As the countdown to the launch of the North-East monsoon progresses, piloting rains are forecast to grow over the southern peninsular India during the next two days.
An India Meteorological Department (IMD) outlook suggested that the nuisance value of the weakened ‘low' over Myanmar and Bangladesh may have been eliminated for winds to settle into a pattern ideal for the North-East monsoon regime.
