Since you live in the tropics your rain is probably stepwise from light to holy hell!!!! I have seen low 80s versus 90s make a difference in Maryland. True when it drops to zero, it drops. But the same storms I had problems with last year with high 70s to low 80s are not a problem now that I am in high 80s low 90s. (almost everyone gets a range of 5-10 points on transponders).
