Rainfall in Tamil Nadu on 30.04.2020

West Tamil Nadu had got widespread rains in the last 4 days and the dry belts of Tiruppur, Coimbatore got much needed rains. The rains was particularly heavy in Nilgiris district in the Coonoor to Mettuapalayam stretch.  In the past 2 days, Tuty has been getting rains and these rains in South TN will continue till 8th November and then there will be a mini-break.

Reason for Rains

With UAC lying in Gulf of Mannar belt, it always gives plenty of rains to South TN and West TN, this one is not a strong UAC, but it created LWD in West TN with winds converging from west. While today monsoonish rains to Delta coast and South TN had started. The trend remains the same today and tomorrow too. So good rains can be expected in next 2-3 days for South Tamil Nadu. They have waited long for these rains. West Tamil Nadu will also continue to get rains in the next 2 days.

Today again South and West TN will be in focus

As we can see big ball of cloud in the convergence zone. The rains is spread inside as we go into the day. Thoothukudi, Sivagangai, Ramanathapuram, Pudukottai, Delta belt (partially), Virudhunagar, Kanyakumari, Thenkasi, Nellai, Theni, Dindigul, Coimbatore, Tiruppur, Nilgiris will all be in action. Delta will catch some rains too.

An UAC always favors the interiors more than the Coastal areas with LWD rains in the evenings.

Chennai and KTC

We got decent rains in the last 2 days and one more day we will have early morning rains. With an easterly wave from UAC, what we got is good numbers. People’s expectations have been too high demanding nature to pound with 100 mm rains always, it wont happen. Day time will be sunny as usual. Dont expect day time rains in NEM unless there is a low pressure or a Cyclone nearby.  The peak time for our rains will always be in late nights to early mornings, most of the time.

Coonoor – Mettupalayam belt Rocking

The locked belt of Nellithurai, Karamadai, Mettupalayam, Coonoor and Burliar are giants in North East Monsoon. Nellithurai in Coimbatore district has silently recorded 106 mm, 99 mm and 137 mm in last three days. Today numbers are awaited and expecting another great numbers in this belt.
