IMD Alert: After Holi, a sudden big change is being seen in the weather. While the heat has made its first steps in different parts of the country, heat wave-like conditions are prevailing at many places in the southern state of Kerala. The meteorological department has also issued an alert for the next five days. In Thrissur, Kerala, the temperature has already reached almost 40 degrees Celsius.
The India Meteorological Department (IMD) on Tuesday (26 March) issued a warning for the next five days i.e. till 30 March, saying that the mercury in Thrissur will reach 40 degrees and the mercury in Kollam-Palakkad will reach 39 degrees Celsius. At present, the highest temperature recorded in Thrissur on Monday and Tuesday was 39.9 degrees Celsius and 39.8 degrees Celsius respectively, which is about four and a half degrees Celsius more than the average temperature.
What is the criteria for declaring a heat wave?
According to the report of The Hindu, to declare a heat wave, the temperature in an area at that time should be 4.5 degrees Celsius more than normal. The maximum temperature of the coastal area should be greater than or equal to 37 degrees Celsius. If all these parameters are considered, the weather conditions for declaring heat wave in Thrissur have technically been met. Although the India Meteorological Department has not announced it officially.
Will heat break records in these areas?
IMD sources say that to know the average normal temperature of an area, at least 30 years of data is required. IMD sources say that with no major summer rainfall forecast for the next seven days, the maximum temperatures are likely to remain high in the coming days. According to IMD’s record book, Vellanikkara in Thrissur, Punalur in Kollam and Palakkad will be the hottest areas in the month of March.
