Kochi: The Centre has informed that heavy rainfall events are showing an increasing trend over Kerala, and this has become more frequent in the last decade.
Replying to a question in Rajya Sabha, Union minister of state for science & technology and minister for earth sciences Jitendra Singh said there is an increase in the occurrence of heavy rainfall activity in Kerala during the southwest monsoon season (June to September) as per data for the period 2001-2021.
The number of events of heavy rainfall (more than 64.4 and less than 115.5mm), very heavy rainfall (more than 115.5 and less than 204.4mm), extremely heavy rainfall (more than 204.4mm) and heavy rainfall and above are on the rise during southwest monsoon season in recent years.
The IMD has plans to increase the network of automatic weather stations in Kerala. He said that Kerala is to have 115 weather stations. IMD planned for 100 automatic weather stations (AWS), and the earth sciences ministry recently installed 77 AWS, and the installation of the remaining 23 AWS is in progress.
In addition, Kerala has 15 more AWS stations, thus making a total number of 92 AWS available for Kerala. Apart from these, there are 10 upgraded automatic rainfall measuring stations in the state. IMD has already expedited the installation of sanctioned AWS for Kerala.
Meanwhile, southwest monsoon has been weak in the state for the last few days. IMD indicated that there will be isolated heavy rainfall in some places till Monday. Thunderstorm with lightning is very likely to occur at one or two places during this period.
The Met department issued a yellow alert for Wayanad and Kannur on Friday. Ernakulam, Idukki and Malappuram are on yellow alert on Sunday, while Kollam, Pathanamthitta, Alappuzha, Kottayam, Ernakulam and Idukki are likely to get isolated heavy rainfall of 7-11cm on Monday.
According to the 24-hour rainfall issued on Thursday morning, Neryamangalam recorded 7cm rainfall while Thodupuzha, Idukki and Parambikulam received 4cm each and Kanjirappally and Perumbavur received 3cm each.
The state has recorded a total deficiency of 25% from June 1-July 28. As such, July received good rains, which reduced the large deficiency of June by more than half.
Skymet weather said there is a likelihood of a freak weather system coming up over the southwest Bay of Bengal. A cyclonic circulation, starting from south-central Bay of Bengal may reach coastal parts of Tamil Nadu and Andhra Pradesh in the next couple of days. The system may not penetrate deep over land but may provide some showers to break the jinx of dry spell.
