Thiruvananthapuram: Weather conditions are becoming favourable for the onset of southwest monsoon over Kerala around June 5, an India Meteorological Department (IMD) said on Tuesday.
The IMD’s bulletin forecast heavy rainfall at isolated places in Kerala and the Lakshadweep from June 5 morning till the morning of June 6.
The IMD earlier forecast the southwest monsoon would set over Kerala on May 30, with a model error of plus or minus four days. If one were to go by this calculation, June 3 would be the last date for the onset of monsoon in the southern state.
Meanwhile, scattered rain was reported on Tuesday at a few places in the state, but most parts of the capital district and other places in Kerala witnessed a rise in day temperature, as the sun shone brightly. With high humidity levels, this made the day difficult for people.
In the past three years, monsoon set in in the first week of June, while from 2006 till 2011, the onset was in the last week of May.
Weather officials are analysing the data recorded at 14 weather stations located at the Lakshadweep, Kerala and Mangalore in Karnataka.
The onset of monsoon is declared on the basis of amount of rain received at these 14 stations. Besides, wind and cloud formations are other indicators.
