Another Active Rain-Day for South India while the Rest of India remain dry

The trough at lower levels from Interior Karnataka to Kerala continues to persist and will shift north to Maharashtra. This trough in conjunction with the Upper Air Circulation (UAC) in the Arabian Sea will continue to give rains to Karnataka, Goa, and Interior Maharashtra and also to the coastal areas of Kerala. Nedumangad (near Trivandrum) in Kerala has recorded a very heavy rainfall of 201 mm under its influence.

On the SE side, the twin UAC’s in the mid troposphere with one end near North Tamil Nadu with the other end in North-Central Bay of Bengal lies as an elongated trough. This, in association with the trough in the lower levels will bring heavy rainfall to north Tamil Nadu and Andhra Pradesh.
Chennai – Typical September day with very high humidity and thus high possibility of rains. Temperature will peak between 34 – 35 C.

Madurai – A cloudy and warm day with mercury ranging below normal at 34-35 C followed by rains later in the day.

Coimbatore – Will have a cloudy day with a chance of light showers. Temperature will settle between 32- 34 C.

  1. Congrats PJ!!!

    You were spot on with your forecasts yet again. You were always confident in the night we will get something even though radar wasn’t looking good. Few areas did receive drizzles.

  2. Gud morning guys after 7 days of no rain in my area . But today onwards chances are looking bright for chennai. Today entire chennai will be batterd . Lets keep hope ;).and now its drizzling in my area .

  3. Good morning guys. Expected rains atleast during the night. Nothing materialized. But things are changing fast. Good days for chennai and TN are on the cards.

  4. Gud morning… Today morning light rains occurred here around 5.15am.. lasted for 10mins & drizzles lasted for a hour..

  5. Surprise heavy rains in most parts of Interior karnataka in tungabhadra catchment areas and also very heavy rains in all the districts of Rayalaseema and Nellore prakasam Godavari Rangareddy Nalgonda mahaboobnagar districts..
    Intense cloud to ground lightening activity created menace in nellore prakasam Nalgonda krishna which killed more than 15 people.

    probably tungabhadra inflow gonna increase..
    Sunkesula dam in kurnool may receive heavy inflows due to overnight rains with 130 to 140 mm in catchment areas

  9. Guys let us get on with our own work…let us wait for nature to act rather we keep predicting second on second…i do not see any use…

  10. for me 25 SEP
    SA – 1 is starting and ending on OCT – 9
    the most ultimate and happiest thing for me is that i will have vacation from 10 to 28th
    so that’s The When NEM can Onset !!!!

  11. how come 20 people will die due to lightning alone in nellore? Was there no lightning arrestors in adequate number. The governments are complete useless these days. IN TN, lighting deaths are getting reduced due to many installations of lightning arrestors.

    • Intense lightening in krishna district killed 7 people…All were working in fields…
      Lightening shower burned nearly 10 people to death in nellore…Mostly causalities reported from villages

  12. Heavy inflow to sunkesula……dam gates to be opened soon…..water to be released to kurnool kadapa canal..
    Hope TB dam above sunkesula gets full….still its 75 percent full
    Thanks to the heavy rains in bellary west kurnool raichur koppal

    • pls share information for any inflow into dams related to telugu ganga porject because chennai city depends on its supply as you are also aware that all our four city reservoirs has gone bone dry

      • Still Tungabhadra is not full….if heavy rains continue srisailam can expect inflows..presently srisailam dried up….need to see heavy rains like this for ten days to improve the situation

      • This time elnino made entire krishna basin bone dry affecting lackhs of hectares of agricutural land

    • Amazing Typhoon Kilo on the right top may head towards Japan, and with JTWC’s numbered warning 70 going on..
      The track attached along, with official tracking of 18 to 19 days, this one may join the list of longer travelling storms in recorded history. Though it continues to track along the southern periphery of a deep subtropical ridge, it is exhibiting a robust poleward outflow…..
