There are slim chances of the revival of south- west monsoon with the state recording 43 percent deficient rainfall by the beginning of August. During June-July, the first and important months of monsoon period, the state received only 81.07 cm against the long-period average of 141.88 cm.
All the districts present a poor show and Wayanad tops the list with a 68 percent deficiency.
The India Meteorological Department (IMD) is pinning hopes on a low pressure expected to develop over north-west Bay of Bengal around Saturday. ‘’A fresh spell is expected around Saturday as a low pressure formation is likely to develop near the West Bengal coast,’’ said K Santhosh, director, IMD.
The district-wise percentage departure from normal rainfall are as follows: Pathanamtitta (-59), Thiruvananthapuram and Alappuzha (-57), Kollam (-56), Kottayam (-45), Ernakulam (-43), Malappuram (-38), Thrissur and Idukki (-37), Palakkad and Kannur (-36), Kasargod (-33) and Kozhikode (-29).
The period of June to September is considered as the monsoon season. In this four-month period, the highest amount of rainfall is usually reported in the first two months. A dismal performance of monsoon during June and July will have much impact on the agriculture and power sector of the state. A developing El Nino condition during September too is expected to be a monsoon dampener.
The IMD update on Thursday stated that the feeble off-shore trough from Karnataka coast to Kerala coast has become less marked. This indicates decreased rainfall activity over the peninsular region.
