Panos said patients will be transferred back when the river's waters go down to a safe level,

"Getting the patients into a safe environment" has been the center's top priority, Panos said. Once that is done, staff members will focus on securing the building.

Harford County Volunteer Fire and EMS Association Public Information Office David Williams likewise said the process was running smoothly and many patients had already been picked up by family members. For those who were being relocated, Williams said they were working with local nursing homes to secure beds.

"Dependent on the worst case scenario, this could be a long term relocation," he said. "This could be a week or longer."

Citizens Care was the first priority, Williams added, and the Emergency Operations Center plans to focus on the Graw, a high rise senior citizen apartment building that is across Revolution Street from Citizens Care Center and less than a block from the Susquehanna River.

A staging area had been set up around the corner from the nursing home with emergency apparatus to be used if necessary.

The Havre de Grace Activity Center, on Lewis Lane, was also closed. All senior, Boys and Girls Club and Havre de Grace Recreation Committee programs scheduled for Friday were canceled.

Some schools closed Friday

Aberdeen City Manager Doug Miller said Aberdeen High School was designated Thursday afternoon as a shelter for anyone who needs it.

Harford County Public Schools announced earlier in the day it had canceled all Friday classes at Aberdeen High and at the four schools in Havre de Grace - Havre de Grace High, Middle and Elementary and Meadowvale Elementary.

School system spokeswoman Teri Kranefeld said Aberdeen High School was chosen to be a shelter because of its close proximity to the flood-affected areas.

While his city seems to be in good shape, Aberdeen's Miller said, "we are concerned on a regional basis, in that this issue with the Susquehanna and all the flood gates opening up, regionally, that's going to affect all of us, and we will stand by to assist Havre de Grace and Harford County as we can."

"We have been told that the high school will be used as a shelter and we will have Aberdeen Police Department available as security for that," he said.
