After the revival of the southwest monsoon for over a week in September, the intensity of rain is set to come down in the State.
Kerala witnessed an average of 136 mm of rainfall in the first nine days of September. August had registered a monthly rainfall of only 59.6 mm, the lowest monsoon precipitation in 123 years in Kerala.
The late surge was aided by a low pressure area over the Bay of Bengal and the subsequent shifting of the monsoon trough — an elongated low pressure zone from the heat low of northwest India with its axis running parallel to the Himalayan mountains in a west-to-east direction — southwards of its normal position.
