The IMD uses four colour codes:

[{"selector":"#anim-43cf02a2-4eb2-48d6-bba1-577de0b831e9","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-6e0b2e09-53c9-4618-a1da-4ef3f436cfa3","keyframes":{"transform":["translate3d(-116.72475%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-aa4b42a3-8ea4-4928-8a65-43754ea16a1e","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-80a7a592-4c2a-4139-8aa9-f6e4b474c0fb","keyframes":{"transform":["translate3d(-115.09434%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

These alerts are universal and are also issued during floods, depending on the amount of water rising above land/in a river as a result of torrential rainfall.

For more specific weather events such as rainfall, thunderstorm, lightning, etc these colours point out more warning.

Know everything about colour-coded alerts issued by the IMD

Why are colour codes used?

These colour codes alert people ahead of severe or hazardous weather which has the potential to cause damage, widespread disruption, or danger to life.

How is the colour forecast decided?

The decision of the colour depends on the meteorological, hydrological, and geophysical factors that indicate the risk.

The IMD uses four colour codes:

Green – No Action is needed Yellow – Watch and stay updated Orange – Be prepared Red – Take action

These alerts are universal and are also issued during floods, depending on the amount of water rising above land/in a river as a result of torrential rainfall.

For more specific weather events such as rainfall, thunderstorm, lightning, etc these colours point out more warning.
