The Indian Meteorological Department (IMD) utilizes a system of four colour-coded weather warnings to communicate the severity of weather conditions and caution people about possible widespread disruption or life-threatening situations:
- Green (No advisory): No advisory is given.
- Yellow (Be Aware): This signifies prolonged and severe weather conditions that could potentially worsen, causing disruption in day-to-day activities.
- Orange (Be Prepared): The orange alert warns of extremely severe weather conditions that could lead to road and rail closures, interruption of power supply and other disruptions in commute.
- Red (Take Action): The red alert is issued when weather conditions are expected to cause significant risk to life, travel and power disruptions.
For areas prone to cyclones, the IMD issues warnings to state government officials in four stages:
- Pre-Cyclone Watch: Issued 72 hours in advance, this early warning indicates the development of a cyclonic disturbance in the north Indian Ocean.
- Cyclone Alert: Issued at least 48 hours prior to the expected onset of adverse weather over coastal areas.
- Cyclone Warning: Issued at least 24 hours in advance and predicts the landfall point of the cyclone.
- Post Landfall Outlook: Issued at least 12 hours in advance of the anticipated landfall time, it predicts the expected direction of the cyclone’s movement after landfall.
