Rough seas
High waves have been reported from various coasts in the state. Around fifteen houses in the Poovar and Pozhiyoor beaches near Thiruvananthapuram suffered damages. Residents were shifted o a relief camp at the Government school in Pozhiyoor.
Owing to the rough weather conditions, the Kerala government urged everyone to follow safety guidelines issued by the Kerala State Disaster Management Authority (KSDMA).
Under the influence of the low-pressure, the sea could be rough with strong waves and winds lashing the coast. Those living in regions prone to landslides and landslips, low-lying areas and river banks in districts for which orange or yellow alert has been issued should also exercise caution.
The windspeed is likely to go up to 60 kilometres per hour.
The India Meteorological Department (IMD) has advised fishermen not to venture into the sea from the Kerala and Lakshadweep coasts.
Meanwhile, summer showers, accompanied by lightning and thunder, have been continuing in the State since noon. People have been asked to adhere to the instructions issued by the KSDMA to safeguard themselves against lightning, thunder and strong winds.
The authority has warned people against venturing outdoors during lightning and thunder. They have been asked to remain indoors or in vehicles.
People living in natural calamity-hit areas in 2018, 2019 or 2020, and those residing in areas marked uninhabitable by the Geological Survey of India and KSDMA’s expert panel should make necessary arrangements in advance to meet any eventuality. Local self-government bodies and other government machinery in such places, too, should be prepared.
Considering the COVID-19 situation, the KSDMA has issued an Orange Book-2020, setting guidelines for preparing relief camps. Camps should be readied by adhering to the Orange Book.
Cyclone to move north-northwestwards
The Met Department said that heavy rainfall is likely at some places in Goa and south Konkan region.
"A low pressure area has formed over the southeast Arabian Sea and adjoining Lakshadweep. It is very likely to become well marked over Lakshadweep area by Friday morning," it said.
It will concentrate into a depression over the same region by Saturday morning and intensify into a cyclonic storm during the subsequent 24 hours, it said in the warning report.
According to the tropical cyclone naming system, the possible cyclonic storm would be named as cyclone Tauktae, a name suggested by Myanamar that means 'a highly vocal lizard gecko'.
It is very likely to reach Gujarat coast around May 18 evening, the IMD added.
Due to this, south Konkan and Goa region would receive light to moderate rainfall at many places on Saturday and its intensity would increase further and it would receive heavy to very heavy rainfall at a few places on Sunday and Monday.
According to the department, 64.5 mm to 115.5 mm rainfall in 24 hours is considered as heavy, while precipitation between 115.6 mm to 204.4 mm in 24 hours is termed as very heavy rainfall.
As the region is going to be affected by cyclone storm, the rains would be accompanied with gusty winds with a speed ranging from 50 kilometre per hours to 80 kmph in next 5-6 days.
