Heavy rain and a Break !

For yesterday (22-Oct-08) morning till 10:30 AM it was raining heavy, some times very heavy.
T.Nagar and other parts are partly flooded.
At around 10:40 sun came out bright and it had signs of clearing.
But after 11:30 AM the sky became gloomy and heavy, then it started drizzling heavy and it stopped at around 4:30 PM.
After that drizzle the low level air current changed direction to North-West.
Please note: Once the air-current changes to North-west all the rain activity will reduce to ZERO.

Now (23-Oct-08, 2:15 PM), till now the wind is in North-West-North.
So no sign of Rain yet...!
Look at the latest satellite pic...

we can see two formations, one near "Kerala" and another near "Andhra".
And another likelyhood is VERY near to North-Tamilnadu.
Overall, there was heavy rains thru out Tamilnadu.

  1. The European Center for Medium range weather forecast says that a low pressure is likely to form in the west central and adjoining northwest Bay of bengal.so says the IMD forecast too.which means rains to andhra and orissa and may be west bengal coast.Tamilnadu might not benefit much.It predicts that it may be a depression which might move northwest and make landfall in the orissa coast. I hate this stuff.. for the NE monsoon is meant for southern states and the NE monsoon is highly unpredictable unlike the southwest monsoon.Also its quite important that we receive a good amount of rain in October ( Early NE monsoon season ).Once November approaches low pressures and depressions slacken.. Atleast that has been the trend in the past few years.
    Wish a depression forms in the bay and moves west north west towards TN coast.
    No starying North please :)

  3. Forecasts based on the movement of the periodical Madden-Julian Oscillation (MJO) wave of alternating enhanced and suppressed phases of rainfall suggest that the ongoing wet session over the southern peninsula would weaken towards the month-end. This is based on the assessment that the current phase of the MJO wave, travelling periodically from West Africa into Indian Ocean and further east into the equatorial Pacific and beyond, would be followed up by the suppressed phase from November 1.

    This weakened rain phase would last until November 22, according to the ensemble forecast system of the US National Weather Services. The successor MJO phase of enhanced rains is expected to get anchored over equatorial Indian Ocean and the southern Indian peninsula from December 2.

    A long-term outlook by the UK Met Office and the European Centre for Medium-Range Weather Forecasts suggested ‘above normal’ rain for southern peninsula through December, January and even early into February.
