Patients at Ben Taub Hospital in Houston awaited evacuation as food runs low, according to an article on a CNN website.
Ben Taub is the city's largest Level 1 trauma center, which contains special equipment and staffing for mass casualty events.
It was one of several facilities that upgraded their systems to keep patients safe from floodwaters after Tropical Storm Allison dumped several feet of rain on the area in 2001, the article said.
Although patients are not in danger, a hospital official said they "just need(s) to get enough food to continue to run the house." Ben Taub had about one and a half days worth of food left on Monday.
