BB-10, is now a Well Marked Low Pressure, at 1004 mb. Located in Interior Karnatak near Davangere.
The wind speed in the E, SE and NE of the system is still at almost 25 knots. So winds in the Southerly direction are pushing North along the North TN coast. This has resulted in good precipitative clouding in the East and more in the NE quadrant of the weakening system. So, the rains in Vidarbha and adjoining Karnataka and AP are due to the BB-10 system.
Now, our East-West trough runs along the 15N line, and extends upto the 850 hpa level. With the BB-10 embedded in it. Sustaining power depends on BB-10.
Mumbai winds prevailing at E/NE till afternoon...
