how much water is there in the sky?

I mean seriously, the clouds have been just as dark from morning til arvo, and the torrential downpour which caused a widespread natural disaster throughout the school didn't cease during the whole day and web it was raining very hard, it somehow managed to still increase in intensity =/ I swear there isnt thaaaat much water in the sky, although this is prolly a result of the weather system pattern thing called a La Nina or something (I'll get back to this one) and possibly the results of climate change resulting in colder winters, heavier extended periods of downfall, as well as extended periods lack of rain...and no I do not mean drought! anyway, I hate this rain cos its so heavy but not epic...theres no thunder/lightning =( which really does make it all that much more amazing, especially at night even though it does kill your eyes and often results in after-images (where you can still see the image in your view but it has already gone) but heyy, its fun! =D
ok, I have a photo of one of the floods at Baulko...
