A cousin sent me this photo:

Chennai gets 1400 mm average rainfall for the whole year: about 100 mm in the first 5 months of the year, 400mm from Jun to Sep and 900mm from Oct to Dec. 1:4:9.

4. http://www.kea.metsite.com/: streaming weather data showing temperature, pressure, rainfall, wind etc. for Chennai. An issue I find in the site is this: "Rain rate: 16.0 mm/hr      Hourly: 26.2 mm": from the site. What is this data supposed to mean? I suppose hourly refers to rainfall in last 1 hour while rain rate is the differential current d(rain)/d(time).

A friend sent me this (it's in Tamil) which provides an astrological explanation of events.
