The progress of the southwest monsoon,according to the Indian meteorological department (IMD),is as per schedule. As of Monday,the monsoon has covered the entire Andaman islands.
Dr S Pai,senior scientist at IMD,said the monsoon had moved over some parts of the southeast Bay of Bengal and some parts of east central Bay of Bengal. The progress of the monsoon is normal and we have seen good cloud formation over Kerala too, he said. IMD has predicted that the monsoon would hit the Kerala coast on June 3.
There are three major indications for the setting of the monsoon in Kerala,and we are keeping a very close watch on them, said Pai. IMD has identified 40 weather stations in Kerala,and the rainfall data recorded there is used to declare the arrival of monsoon. If 60 per cent of the stations report rainfall over 2.5 mm for two consecutive days,the IMD declares the arrival of monsoon, he said.
Other than that,the speed of westerlies (the rain carrying winds) is also observed and also the cloud cover over the skies are taken into account to declare the arrival of monsoons.
Meanwhile,many parts of the country are experiencing heatwave conditions with the temperature crossing 45 degrees Celsius. Maharashtras Vidarbha,Orissa,Madhya Pradesh,Rajasthan and other parts of the country are going through heatwave conditions. The IMD has predicted similar conditions to prevail over many parts of the country over the next 48 hours.
Showers lash city
Many parts of Pune city witnessed rain and thundershowers on Monday. The IMD attributed this to local climatic conditions. This was the second spell of pre-monsoon showers for Pune. The IMD predicts more rain and thundershowers in the city in the next 48 hours.
Due to the ongoing heatwave conditions in Vidarbha,the mercury has shot up several notches and touched the 39-degree mark in Pune. Dr S Gaonkar,senior scientist at IMD,said clear sky conditions,lack of moisture in the air had increased the temperature.
