More Rain expected due to Trough & UAC

Rainfall occurred at many places over coastal Tamil Nadu including Chennai city. The upper air trough in the easterlies from South-West to West- Central Bay of Bengal extending upto 2.1 KM above sea level persists. The upper air circulation over Sri Lanka & Adjoining Comorin area extending upto 4.5 KM above mean sea level also persists. This would bring tropical downpours at most places over Kerala and many places over Coastal Tamil Nadu, parts of Interior & South Tamil Nadu and Puducherry. Chennai city will be welcomed with early morning showers and few scattered spells during the day.
A western disturbance would affect eastern Himalayan region from 2nd November onwards.
Rain would occur at few places over coastal Andhra Pradesh, Coastal Karnataka, Telangana & Rayalaseema, Sub-Himalayan West Bengal, Arunachal Pradesh, Sikkim, Bihar, Gangetic West Bengal and Odisha. Dry weather would prevail over rest of the country.

Chennai – Early morning showers and few spells of rain in day time over many parts of city with Max Temp of 32c
Vellore – Fair and cloudy weather with a thunderstorm in the afternoon. Max temperature may touch 32c
Madurai – Mostly cloudy conditions will prevail. Max temperature may touch 32c
Trichy – Light fog in the morning. Thundershower possible in day/evening. Max Temperature would be around 32c
Coimbatore – Thundershower possible in the evening over parts of city. Mercury may touch 33c

North East Monsoon
The Great Bhola cyclone remains the deadliest tropical cyclone ever recorded and one of the deadliest natural disasters in modern times. Nearly 500,000 people lost their lives in the storm, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. The cyclone formed over the central Bay of Bengal on 8th November ,1970 and traveled north, intensifying as it did so. It reached its peak with winds of 185 km/h (115 mph) on November 11, and made landfall on the coast of Bangladesh the following afternoon.

  1. clear blue sky with bright / sunny weather. clothes drying up. no more rains it seems. we need strong popups with in 30 KMS radius east & north east. nothing is visibel as of now. we have to look out for evening thundershowers due to heat, humidity, moisture & wind. this is a different climate during NEM. no scope for any system also for the day.


  2. Beautiful Chapala……….instead of originating in Arabian Sea..if it was originated in Andaman KEA blog would have made news again

      • No this period of time generally cyclones move straight…like neelam which affected us on same day… Novembe 1st

      • Depends on the intensity and area of genesis. Chapala was cat 4/5… if it was in bay it would have easily broken any ridge and moved north towards NAP/Orissa. Additionally, in the northern hemisphere, due to earth’s rotation the cyclones tend to get deflected north west.

  3. about 60 KMS south east, east, north east a squall line is forming. all can merge and move towards ctiy. yesterday it was similar connditon at 10 AM. now these squall will strenghten and move towards city after two hours. we can expect some thing around 12.30 let us hope for the best. the bright sunny weather infact is good for good spell to follow.

  4. squall in sea around 60 KMS moves in which direction. it has to merge, flank and move to get some rains to cityby noon. any opinion on this. please see radar.


  5. there is no proper direction of winds like yesterday. the sea squall is devellping, flanking might move towards city afternoon. we have to wait for some more time to assess the condition. but squall line is growing big. in sea.


    • I guess It always happens every year..the diff is nowadays we r noting everything and polambifying..its part of the game..atleast Vizag is benefitting,rt..also we will also get decent rains

  6. Intensity is too low considering the warm waters & the mjo presence in eastern indian ocean.. Watchout this may turn into monster if it falls sw of the UTR…

  7. 1982 Chennai cyclone has similar type forward loop in MJO within phase 2 (with amplitude less than 1). This time it’s making loop in phase 2 with higher amplitude (>1). So it will be sure shot of “Named cyclone”.

  8. If it becomes direct chennai cyclone, then need to assume my earlier 1982-Chennai cyclone gets little bit delayed 😆👍

  9. a massive squall approaching city from south, south east and east. a strange direction. but this is due UAC and trough just norht of chennai. we will get useful showers in 20 mts.


  10. மேகம் கருக்குது இடி இடிக்குது மழை ஆரம்பிக்குது – Dark clouds , thunder and light rain and in a short while action packed movie
