New York's Bellevue Hospital is evacuating 500 patients due to storm damage.

Mayor Michael Bloomberg says officials are in the process of finding beds for the patients.

Workers have been pumping about 17 million gallons of water out of the basement. Bellevue has been diverting some patients since initially losing power during Monday night's storm.

It has been operating on backup generators since then, but even with backup power operating the outage knocked out key medical equipment and left many hallways and rooms in the hospital dark.

Elsewhere on Monday night, rescuers and staff at New York University Langone Medical Center evacuated 300 patients after it lost generator power due to the storm.
