Incident Annex: Tropical Cyclones (Hurricanes)

A tropical cyclone, also called a hurricane depending on its location and strength, is a storm system characterized by winds reaching a constant speed of at least 74 miles per hour and possibly exceeding 200 miles per hour. On average, a hurricane's spiral clouds cover an area several hundred miles in diameter. The spirals are heavy cloud bands from which torrential rains falls. Tornado activity may also be generated from these spiral cloud bands. Hurricanes are unique in that the vortex or eye of the storm is deceptively calm and almost free of clouds with very light winds and warm temperatures. Outside the eye, a hurricane's counter-clockwise winds bring destruction and death to coastlands and islands in its erratic path. High winds and heavy rains from hurricanes impact inland regions many miles from the coast.


A. General

1. Tropical Storms are cyclonic disturbances with winds between 39 and 74 mph (34 - 64 knots).  A tropical storm may develop into a hurricane and is usually accompanied by heavy rainfall.

2. Hurricanes are major cyclonic disturbances with winds of 74 miles per hour (64 knots) or higher that normally occur between 01 June and 30 November of each year (Hurricane Season), with maximum frequency during August, September, and October.

3. In addition to high-wind concerns, a hurricane will normally cause a storm surge which may exceed 20 feet above mean sea level, causing serious damage and disruption of services.

4. Directors/Managers shall develop department/unit-specific plans to meet the requirements of this plan and the needs of their departments/units.  Checklists are encouraged where detailed steps are required to meet preparedness needs.

B. Planning

1. Pre-Hurricane Season: By 1 June of each year, all areas/units will conduct the following:
a. Educate employees on Hurricane Plans.

b. Review material requirements, and provide a list of special or extra materials to Materials Management. 

c. Departments should develop provisions to relocate critical equipment and documents from external facilities into protective areas as needed.

2. Hurricane Season:

a. All areas/units will keep their disaster manual updated at all times and keep the Emergency Preparedness Subcommittee informed of "exception" issues.

b. The Safety Officer will monitor tropical storm activity and keep Administration informed of concerns.

c. The Emergency Preparedness Subcommittee will assist areas/units with planning as required.

d. Engineering and Security will conduct frequent inspections of hospital facilities and grounds to ensure general readiness to withstand tropical storm force winds (39-74 mph) at all times.  Missile hazards (items/materials that can be carried by strong winds) shall be monitored closely and action taken to secure them during storm warnings and/or hurricane alerts.

e. Engineering shall monitor contractors to ensure their ability to respond to hurricane preparedness requirements.


A. Hurricanes are one of the most destructive forces of nature encountered along the Mississippi Gulf Coast. Hurricane winds and related tidal activity can cause major damage to facilities and serious injury to people.  This Hurricane Plan has been developed in order to minimize the impact of a hurricane on MHG operations, facilities, patients, and employees.

B. Administration will issue a hurricane pre alert status when the Hospital is located within the probable strike zone.  When a pre-alert status has been called, employees will begin implementing their personal plans and get prepared to be placed on full Hurricane Alert Status on short notice. 

C. MHG Hurricane Alert Status (HAS).  When a major tropical storm or a hurricane threatens the Mississippi Gulf Coast, the Hospital President/CEO or his designee may place the hospital in a Hurricane Alert Status, depending on the projected landfall and severity of the storm.  When HAS is implemented, all departments will activate the Hurricane Alert Status Tasking as outlined in this plan.

D. Full implementation of HAS may not be necessary.  Consideration will be given to the National Hurricane Center projections and strength of the storm.  Hospital Administration may modify the phased tasking outlined in this plan, as appropriate for the level of threat presented by a Category I Hurricane (wind speed 74-95 mph).


A. Normal supervisory control will be maintained throughout the Hurricane Alert Status.

B. The Hospital President/CEO will assign a Incident Commander to direct emergency operations during the Hurricane Alert Status.

C. The Incident Commander in the Hospital Command Center (HCC) oversees and coordinates activities for hospital personnel during a hurricane.

D. Coordination with local agencies (Harrison County Emergency Operations Center, Police, Fire, etc.) for emergency support will be accomplished by the HCC.


A. The Hurricane Team consists of employees designated by the Directors/Managers to provide essential staffing during the hurricane season.

B. Directors/Managers will take measures to minimize staffing during a Hurricane Alert Status.  The ability of the hospital to support (house, feed, and care for) personnel seeking shelter is extremely limited.  

1.  Disciplinary action, up to and including termination, may result for failure to report for duty, or to complete duty assignments, during a disaster including hurricanes

2.  An employee must receive approval from his/her manager prior to making assignment or schedule changes.

C. The Hurricane Team is discouraged from bringing their dependents to the hospital.   Whenever possible, dependents should go to a community shelter or leave the Coast.  If no other arrangements can be made the employee will have to request an exception. Exception requests must be submitted to the employees' Manager who will forward it to Administration for final approval.

D. The President/CEO or designee will determine when non-essential personnel should be released and the Hurricane Team activated.  Employees assigned to work or requested to be present at the hospital will be on a waiting to work status.  All hours will be computed as hours worked and employees will be paid according to their status. 

E. Medical Staff personnel will be coordinated by the Chief of Staff and the Director of Medical Staff Services.

1. The Chief of Staff will be responsible for physicians in the hospital and for assigning them to areas of responsibility.  The following specialties will be available: Pediatrician; Obstetrician; Urologist; Orthopedic Surgeon; Neurosurgeon; Anesthesiologist; Family Practice; General Surgeon; Internist; Hospitalist; Psychiatrist; Radiologist; Cardiac Surgeon; Cardiologist; and Pulmonologist.

2. Any physician who wants to be in the hospital during the emergency may come in and will be assigned to medical duties as needed.

3. Patient care areas will contact the patient's regular physician as necessary and if possible, but if the physician is not available, an in-house physician will care for any patient.

4. Physicians should be discouraged from bringing their dependents to the hospital during HAS.

5. Medical Staff Services will register physician family members, report occupancy to the HCC, and provide a list of physicians and family members present at the hospital to Human Resources.

6. If when the Medical Staff Departmental plans are implemented there is any physician specialty, as noted in Section E.1 that remains uncovered, the Chief of Staff, or his designee, will contact the on call physician for that specialty to provide coverage.


A. Memorial Hospital is not a shelter.  All persons seeking shelter should report to one of the local shelters.  Locations will be announced by the Harrison County Emergency Operations Center.

B. Employees released from work should seek shelter in local hurricane shelters instead of the hospital.
