  1. What is this, ecmwf is completely playing with us, oh god please show some mercy, what forced ecmwf to change it forecast I don’t know, is it due to wd but wd is far high in latitude and also ecmwf expecting only our weaker system this is ridiculous

  7. Good morning. .

    The well marked low pressure area in the eastcentral Arabian sea is strengthening into Depression.Intensification chance is High. upper air circulation over bay of bengal off Andhra pradesh coast still persists.

    So rather heavy to heavy rain is expected in north interior Tamilnadu,western Tamilnadu,central interior Tamilnadu and parts of southern Tamilnadu in 24 hrs.

    Many places in north interior and western Interior Tamilnadu received heavy downpour yesterday.

    Parts of Chennai may receive light to medium rain today.Chennai is expected receive heavy rain after 9th nov.

  8. It seems that all regions of TN has got some ws rains except extreme northern dist.still now NEM has taken form of SWM

  9. Wow !!.. ECMWF merely reduce it to a low near tip of srilanka… Next update will show like a easterly wave I guess.. 3 day consistency of ECMWF is broken today..

  10. β€œA low pressure area is predicted to form on the Bay of Bengal coast around November 8 or November 9. This could intensify and lead to a wet Diwali,β€œ said Regional Meteorological Centre deputy director general S B Thampi.

    According to independent weather blogger Pradeep John, the sea temperature and wind shear is poised to form a system near the Andaman coast. β€œThe surface sea temperature is high at 30Β°C and it is being accompanied by low wind shear. According to numerical weather models, we are expecting a rapid intensification of a low pressure system that could bring plenty of rain to the city any time soon,β€œ John said.

  11. Real time tracking of such case studies will be even more interesting. I think this might be just another system to learn carefully.
