Gulf Coast.
Meteorologist Shawn O'Neill of the National Weather Service in Slidell called it the "spawn of Isaac."
The National Hurricane Center gives the disturbance a 40 percent chance of becoming a tropical depression over the next two days. If it does develop, O'Neill says it probably would get a new name, but that's a matter for the hurricane center to decide.
He says the disturbance is likely to move generally south and hang around in the Gulf until Friday or Saturday, when a cold front should shunt it east or northeast.
Isaac came ashore in Louisiana the night of Aug. 28-29, with heavy rain and storm surges.
