Upper air circulation & 'MINDULLE"

What you see in this left is an extended aviation chart for Flight level 050 [5000 ft]. It clearly shows circulation at 850 hPa level in WC Bay and Adjoining SW bay i.e say between Chennai and Machilipattinam and it extends upto Head Bay. [But a separate LOW near head bay is also depicted.]

It will bring rainfall in North Coastal Tamilnadu, Coastal AP, Orissa etc in next one day or two.

The other chart depicts the formation of Tropical Storm 'MINDULLE'. [16.7 Deg North / 109.2 Deg East] It is moving in WNW direction. When it reaches Indian latitude it may influence the system in the Head Bay. We will wait and see.
