There is a general feeling in our blog that UAC wont give rains. All this myth is just because Chennai is not getting rains from UAC. The truth however is the opposite, Andhra is getting massive rains, many stations that too Coastal stations are reporting 100 mm rainfall without SW monsoon setting there and its due to the UAC. This is the 3rd UAC to from in BoB starting from May 2nd week and more UAC will form in coming week.
Chennai Rains: The Cyclone in Arabian sea is moving away westwards, this allows our BoB UAC to traverse down in the mid level and in coming days it is steered into Interior TN assuming that the UAC will be good shape but weakened in mid-level.
The UAC while moving down along the ridge creates wind confluence tomorrow night / 10th early morning. Though it is little north of us, i feel there will rains for Chennai too as there is abundant moisture not only at mid level but at lower levels too. That to me is always key to rains. The coming days 10 and 11 also looks good for rains with UAC moving into Interior TN. Lets start with 9th and then continue tracking.
