A day after Skymet, a private webcaster, predicted that South west monsoon will hit the Kerala coast on June 4, the Indian Meteorological Department has said the monsoon showers will arrive in Kerala only on June 6.
While announcing this, the Met department said that that they used an indigenously developed model for predicting the onset of monsoon from 2005 onwards. It said that they used six predicators such as minimum temperatures over North West India, Lower tropospheric zonal wind over the southeastern side of Indian ocean, pre-monsoon rain over southern Peninsula, upper tropospheric zonal wind over east equatorial Indian Ocean, Outgoing Long Wave Radiation over South China Sea and OLWR over south-west Pacific region.
The IMD also claimed that its predictions from 2005 were all correct expect for the year 2015.
The Met department also said that conditions are favourable for the advancement of monsoon over Andaman and Nicobar Islands. Normally the monsoon hits Kerala coast ten days after it reaches the Andamans.
The Skymet had on Tuesday predicted that the Monsoon will reach Kerala on June 4 and that the monsoon this time will be below normal. The first showers of South West Monsoon normally hits the country on June 1.
