Or if you're an APRS user, just send an APRS message (any content except a valid APRS callsign-SSID) to ISS. The response will contain the next pass information for your last beaconed position (or the last beaconed position of the callsign-SSID that you send as the text to ISS). Unfortunately, I don't (yet) flag the visible passes.
The response message format is described at http://aprsisce.wikidot.com/doc:satsrv and the response server works for other satellites as well.

Hello Everyone,
This is a quick reminder that there are several ISS eyeball viewing opportunities this week for North American stations. They are evening passes. On a couple passes you may be able to watch the ISS enter eclipse.
Use your tracking program or the tracking resources on-line:
http://www.heavens-above.com will print you a table of 10-day visible passes if you enter your city data.
NASA's SkyWatch Web site at http://spaceflight.nasa.gov/realdata/sightings/ allows access to USA and global visible passes, and a downloadable SkyWatch 2.0 applet.
http://spaceweather.com/flybys/ may perhaps be using old keplerian elements as it says nothing is visible. Check your keps - there have been a couple of recent ISS reboosts.
