  1. The city is likely to get heavy rainfall on Tuesday owing to a well-marked low pressure area over southeast Bay of Bengal, according to the Meteorological Department.

    Officials said the rainfall could be as heavy as 7 cm in some places of north costal Tamil Nadu, including Chennai and Puducherry. On Monday, several parts of the city, including Kilpauk, Villivakkam, Chetpet and T.Nagar experienced showers.Officials said that Nungambakkam observatory recorded 4.3 mm of rain while Meenambakkam registered 2.9 mm on Monday. The maximum temperature dropped by two degree Celsius less than the average of 33 degree Celsius.

  2. 8 30 a? lol… time s still to be 7

    Hehe..yeah..i was sleeepyy…n i put the normal time..but anyways its gonna be 8mm oly till 8.30 ere πŸ˜€

  3. OK – I am going to speculate here – its the weather after all πŸ˜› The system moved really fast and has shown consolidation in the last few hours. Now its hit land – this one is going to linger on for a couple of days.

  4. I think this is the first cloud mass to have bloomed n its reaching coast of TN now…..LP think is 1000km away…will have morwe of these cloud blooms in the next 2-3 days

    —————–
    THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.3N 89.4E IS NOW LOCATED NEAR 10.4N 89.0E, APPROXIMATELY 820 NAUTICAL MILES EAST-SOUTHEAST OF CHENNAI, INDIA. THE LATEST ANIMATED INFRARED IMAGERY SHOWS THE AREA HAS RAPIDLY ORGANIZED AND DEEPENED DURING THE PAST SIX HOURS AS SUPPORTED BY A ECENTLY FORMED CONVECTIVE BAND ON THE WESTERN FLANK. MULTISPECTRAL IMAGERY SHOWS A PARTIALLY EXPOSED, ALBEIT BETTER DEFINED LOW LEVEL CIRCULATION CENTER JUST EAST OF THE CONVECTION, THIS IS FURTHER SUPPORTED BY A 142005Z AMSU-B MICROWAVE IMAGE. UPPER LEVEL ANALYSIS CONTINUES TO SHOW 15-20 KNOTS OF EASTERLY VERTICAL WIND SHEAR HOWEVER A SLIGHT DIFFLUENT FLOW NORTHEAST OF THE SYSTEM HAS EMERGED. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS BASED ON A PGTW DVORAK INTENSTIY FIX AT 142330Z. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. IN VIEW OF THE COMBINED EFFECTS OF THE MORE DEFINED LOW-LEVEL CIRCULATION AND IMPROVED UPPER LEVEL CONDITIONS, THE POTENTIAL FOR

    THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
    HOURS IS UPGRADED TO FAIR.

    THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 10.4N 89.0E, IS NOW LOCATED NEAR 12.0N 86.4E, APPROXIMATELY 365 NM EAST OF CHENNAI, INDIA. THOUGH A WEAK LOW LEVEL CIRCULATION CENTER (LLCC) CAN BE VERIFIED IN A 151200Z TMI ICROWAVE IMAGE, THE ACCOMPANYING CONVECTION HAS SHALLOWED AND HAS ECOME LESS ORGANIZED. THE LLCC HAS MORE RECENTLY BECOME DIFFICULT TO LOCATE IN INFRARED IMAGERY. DRY AIR IS FILTERING INTO THE BASIN ALONG THE WESTERN PERIPHERY OF THE CIRCULATION AND IS LIKELY DAMPENING THE CONVECTION. AN UPPER-LEVEL RIDGE CENTER OVER THE NORTHERN BAY OF BENGAL IS RESTRICTING OUTFLOW AT THIS TIME. THE SYSTEM WILL HAVE TO SLOW FROM ITS CURRENT SPEED OF 15 KNOTS IF IT IS TO CONSOLIDATE BEFORE MAKING LANDFALL OVER INDIA. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB.

    THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
    WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO POOR.

  6. Going by the current intensity we can expect atleast 10 cm from this today.

    This system is not going to disappoint like Jal because it already pouring down

  7. K.N.

    If it’s 100 mm/hr then my target of 10cm for the day will be got in just one hour.

    Lets wait and see if the same intensity continues.

  8. Is ther any other system over SE BAY.? Some websites r sayin like tat…..now we r getting rain due to circulation over Sw bay ..am i right frnz?

  9. JTWC has in its recent updates traced a depression in bay at 11.8 North and 82.9 east approx.350 KMS south east of chennai. Imd is yet to announce the intensification.

    It looks like the system would bring heavy showers right from cuddalore to nellore coast for another 24 hours.

    let us hope for the best. always a depression or deep depression favourable to get good rains.

    ss.

  10. There is a possibility it would intensify and cross just south of chennai by tomorrow morning as a deep depression.

    if it maintains the same trend chennai would get not less than 25 to 35 centimeters of rain for another 24 hours from this noon.

    ss.

  11. One hour back, it rained very heavily in Mylapore and Mandaveli areas. Even good roads were inundated with water within a matter of 5 minutes.

  12. I think it will crossover the coast by tonight.

    Only the midday report by IMD will give us detailed info which will be known only by 2.00 pm.

  13. Cool Jon. For the first time, I got to see the downpour so heavily during this NEM season.

    Looks like the rains have finally decided to come to Chennai.

  14. 8.30 am started from chrompet with downpour -driving down upto Guindy with heavy rain with no visibility – Gundy to Nungambakkam no rains – Just entered office – it pouring in Nungambakkam now- Please recall my earlier prediction – Guaranteed – 500mm dificit mentioned by KEA – will be wiped out before Friday – JUST WATCH & ENJOY (: πŸ™‚

  15. very close to chennai coast both south, and north east heavy rains. still the city yet to be brought under heavy rain belt. could be possible soon.

    even kanchipuram no rains. hardly 30 to 40 kms radius some useful showers and of course towards south better rains.

    ss.

  16. The heavy section of the rains will continue till late evening or into diminutive hours of tomorrow. After wards as the system moves hinterland, rainfall will subside. I can see some wave patterns behind the system. That will give some intermediate rains. This system is going on my expected lines!

  17. Dhinakar,

    The rain has already subsided in Nungambakkam. Its just a few drizzles here and there.

    In the radar I do not see anything beyond 100-50 km. If something does not develop quickly. Rains will stop by 3. I hope I am proved wrong though.

  18. Kea.

    Your statement is absolutely right. one hour back it was so promising, but now it looks like only drizzling for chennai.

    in fact places beyond mahapalipuram nothing.

    hardly 50 Kms raidus there were some showers and now it reduced so much.

    we need to wait for some time to draw any conclusion.

    ss.

  19. the latest satellite picture taken at 11.30 is so much encouraging, as more than 2/3rd of clouds still open sea near to coast. IMD has not come out with any encouraging report.

    places outskirts of chennai have been receving contineous showers right from 8.30 AM but chennai is not that much benefitted.

    very strange.

    just 2 centimeters in 3hours nothing.

    ss.

  20. WU is predicting only 10 mm for today and 35 mm tomorrow.

    Foreca predicting 50 mm from 5 pm until tomorrow 5 pm

    Accu predicting 10 mm during the day and 20 tonight.

    So hopefully heavier spells hasn’t arrived yet

  21. @ssuresh – Let’s pray that IMD does not come out with anything encouraging….. πŸ™‚

    We have had several instances where if Ramanan & co says it will rain, it will be the most clear & sunny day. It is only when you don’t get anything from IMD does it rain in Chennai

  22. south of chennai between 50 KMS and 100 KMS towards sea has been receiving contineous rains right from 8.30 in the morning. i think it would spread little bit north and in that case possibly there could be heavy showers during evening. we have to cross at least 10 centimeters for 12 hours ending 5.30 PM today.

    ss.

  23. we have had at least three heavy down pours here in Adayar since 7:00 am, right now it is a steady drizzle…hope this continues πŸ™‚

    hope the govt does not declare holiday tomorrow, then it will stop raining 😦
