  3. Today is World Earth Day, Take the manthra of 3R- Reduce, Reuse, Recycle, Plant and preserve trees, one of the helping factor for Rains. Protect the environment ,Let us give this precious Earth to our future generations,cleaner and greener.

  4. Earth Day is an annual event, celebrated on April 22, on which day events worldwide are held to demonstrate support for environmental protection. It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network, and celebrated in more than 192 countries each year.

    In 1969 at a UNESCO Conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be celebrated on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature’s equipoise was later sanctioned in a Proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom Award in recognition of his work. While this April 22 Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues.

  5. Heat is building up steadily…dont get ur expctations high for the weekend rains…
    There is a long harsh summer coming up may -july….

  6. kea.metsite.com will not be working for some time. Some idiot dug up the road and all telephone lines got cut. Airtel Broadband not working due to this. Waiting for their person to fix it, lets see how quick they are.

  7. How many trees are cut down each day?

    Throughout the world, about 900 million trees are cut down annually, as of 2014. That equates to about 2.47 million trees cut down every day. These trees are used to make everything from lumber and paper to deodorant and food additives.

    • Is there any specific topic on weather in this or just epaper. If just epaper almost all News Papers have epaper

      • Wanting to know whether the link Dinamalar epaper – provided by you has any information on weather – or just you have provided a link for information purpose.. When I opened it I could see only an article on Chidambaram Temple.

  9. with scorching summer poking it’s nose nearby, and with models prediction about S.W.M for T.N not healthy, at least this time Chennai should get widespread good rainfall, all over Chennai and suburbs,

  10. Indian Weatherman @weatherofindia · 11h11 hours ago
    HEAVY T showers also expected for #chennai, S,S-E Karnataka, #Bangalore and S Andhra on evening, midnight of Friday and early hrs of 25-Apr.

  11. RT @manoramaonline: Heavy rain in #Kerala, three die of lightning in #Thiruvananthapuram

    Thiruvananthapuram: Three men died here after they were struck by lightning on Tuesday, a day that saw parts of Kerala receiving heavy rain.

    The deceased have been identified as Jagan from Kunnukuzhy and Freddy and Michael, both hailing from Poovar.

    Thampanoor has been inundated following heavy rain which started in the afternoon. The Thiruvananthapuram District Collector has issued a warning to the residents.

    Travel to hilly regions, including Ponmudy, has been restricted. People residing at lowlands have been asked to keep a strict vigil.

    The Collector ordered district, taluk and village-level officials to return to respective offices.

    Heavy rain continues to lash various districts in the state.

    According to MeT office, heavy rains were also reported from Alappuzha, Punalur and Kottayam areas.

    An air current formed in the skies of Lakshadweep is said to be the reason for the rain. The unexpected rain caused huge traffic gridlock in Ernakulam. The Meteorological Department said that heavy to moderate rains would continue for two-three more days.

  12. On Friday & Saturday (24 & 25-Apr) an upper-level N-S trough from E-central India to S-E Tamilnadu is expected .. http://ow.ly/i/asR2W
    On Friday, the LWD is expected from S Tamilnadu to N Tamilnadu into S Andhra and to N-E Karnataka … http://ow.ly/i/asRVD
    This LWD on friday is expected to push in moisture thru S-E from Bay.
    The upper-level trough and LWD can pop heavy T showers for N Tamilnadu

    As of latest GFS..
    HEAVY widespread rain for N,central,N-coast,central-coast Tamilnadu on evening, midnight of 24-Apr http://ow.ly/i/asShP
    HEAVY T showers also expected for #chennai, S,S-E Karnataka, #Bangalore and S Andhra on evening, midnight of Friday and early hrs of 25-Apr.

  13. Latest GFS reduced intensity, not to be worried.

    24th Rainfall Intensity reduced in Chennai as per latest GFS, also that intensity shifted to South AP and
    West of Chennai.

    Chennai will get rainfall overnight or early morning on 25th with lesser than expected by us.

  14. The upper air cyclonic circulation over Lakshadweep area and neighbourhood persists and now extends upto 3.1 km above
    mean sea level. A low pressure area may form over the region during next 24 hours. Imd Delhi Midday report

  15. i remember this model never picked up before 2 days…looks like weather over southern india especially for TN is very dynamic and challenging..

  16. Below normal rainfall predicted for 2015 S.W.M by IMd intial report, 93% of Normal rainfall predicted, Sky met stands in its report of Normal rain fall

  17. The rains will be 93% of the 50-year average. Probability of deficient monsoon is 33%, probability of normal monsoon is 28% and the probability of above normal monsoon is negligible. Imd monsoon forecast

  18. kerala rain:

    trivandrum city 160
    tvc ap 144
    kollam 125
    kottayam 156
    nadumangad 109
    kayamkulam 131
    kurudamannil 146
    mancompu 123
    mavellikara103 in mm

    are som of the highlights

  19. The moisture spewed by the outgoing low is descending in the south in.Kar And north in.Tn causing thunder cell activities

  20. Its bad luck in the absence of WD, the present CC moving away from Indian peninsula. Our next hope will be at SE-BOB. Lets shift the focus on cloud build up over that area.

  21. Summer gripping Telangana and Rayalaseema
    Temperatures at 3 pm
    Singareni manuguru coal belt 44.9 degrees
    Medak 42.9
    kadapa 42.6

    kurnool 41.4
    Hyderabad shamshaabad airport 40

  22. At the same time heavy rains in visakhapatnam and district

    Started Raining with thunders in hyderabad also

  23. The outer bands of LPA/trough of LPA pumping moisture into Kerala, Karnataka and interior Telangana. This moisture pumping may ignite local convective TS activity in those areas.

  24. MJO and trade winds weakened. and there is no WD too for the necessary moisture. so no major things will happen during next 2-3 days except some isolated convectional TS activity over Kerala, TN, isolated places of Karnataka, Telangana & AP states.

  25. not going to make much difference , all models are on target..so expect 120-140mm from friday-sunday..

  26. Excellent rains around Bangalore… But still nothing is there for Bangalore… Thanks to the out moving low near lakshdweep..

  27. High Intensity Rains lash Trivandrum and Kerala, ending 8.30 am on 22.04.2015
    The cyclonic circulation over Lakshadweep-Maldives area now lies over Lakshadweep and neighbourhood and extends upto 3.1 kms a.s.l. A Low pressure area may form over the same region during next 24 hours.

  32. Crisil worries on weak monsoon prediction


    The bleak monsoon forecast by the Indian Meteorological Department has the potential to shave off 0.5 per cent of the GDP forecast of 7.9 per cent of fiscal 2016, said Crisil in a report.

    A second straight year of weak monsoon will decrease the efficacy of irrigation ecosystem and hit agricultural output and farmers adversely. In addition, unseasonal rains since early March have already had a negative impact on many crops, it added.

    Given weak investment climate, tepid export growth and fragile consumption, a normal monsoon is crucial to push economic growth this year, it said.

    Without predicting the effect of El Niño, IMD on Wednesday said the monsoon to be at 93 per cent of the long period average with a margin of error of five per cent on either side.

    If El Niño indeed plays out, it will be for the second straight year. It impacts spatial distribution of rainfall, causing floods in some parts and drought in others. And this time, the impact on agricultural output will be greater compared with last year, said Crisil.
    “Our base case, given a normal monsoon, is that agricultural growth will be 3% — up from a weak base of 1.1% in fiscal 2015,” it said.

  33. models are always like that…dont worry some activity is there..last week spell was also like this. so models have promised much lets see…i am sure we will get atleast 4 cms.. Meenambakkam 105 mm last week rain anything to add will be real bonus

  34. IMD predicts second consecutive sub-normal monsoon


    The India Meteorological Department’s (IMD) first outlook for this year’s southwest monsoon (June -September) released here on Wednesday raised the prospect of a second-straight sub-normal monsoon which could impact agricultural output.

    The Met department predicted that rainfall could be 93 per cent (subject to an error margin of plus/minus 5 per cent) of the Long Period Average (LPA). It classifies rainfall between 96 and 104 per cent of the 50-year average of 89 cm. as normal.

    Actual rainfall last year was 88 per cent of the LPA, the lowest in almost 30 years. The four-month-long monsoon accounts for 70 to 75 per cent of the country’s annual rainfall.

    Under the five category probability forecast, which indicates the chances of good or poor rainfall, the IMD has predicted that there is a 28 per cent probability of normal rainfall while there is a 68 per cent of a poor spell (33 per cent probability of deficient rainfall and 35 per cent chances of below normal rain).

    “The onset of the southwest monsoon will be announced on May 15, we will have a clearer idea of distribution in time for the June forecast,” said LS Rathore, Director General of Meteorology, IMD.

    Parts of northwest and central India are likely to be affected by the shortfall in seasonal rain.

    El Nino concern

    The El Nino condition is caused by prolonged warming of equatorial Pacific Ocean surface waters and occurs at irregular intervals of two to seven years. In India, it had affected rainfall patterns and caused two severe monsoon failures in 2002 and 2009.

    “El Nino has been factored into this forecast but there are other parameters. Of the 14 years in the past when we had El Nino, eight years had bad monsoons,” said Rathore.

    Several international Met agencies have forecast a 70 per cent probability of an El Nino event in 2015. Harsh Vardhan, the Earth Sciences Minister, said that conditions were being monitored while “the Prime Minister’s Office and Cabinet Secretariat have also been informed to be prepared”.

    “Currently, weak El Nino conditions are prevailing over the Pacific. The latest forecast from the IMD-IITM coupled model forecast indicates El Nino conditions are likely to persist during the southwest monsoon season,” the IMD noted in a statement.

    Worrisome picture

    Analysts expressed concerns about the possibility of a poor monsoon on crop production and the wider economy particularly since it will come in the aftermath of unseasonal rainfall and hailstorms between end-February and early-April.

    The western disturbances, which Rathore said will not have a bearing on the southwest monsoon, caused significant damage to key Rabi season crops like wheat and mustard as also vegetables and fruits over some 10 million hectares across north, west and central India.

    “Unseasonal rains since early March have already had a negative impact…a deficient monsoon, if it comes true, will shave 50 basis points (0.5 per cent) from our GDP forecast of 7.9 per cent,” stated a Crisil research report.

    Given a normal monsoon, agricultural growth should touch 3 per cent, up from 1.1 per cent in 2014-15.http://www.thehindubusinessline.com/industry-and-economy/agri-biz/imd-forecasts-below-normal-monsoon-rains-this-year/article7129984.ece?homepage=true

  35. One truth about the Numerical Weather Prediction(NWP) models i.e., almost all our models that we see in day to day output has the greatest difficulties while inputting certain parameters. Tropical Convection is one among those parameters. The way the atmospheric flow changes would take place can nowadays be predicted with decent accuracy , but the time, location and intensity predictions of Tropical convection remains one tough stuff to deal with ……..

  36. After a break Karnataka joins the party, Rainfall ending 8.30 am on 22.04.2015
    The cyclonic circulation over Lakshadweep-Maldives area now lies over Lakshadweep and neighbourhood and extends upto 3.1 kms a.s.l. A Low pressure area may form over the same region during next 24 hours. Over 200 stations have reported rainfall, hence cut-off is kept at 35 mm.
