Assuming the APRS infrastructure (digipeaters, a reachable igate and the
Internet at that location) don't get wiped out in the hurricane, it's
quite simple. Compose a an APRS message to be sent to the callsign
"EMAIL" instead of an actual station.
Then, the very first part of the message payload is the actual email
address of the person you are trying to send to. Follow this with one
or more spaces before the actual text of the message. Note that:
1) APRS messages are cell-phone-texting-style one-liners with a max
of less than 80-100 chars.
2) The email address consumes part of the message one-liner. If you
have the choice email addresses, choose one with the shortest adddress
string to use. (For example, an address at "aol.com" will leave more
space for the real message than an address at "sbcglobal.com" or
"earthlink.net".)
3) APRS email is basically a one-way system. You can SEND a message
to any internet email address (and may get an ack back) but the Internet
party can not send a reply back to you. (It's the regulatory issue of a
non-ham party initiating a transmission on the ham bands.)
Since you may be in a less-than-favorable location (relative to any
surviving digis) you want to throw all the antenna gain you can
possibley muster into the mix. An Arrow Antenna collapsable
light-weight hand-holdable yagi would be ideal.
And, if you do use any external ants with the TH-D7;
DON'T FORGET AN SMA-to-BNC or SMA-to-UHF ADAPTER!!
