Mayor Lyda Ann Thomas on Tuesday announced a "look and leave"

re-entry advisory on the island between the hours of 6 a.m. and 6 p.m.

Galveston residents and business owners are lining up to get into the city. They must show photo identification at highway check points under the policy.

The city was under a mandatory evacuation order before Ike,

which knocked out all medical facilities, water, sewer, electricity

and gas services.
