Some 14 trillion gallons of rainwater are forecast to fall on Louisiana, Mississippi and Arkansas during Barry. Three million people may be impacted.

Hurricane Barry made landfall near Intracoastal City, Louisiana, Saturday but quickly weakened to a tropical storm as sustained winds slowed. 

The storm still poses the threat of heavy rainfall as it moves northwest through Louisiana, the National Hurricane Center said. 

Governors have declared emergencies for Louisiana and Mississippi, where people have been ordered to evacuate or shelter in place with at least three days' worth of food and supplies.

More than 100,000 people were without power as the storm hit Louisiana’s south-central coast Saturday morning, according to the tracking site PowerOutage.us

Louis Armstrong New Orleans International Airport announced that all flights Saturday were canceled.

The storm left some roads underwater, and wind gusts knocked out power. Here is what was known Saturday night as the storm slowly made its way northward.

Where is Barry now? 

As of 8 p.m. EDT, the National Hurricane Center reported that Tropical Storm Barry was about 55 miles northwest of Lafayette, Louisiana, and had sustained winds of 60 mph. The storm was moving north-northwest at 7 mph.

Where did it make landfall? 

Barry landed at Intracoastal City, about 150 miles west of New Orleans, as a Category 1 hurricane – the nation's first hurricane of the year. 

It had sustained winds of 75 mph, but soon weakened to a tropical storm as it moved inland, the National Hurricane Center said.

What is the forecast?

Forecasters said that Barry would push through southern Louisiana Saturday and the northern part of the state Sunday.  The storm is expected to weaken to a tropical depression Sunday.

Still, the storm could dump 10 to 20 inches of rain through Sunday across Louisiana, as well as southwestern Mississippi. Some areas of Louisiana could get as much as 25 inches of rain. 

Flash flooding will become increasingly likely in south-central and southeastern Louisiana, as well as areas of Mississippi, through Sunday. The slow-moving storm will bring long periods of heavy rain, the NHC says.
