What Is an IMD Weather Alert?
An IMD weather alert is an official warning issued by the India Meteorological Department in case there is a possibility of significant weather activity.

Why Does Delhi-NCR Experience Sudden Weather Changes?
Delhi-NCR’s geographical location and seasonal weather patterns often result in rapid weather changes. In the pre-monsoon and monsoon season, thunderstorms can develop quickly because of changes in temperature, humidity and atmospheric conditions. These systems can bring about sudden rain, gusty winds and lightning in a short span of time.
What Does a Red Alert Mean?
IMD has four levels of weather warning – red, orange, yellow and green. This means that severe weather conditions are expected, which may cause major disruption, damage or danger to life and property. In the event of a red alert, authorities are advised to take immediate action and people are advised to avoid unnecessary travel and to follow official safety instructions. Usually, red alerts are issued in Delhi-NCR during heavy rainfall, severe thunderstorms, lightning or strong winds.
What Does an Orange Alert Mean?
An orange alert is issued when severe weather is expected and people are advised to be ready. It means the weather could get dangerous with a chance of heavy rain or thunderstorms or lightning or strong winds. During an orange alert, residents should keep an eye on official forecasts and be ready for possible disruptions such as waterlogging, traffic problems and power cuts.
Difference Between Red Alert and Orange Alert
The key difference between red and orange alerts is the level of severity and the response needed. There is a red alert when action needs to be taken immediately because there is a chance of extreme weather and an orange alert when people need to be prepared and stay cautious as severe weather may happen. Both alerts are for hazardous weather, but the expected impact is higher in red alert.
What Is a Yellow Alert?
A yellow alert is issued when authorities want people to remain aware and updated with changing weather conditions. It means weather activity is not quite extreme but could still be problematic. People are advised to watch the forecasts and to be careful, especially during thunderstorms or heavy rains.
Why Does IMD Issue Rain Alerts?
IMD issues rain warnings to mitigate the risks of extreme weather events. Heavy rain can cause flooding, waterlogging, disruption to traffic and damage to infrastructure. Also, thunderstorms and strong winds can cause problems such as falling trees, power failures and unsafe travel conditions. Early warnings enable authorities and citizens to act preventively.
How Does IMD Predict Severe Weather?
The India Meteorological Department (IMD) uses advanced weather monitoring systems, satellites, radar technology and weather models to forecast weather conditions. Meteorologists look at elements like cloud formation, wind patterns, atmospheric pressure and moisture levels to forecast rainfall and storms. Such forecasts help locate the potential development of extreme weather.
What Should People Do During a Red Alert?
Authorities have instructed people to stay indoors during thunderstorms and avoid unnecessary movement outdoors during a red alert. Do not drive through flooded roads and keep away from trees and electric poles in strong winds and be prepared with emergency supplies if needed.
What Should People Do During an Orange Alert?
Orange alert means people should be careful and plan their travel accordingly. Residents need to be alert for weather updates, avoid unsafe areas and take precautions against heavy rain and thunderstorms. Passengers should brace for possible delays due to traffic disruptions or waterlogging.
Impact of Heavy Rain in Delhi-NCR
Heavy rains in Delhi-NCR can throw up a host of problems, disrupting daily life with traffic congestion, waterlogging, flight delays and disruption to public transport. Due to high population density and pressure on urban infrastructure, areas across Delhi, Noida, Ghaziabad and Gurugram can face problems during heavy rainfall.
