Just to give you an idea: the afternoon shower yesterday over my area in Singapore brought down about 40mm rain, that's 40 liters per sqm. And that's pretty normal for the season. Now compare this with the statistics of your area.It is monsoon season there now right? Please forgive my limited knowledge... I am reading stuff that folks on other planes in that area reported cloud cover but not necessarily extreme weather...radar images that I have looked at show what appears to be big nasty storms however...
And the Philippines just had another typhoon... so the weather is a bit bumpy here at the moment.
