00:41 Hurricane Laura’s Storm Surge Traps Bottlenose Dolphin Miles From the Ocean A bottlenose dolphin got lost in Hurricane Laura’s storm surge and ended up trapped in a landlocked pond for about a week in Louisiana.

It doesn't matter whether Barry ends up staying tropical storm or becomes Category 1 hurricane, says weather.com senior Jonathan Erdman, the rainfall impact will be dangerous in some areas.

Some locations in Louisiana could received 10 to 20 inches of rain and flooding that could linger for days, if not weeks.

"The dangers associated with the storm is reason we're constantly saying 'Don't get caught up in the intensity,'" Erdman said.

Some of the worst flooding on record in Louisiana was caused by an unnamed storm in August 2016, Erdman said. The storm, which wasn't associated with a tropical depression, storm or hurricane, caused $11 billion in damage and was the most damaging flood in the U.S. since Sandy, according to NOAA.

"So it doesn't matter what the storm is called, we're expecting a major rainfall flood event," Erdman said.
