Most members of F1's travelling circus touched down in Sao Paulo this week and cursed not packing an umbrella.
Championship chaser Nico Rosberg just beamed at the monsoonal-like conditions.
"If it's raining all weekend, that's just fine," the German news agency SID quoted him as saying on Thursday.
That's because Rosberg is 24 points behind his on-form Mercedes teammate Lewis Hamilton with just two races left to run.
I don't really care as long as I have one point more at the chequered flag in Abu Dhabi, I don't care why or how.
The German has already declared that he doesn't mind at all if the Abu Dhabi finale's 'double points' novelty is highly controversial.
"I don't really care," said Rosberg, "as long as I have one point more at the chequered flag in Abu Dhabi, I don't care why or how."
For the same kind of reason, he doesn't mind at all if incessant, heavy, changeable or unpredictable rain at Interlagos shakes up the natural order.
"Now it's up to me to make the most of the last two races and to seize every opportunity. It will be difficult, but I will give everything until the chequered flag in Abu Dhabi.
"Full attack," he concluded.
