Today's unusual summer downpour in Perth was certainly welcome respite from the oppressive heat of the past week. It also triggered an unusual situation in my WeatherChart, which simultaneously shows temperature and rainfall for the past 3 days, of the rainfall completely overwhelming the temperature display. To ensure that temperatures are always visible in future I have made the rainfall bars slightly transparent.The Bureau of Meteorology also seems to be in the process of adjusting their data feeds, by adding extra pressure information. For some stations this causes the pressure to register as rainfall, leading to some rather extreme floods. If the change looks permanent then I shall adjust the WeatherChart code accordingly.
Update 9 Feb 2008: I've updated the chart to cope with the occasional extra column of pressure. I also refreshed the list of weather stations, so if your station was missing then now is the time to check again.
