Kochi: Though the state expected a repeat of Monday’s heavy downpour, rains played truant and gave the Kerala coast a near miss. The India Meteorological Department (IMD) withdrew the red and orange alerts sounded for the state on Tuesday morning. It was a bright and sunny day, though maximum temperatures remained well below normal in most districts. The highest maximum temperature recorded was 29 degrees C at Punalur, Thiruvananthapuram airport and Thiruvananthapuram city. Vellanikkara recorded the lowest minimum temperature of 20 degrees C.
For Wednesday, IMD has sounded an orange alert for Idukki and Malappuram indicating heavy rainfall of 11-20cm and yellow alert for Pathanamthitta, Kozhikode, Wayanad, Kannur and Kasaragod. These districts can expect rains of 7-11cm in some places.
Squally weather with wind speed reaching to a speed of 45-55kmph is likely to prevail over Kerala coast and fishermen are advised not to venture into the sea.
According to the weather department, the low-pressure area over central parts of Arabian Sea now lies as a well-marked low pressure area over the same region with the associated cyclonic circulation extending up to 4.5km above mean sea level. It is very likely to concentrate into a depression during next 48 hours and move further away from Kerala coast in a northwest direction.
Chalakudy received 15cm of rain and Ottapalam, 11cm on Tuesday. Enamackel and Kunnamkulam (Thrissur), Vadakara (Kozhikode) received 7cm of rainfall each. Peermade (Idukki), Ponnani (Malappuram) and Thalassery (Kannur) received 5cm of rainfall each.
According to atmospheric scientists, the strong Indian Ocean Dipole (IOD) as well as the Madden Julian Oscillation (MJO) are playing a role in enhancing the northeast monsoon rains over the southern peninsular region. MJO is a moving ‘pulse’ of cloud and rainfall that plays a role in tropical atmosphere and impacts seasonal variabilities. It is at present passing through the Indian Ocean. Hence, its impact will be seen until the end of October.
