The monsoon season often brings several risks and uncertainty. While moderate rainfall can provide some relief, heavy storms can cause massive damage to life and property. To ensure people get the required time to prepare for such calamities, a weather alert system has been implemented. This colour-coded weather alert system is used by the Indian Meteorological Department (IMD) to simplify complicated data into categories simple to understand. When these alerts are issued, citizens get to determine the risks associated with the provided weather conditions. It aids in better preparation, guaranteeing the safety of the commoners. Today let’s discuss the meaning and dangers associated with every weather alert.
Why are colours used?
As per the IMD, “Colour codes are used in weather warnings for bringing out the severity of the weather phenomena expected.” The primary idea behind this colour code is to forewarn relevant officials about the potential impact of the expected weather. This helps the authorities prepare for necessary action to reduce the risk of disasters.
All 4 Monsoon Alerts (Green to Red):
Green Alert (less than 70mm/hr)
The green alert refers to normal weather that involves little to no rainfall. If a green alert is ever issued, it means that there is no forecast for severe weather conditions. People can go outside without having to worry and carry on with their daily activities.
Yellow Alert (64.5 to 115.5mm/24 hrs)
Yellow alert usually demands citizens to be aware that there may be a chance of moderate rainfall. While this forecast highlights that the rainfall won’t be particularly heavy, it can cause flooding in low-lying regions. Hence, people living in the impacted areas should exercise caution and carry umbrellas when going outside.
Orange Alert (115.6 to 204.4 mm/24 hrs)
The orange alert typically indicates heavy rainfall and storms. This particular forecast refers to a high risk of flooding in streets, rivers and other vulnerable zones. Citizens should stay inside until the rain stops. They should stock up on essential supplies while also preparing themselves for potential power cuts, landslides and lack of transportation.
Red Alert (greater than or equal to 204.5 mm/24 hrs)
Red alert is the most severe weather forecast indicating extremely heavy rainfall that can cause significant damage to life and property. Prioritising safety is essential during a red alert. Avoid leaving your home at all costs and follow the instructions from the local authorities.
