Seems like I vaguely remember having occasional problems with the direct link to Accuweather too. I have my Accuweather link set up as three pages per channel, using the following links:
http://avantgo.accuweather.com/pda/l...?zipcode=xxxxx
http://avantgo.accuweather.com/pda/r...?zipcode=xxxxx
http://avantgo.accuweather.com/pda/s...?zipcode=xxxxx
Haven't had any problems with this.
