Harvey makes landfall in Louisiana

The National Hurricane Center says Harvey is back on land after coming ashore early Wednesday just west of Cameron, Louisiana. The tropical storm is expected to weaken and continue to the north.

The storm returned to land about 5 miles west of Cameron with maximum sustained winds of 45 mph.

Harvey is forecast to drop substantial amounts of rain on Louisiana before moving on to Arkansas, Tennessee and parts of Missouri, which could also see flooding.

The latest weather forecast predicts less than an inch of rain and perhaps even sunshine for the Houston area.

However, the dangers remain far from over. Authorities and family members have reported at least 18 deaths from Harvey, while law enforcement agencies say more than 13,000 people have been rescued in the Houston area and surrounding parts of Southeast Texas.

Houston Mayor Sylvester Turner also implemented a curfew of midnight to 5 a.m. in an apparent response to scattered reports of looting. Police Chief Art Acevedo said violators would be searched and arrested.

Two additional shelters - the Toyota Center and NRG Park - opened to house displaced residents. Louisiana's governor also offered to take in Harvey victims from Texas, and televangelist Joel Osteen opened his Houston megachurch, a 16,000-seat former arena, after critics blasted him on social media for not acting to help families displaced by the storm.

A shelter near Houston for at least 100 displaced people has been overrun by Harvey floodwaters, forcing weary evacuees to retreat to bleacher seats.

Jefferson County sheriff's deputy Marcus McLellan said Wednesday that the Bowers Civic Center in Port Arthur was inundated overnight due to overwhelming rainfall and a nearby overflowing canal.

Cots and belongings have been abandoned on the civic center floor, which is under about a foot of water.

McLellan says it's not clear where the evacuees will go. Some have been at the civic center since Monday.

He says he's not sure if a Salvation Army shelter in Beaumont has space, and the Beaumont Civic Center can hold 600 people but it's already at capacity. Beaumont is just northwest of Port Arthur.
