At the end of SW monsoon - 08

We (Chennai) is at the end of SW monsoon.
Now it's clear skies with patchy clouds around and humid days and mild nights.

Still there is low level SW air current. And no sign of North-easter yet.
Hoping to see the North-East monsoon around 10th to 15th of October.
Usually north-east sets in around 15th in North tamilnadu and around 22nd in south tamilnadu.

This year's north-east will also be a long one, like that of Last year - 2007.

Our next post will be a summary of South-west - 2008.

For another 10 days the weather will be like this after that we can see the signs of Northeast monsoon.
I'm expecting a MORE than NORMAL north-east monsoon.
It might start at around 10-Oct-2008.
