The India Meteorological Department (IMD) has been issuing yellow and orange alerts for some parts of the state, signaling a severe cold snap.
Meteorological departments issue district-level and subregional-level warnings and district-level and station-level nowcasting warnings, describing the current weather conditions in detail.
Why use color?
According to the IMD, the color codes are used in weather warnings to emphasize the severity of the current situation. The aim of this is to alert relevant officials and disaster management authorities of the impact of weather conditions and help them prepare for necessary actions related to disaster risk reduction.
What are the colors used and what do they represent?
Four colors are used for warnings: green, yellow, orange and red. Each has its own meaning and comes with a set of protocols. These warnings are updated daily.
Green (>15°C) means everything is OK and no advisories have been issued. This means that there are no unusual changes in the weather.
Yellow (>10 to <=15°C) indicates authorities should take note. In these conditions, severe severe weather can be expected. It also indicated that the weather could get worse, disrupting daily activities.
Orange or amber (>4 to <=10°C) is a "be ready" warning. This is a warning of extreme severe weather.
A red alert (<= 4°C) urges the authorities to take action. This means that the weather is very bad.
Color warnings are used for all weather conditions, including rainfall, cold snap and heat wave conditions.
