Rains to decrease in Tamil Nadu

With no significant system in action and the monsoon axis sticking to Himalayas with extension to north east, Monsoon will take a small break. Meanwhile, the Upper Air Circulation (UAC) over Bangladesh looks weakened. However, a North-South trough dips down from this UAC into North Bay of Bengal and this will bring rains to Jharkhand and Odisha. Rains will also continue in parts of North East India. The Western Disturbance (WD) over Pakistan will give rains to Himachal, Uttarakhand,Kashmir and also along the foot hills of the Himalayas.

Tamil Nadu has been reveling in the much needed rains for the last 4 days. The drought hit Vellore district has smartly moved from deficient to above normal category.However, there will be decrease in rains in the state of Tamil Nadu as the influence of UAC fades away in the State.


Chennai – Cloudy day with temperature to peak around 34-35 C. Rains are expected in isolated parts of the city and suburbs.

Coimbatore – Dry day on the cards with temperature continuing in the range of 31-32 C.

Madurai – It will be a partly cloudy day with max temperature range bound at 34-35 C. There is less chance for rains in the city.

  12. Chance to Have Bird’s View of Marina

    If you thought that the Marina Beach was getting boring, think again. Chennai’s premier beach, on Saturday, got itself its first parasailing attraction with Indian Aero Sports and Science offering the aero sport to thousands of tourists and Chennaiites who throng the Marina’s sands.

    Indian Aero Sports and Science conducted training camps for the police’s Coastal Security Group last month and has been thinking of offering parasailing to the general public for some time. Implementing the facilities and obtaining permission took a while.

    “We had a lot of testing to do before we could get it in place. But now that we have, we will operate everyday from 10 am to 6 pm as long as the weather is favourable,” said T Babu, Director of Indian Aero Sports and Science. The attraction also comes incredibly cheap, compared to similar ones present on the beaches of Goa and a few other coastal cities. The rate per person has been fixed at Rs 300 for school and college students and Rs 500 for others.

  14. Waterfalls Lakes Plitvice, Croatia (National Park)
    Is among the 20 most beautiful lakes in the world to 17th place. The park covers an area of 33,000 hectares and includes 16 lakes in succession, connected by waterfalls.Plitvice is the oldest national park in Southeast Europa.All’interno the park there are also many caves of which only a small part is agibile.I lakes are formed by two rivers: the White River and the Black River, which flow in the river Korana. The waters of these rivers are rich in calcareous salts (mostly calcium carbonate and magnesium carbonate), from the dissolution of carbonate rocks forming the geological structure of sito.Questi salts are precipitated by vegetation, forming layers of travertine , a sedimentary rock recently. Over time, these deposits forming real natural dams that act as barriers to water, growing by about a centimeter per year. At one point the water pressure breaks these natural levees, opening new paths in the ground.
    This mechanism, in fact common to all the calcareous water, in Plitvice has assumed a particular importance.
