"We want to make sure that everyone is adequately prepared," said AJ Suero, regional communications manager for Red Cross Pennsylvania.
Suero is among those who are in the Carolinas, Georgia and Florida helping nearly 7,000 people.

Officials also say to never pay by gift card or wire transfer. Credit card and checks are safer.
Also, watch out for names that look like well-known charities and be sure to search charity names online. Others may have left reviews.
Ask how much of your donation goes to the program you want to support.
"Know that when you donate (to the Red Cross), you are helping the people impacted by Hurricane Dorian," Kluthe said.
Red Cross officials are also urging those in unaffected regions to donate blood.
Roughly 70 blood drives and donation centers had to be canceled and now there is a major need.
