I live in Orlando.
Don't worry about her too much. In some cases, the cable is down. We lost our cable modem during Hurricane Charley. If she has a telephone modem and not a cable modem, we lost out telephone line for two days with Hurricane Frances.
Our electricity came back on late Monday after being out for two full days.
No sense worrying too much--it probably is lack of communication ability.
Thanks. I'm sure I will hear from her as soon as she can contact me. It's just that she is 75 years old and alone. She refused to leave her condo to go to a shelter.
The Red Cross and Salvation Army use amateur radio to transmit "Disaster Welfare Inquiries" into the stricken area, and back out again.
