I am much too far away to receive any of that. You would need to be quite close to or in the affected area to hear them. Pretty sure any operating GMRS repeaters in the affected area are being monitored. But anyone that is safe and close enough might hear someone on FRS, GMRS simplex or CB. The range is quite limited for either. At best 2 miles and usually much less. I wouldn't depend on either for effective disaster comms.
99% of FRS/GMRS radio owners don't use or know of repeaters.
During a previous hurricane here in Central Florida, mostly flat ground, I advised my neighbors via NEXTDOOR to use FRS1 CSQ during the storm. I was surprised how very active it was and the only fly in the ointment that some parents ignored my advice to keep kids from playing on FRS1.
Henderson County NC has a map of families where contacts were made and where none was made. The map is quite evenly dotted, meaning that a family with contact outside could easily make radio contact with ones who have no communications. For whatever reason hiking to those neighbors might be treacherous or impossible.
FRS has indeed been useful in one rescue in Oregon where a hiker was heard 80 miles away by kids playing with FRS radios. The mountains can help, helicopters with radios, even just receivers, can help. I am surprised (maybe not) that the ARRL has not suggested this.
