Weather experts have predicted that the south-west monsoon will slowly withdraw after the heavy rains and floods in Kerala since the rain was excess than the normal and as the monsoon already withdrew from the northern states.
But the recent Indian meteorological department report had issued another red alert for 3 districts of Kerala from 7th of October, the report says that a low-pressure area is likely to form over the southeast Arabian Sea and adjoining Lakshadweep area around 06 October 2018.
It is likely to concentrate into a depression during the subsequent two days and move northwestwards which will give very heavy showers for Kerala and hence asked the fishermen not to venture into the sea, IMD also asks the fishermen to reach the shore immediately as the thunderstorms could occur in the mid sea as well.
Meanwhile, this has impacted the neighboring state Tamil Nadu as well. Heavy rains are lashing the central/north districts of Tamil Nadu and district administration of Tiruvarur, Salem, Nagapattinam, Pudukottai and Cuddalor districts have announced the closure of schools on Friday and Puducherry government also announced the closure of schools because of heavy rains. Moderate rains and thunderstorm is been forecasted for northern parts of Tamil Nadu including the state capital Chennai, Kancheepuram and Thiruvallur districts.
Moderate rains are already on in isolated places of both the states and in the western ghats already. The report from the IMD also has forecasted another low-pressure area over south-west Bay of Bengal sea in next four days which could possibly develop and turn into a depression or cyclone when further intensifies. However, the red alert will not affect all the districts of Tamil Nadu, the exact districts which are under red alert will be notified by the IMD after seeing the wind pattern and other parameters of the low pressure.
This is a rare phenomenon where a low-pressure area is witnessed in both Arabian sea & Bay of Bengal and a transition from the south-west monsoon to northeast monsoon. Its also been predicted that south-west monsoon will slowly withdraw after this and northeast monsoon will intensify after this.
Meanwhile, the IMD had also warned the state authorities to take precautionary steps to avoid any untoward situation and the state officials of both Kerala and Tamil Nadu have already initiated the works according to the recent reports.
