The status of the Taringa Rovers grounds is shown on the home page top right-hand side - see here.
The status of away grounds is listed at www.fqmetro.com.au/wet-weather/junior-weather-updates/
Note that it is the status of the ground that determines whether or not a game goes ahead, not necessarily the weather. If rain forecast or after a rain period it's a good idea to check the status of the ground just prior to leaving home.
