  2. If the storm forms to the east of the city, then the rain window is going to be short ?? like what happened in the case of Laila ?

  3. i dont think it might be laila ..laila is a very rapid moving storm but this one looks to be a slow moving one so the possibility of prolonged rain is more..moreover laila is cat 1 so LLC is pretty compact but the computer models forecast this developing low to reach around 998 mb which is not a compact one so the clouds will be preety disorganised even it is a bit far away we will get good rain due to less organised structure of the storm.For all this to happen let the depression form first :)..only if it forms we can compare it with laila.

  7. Is it apt to brand the rainfall we receive as south west Monsoon rains ??
    Low pressures/depressions can bring rainfall at any time of the year irrespective of whether there is monsoon or not.
    If the city receives rains without low pressures /depressions and if it is because of moist south westerlies we can call them monsoon rains.

    The North east monsoon is indeed called monsoon for chennai as rain bearing winds blow directly over the city and produce rains even without a LP or depression

    I wonder why weather reports sometimes say ‘Southwest monsoon vigorous over Coastal TN’
    Does it really fit the bill ?

  9. @jon
    u r gr8!!!!!!!! 😎 bcause u told that it would start raining heavily near 1330 hrs ist and its raining here very heavily!!!!!!!! 😀

  10. im from valasaravakkam close to chandrus house!!!!!! 🙂 rains continue ere!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 😀

  11. Omg..Check out BBC’s forecast for chennai on Wednesday night.. It shows a massive green area over chennai indicating very heavy rains

  12. Under the influence of the upper air cyclonic circulation extending upto 2.1 km above
    mean sea level over west central and adjoining south west Bay of Bengal, a low
    pressure area would develop over the same area during next 24 hours.

  13. shear is starting to increase again.The system has to fight all these verticle shear to organise.Still there is no surface low visible.

  14. hey wind shear is increasing this is a big minus point for the formation of low pressure,hey vinodh can u tell me whether any chance of low pressure along andhra tamilnadu coasts?hey its quite cool and cool breeze in vijayawada but shockingly scorching sun,scorching sun is responsible for above 30 degrees temperatures along andhra coast,so vinodh pls tell me any chance of rains for vijayawada or any chance of formation of depression?

  15. @shyam even i am trying to find a link where we can find future vertical shear value in bay.i could not find a one..The cmiss website is showing only the current shear values and its tendency not the future values.

  16. @radhakrishna increasing vertical shear is a storm killer..BBC and certain models are still mintaining a possible depression making landfall near machilipatinam if that is the case vijayawada willl be getting heavy rainfall from tuesday..There is not even a single website where it is showing the future shear values..so we must go by the info given by weather models only..BBC is predicting very heavy rain for the north TN and south AP coast..even if we dont have any organised sytem we will be having a good rainstorm system

  17. if models predict a depression then definitely the shear are gettiing reduced but till now the shear have not decreased maybe it will decrease in future but if the shear continues the same status then there is no chance of any organised sytem.

  18. and vinodh what are your ideas about depression near vietnam mwhich is moving west to merge into bay of bengal and turn out again into a depression that may strike andhra or tamilnadu coasts?this is happened especially for andhra in many cases and for example typhoon gay which merged in bay of bengal from south china sea and then made landfall near machilipatnam with peak intensity to knw abt typhoon gay clicl the below link
    http://en.wikipedia.org/wiki/Typhoon_Gay_(1989)

  19. Radha, That storm tracked in that direction may be because it was the prime North east monsoon season.. Usually we dont see such systems coming over from South china see and intensifying in Bay of Bengal during the south west monsoon period

  20. in last 11 years chennai has never got more than 100 mm per month 5 times in a row. Will 2010 be different.

    May – 204, June – 137, July – 158 and August 153 and counting.
    2010 can also break the most months with 100 plus days. Currently 2008 stands top at 6.

  21. @radhakrishnan depression 06W tracking in a north westerly direction and expected to make landfall close to hanoi.since it is moving in a northwesterly direction the distance between the bay of bengal and the storm is getting drastically increased.It is diffcult for LLC to maintain the intensity for a longer period of time over the land

  22. @Jon…non-stop rains from pdc to tambaram..the rain eased of a bit near vandalur..but picked up in tbm..interestingly cld mvnt was east…but low cloud mvmnt was from west nw…very very low clouds..that it covered up small hills near chengalpet..ive captured soem awesome pics 🙂 …superb rains 🙂

  23. In the Indianwweatherman blog site, Rajesh says that a western disturbance entering north India could steer the low towards Orissa or W.B coast and that rains in TN will decrease in the next 3 days ??

  24. chandru,

    thats xactly what BBC predicted. If it takes that route chennai will get a battering over the next 3 days. Minimum of 100-120 mm

  25. is there any chance of rain again??? it looks like clouds have cleared up… pls let me know …. iam not experts like you..plsss
