Scattered rainshowers during the whole day, rains (with strong winds) heavier in the afternoon and noticeable is the real dark sky (its 4:38pm but it looks like 6:45pm outside)


Monday night 56mm from previous forecast of 48mm with high tide at 11:52pm @ .82m
Tuesday night 59 mm previously 49mm with high tide at 12:37pm @ .79m
Thursday night 50mm with high tide at 3:05pm @ .52m
Friday night 36mm previously 86mm with high tide at 1:11am @ 1.10m
Saturday morning 59mm earlier at 72mm with high tide at 1:56am @ 1.17m
Saturday afternoon 59mm previously 68mm

Rainfall rate is generally described as light, moderate or heavy. Light rainfall is considered less than 0.10 inches of rain per hour. Moderate rainfall measures 0.10 to 0.30 inches of rain per hour. Heavy rainfall is more than 0.30 inches (7.62mm) of rain per hour.

Rainfall amount is described as the depth of water reaching the ground, typically in inches or millimeters (25.4 mm equals one inch). An inch of rain is exactly that, water that is one inch deep. One inch of rainfall equals 4.7 gallons of water per square yard.

Put more simply, every millimeter(mm) of rain means one liter of water in every square meter area. Thus if the prediction is 56mm of rain per hour with total of 300mm for the night, its roughly a foot of water... then if high tide coincides with the rush of water from the outpour... and you are in a path of cascading waters from the mountains... then another flood can be expected. While this is merely a prediction... No harm in being prepared!

During the rains yesterday, it flooded many areas of the city, one vehicle was reported to have been swiped by floodwater after it stalled at Acacia St Gordon Heights, 43 families were reported to have been evacuated and a landslide took place in Purok 12 Old Cabalan where two families were affected.
