‘Hot Day Condition’ declared for the next two days

A forecasting officer from the Indian Meteorological Department said, “The met department has declared ‘Hot Day Condition’ in the city. The reason for the extreme heat in the city is due to a depression in the air pressure in the city. This depression is now attracting the western winds which originate from the desert areas of the country. It is this hot air that is building up the temperature in the city.”

What is Hot Day Condition?

When maximum temperature departure is 5º C or more from normal, hot day may be described irrespective of the threshold value of 40º C. If the threshold value of 40º C is reached a ‘Heat Wave’ may be declared.
