The India Metrological Department (IMD) under Ministry of Earth Sciences issues forecast and colour coded warnings for severe weather events including heat waves. 

IMD in collaboration with local health departments have started the heat action plan since 2013 to forewarn people about the heat waves and advise preventive actions. 

The Heat Action Plan, implemented in 23 States, in collaboration with National Disaster Management Authority (NDMA), is a comprehensive early warning system and preparedness plan for extreme heat events constituting immediate as well as longer-term actions to increase preparedness, information-sharing, and response coordination to reduce the health impacts of extreme heat on vulnerable populations. 

A report by Intergovernmental Panel for Climate Change (IPCC) stated that the population of insects is expected to rise across the world and enhance crop destruction due to global warming.

Regarding this, IMD issues agro-meteorological advisories through Gramin Krishi Mausam Sewa (GKMS) scheme every Tuesday and Friday for 700 agriculturally important districts and around 3100 blocks by 130 Agromet Field Units (AMFUs) and 199 District Agromet Units (DAMUs). 

These advisories include the information regarding pests and diseases which affect agriculture and Pest-Weather calendars prepared for every crop. 

Seasonal Outlook is an initiative by IMD, which depicts the expected scenario of heat waves by estimating temperatures for April, May & June in the last week of March. 

This is followed by Extended Range Outlook, issued every Thursday for next two weeks. Heat wave warnings are issued for next 5 days with outlook for next 2days.
