HOUSTON – Authorities said more than 13,000 people have been rescued in Houston and surrounding areas.

The majority of those rescued are turning to makeshift shelters for a place to stay.

Shelters have opened up all across the city. The George R. Brown Convention Center is now housing nearly 10,000 people.

The Toyota Center downtown, home to the Houston Rockets play is now a shelter.

Also one of the biggest churches in the nation opened its door for evacuees, Joel Osteen’s Lakewood Church, the former home to the Rockets that seat 16,000 people.

Osteen initially took some criticism for not opening the building, but Tuesday the doors opened wide and people streamed in.

The church is also serving as a drop-off point for diapers, food and other necessities.

Unlike many disasters where people stay in the shelter for a day or two, the impact of this disaster looks like it may linger for a while.
