Raining in Our Parade

From PAGASA Baguio:

October 1 -- 0.4 mm of rain
October 2 -- 20 mm
October 3 -- 531 mm
October 4 -- 38 mm
October 5 -- 4.6mm

And le deluge

October 6 -- 260 mm
October 7 -- 276 mm
October 8 -- 685 mm
October 9 -- 73

October 10 -- O mm. The recorder even forgot to place that. Ay Oo nga ano?
So simple arithmetic:
The three days gave us 1,221 mm or 1.221 meters of rain
The time that Typhoon Parma was here, we had 1.815 meters of rain. BSU even recorded 761 mm of rain in October 8 so La Trinidad was even wetter. Benguet is 4,378 square kilometers in area. Add Baguio's 53 sq km. and we get 8.042 billion cubic meters of rain. Some were absorbed by the soil and most fell down to La Union, Pangasinan, Ilocos Sur, Nueva Ecija, Nueva Vizcaya and Ilocos Norte. Imagine that?
