I'm having some problems retrieving weather info for Singapore.
1. First I retrieved "Singapore"'s WOE id -- which is 23424948
$ curl 'http://where.yahooapis.com/v1/places.q(Singapore)?appid={SECRET}'
<?xml version="1.0" encoding="UTF-8"?>
<places xmlns="http://where.yahooapis.com/v1/schema.rng" xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" yahoo:start="0" yahoo:count="1" yahoo:total="2"><place yahoo:uri="http://where.yahooapis.com/v1/place/23424948" xml:lang="en-US"><woeid>23424948</woeid><placeTypeName code="12">Country</placeTypeName><name>Singapore</name><country type="Country" code="SG">Singapore</country><admin1></admin1><admin2></admin2><admin3></admin3><locality1></locality1><locality2></locality2><postal></postal><centroid><latitude>1.365580</latitude><longitude>103.827713</longitude></centroid><boundingBox><southWest><latitude>1.115800</latitude><longitude>103.618248</longitude></southWest><northEast><latitude>1.470620</latitude><longitude>104.408470</longitude></northEast></boundingBox></place></places>
2. Then I requested for weather information using 23424948 -- which Yahoo replies with "City not found"
$ curl 'http://weather.yahooapis.com/forecastrss?w=23424948'
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<rss version="2.0" xmlns:yweather="http://xml.weather.yahoo.com/ns/rss/1.0" xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#">

3. I tried with New York's WOE ID -- 2459115, which basically works.
$ curl 'http://where.yahooapis.com/v1/places.q(New%20York%20City)?appid={SECRET}'
<?xml version="1.0" encoding="UTF-8"?>

I'm not sure what's wrong with the Singapore data?
