If you have a loved one in a mandatory evacuation zone, please either go pick up this person and bring them to a safe area or alert authorities in that area if you can't physically get there yourself. Considerations for the elderly who may evacuate include: taking any specialized medical equipment, such as oxygen; making sure an adequate supply of medication is available and packed, important papers are gathered (insurance, medical IDs, wills, etc.); as well as comfort items, such as bedding, clothing, snacks, etc.
If a senior has medically necessary equipment running that requires electricity, make sure that they know about the possibility of power outages during and after a storm. It may be much better to take the equipment and evacuate for a short time, instead of being without a needed or critical device in a crisis situation.
There are shelters set up for those with special needs. Check out the South Carolina Emergency Management Division's website by clicking here. They have important information regarding any emergency declarations, shelter locations, business and government closings and more.
