Rain and wind are expected to pick up today for the New Orleans area.
"We're already starting to see some of the rain bands move into Southeast Louisiana," National Hurricane Center Director Ken Graham said.
He says the fact that Tropical Storm Barry has only been moving at five miles per hour is not good news.
"The longer this hangs around... you start getting this heavy rainfall."
Graham says he is very concerned about possible flooding.
"We have to keep talking about the dangers of heavy rain," he insisted. "Ninety percent of fatalities in these tropical systems is indeed the water, and that's the problem we are going to have again."
