Met department colour alerts explained: How to stay safe during extreme weather
Each year, India faces a variety of extreme weather events, including heat waves, thunderstorms, heavy rains, cold waves, and storms. To keep the public informed and safe, the India Meteorological Department (IMD) employs a colour-coded alert system. This system consists of four colours—green, yellow, orange, and red—each with a specific meaning.If you are making travel arrangements, entering into a school program, or working day to day, etc., it will assist you in determining the best course of action. It is important to be aware of all of these alerts. Let's explore what each of the colours means and how you should prepare for them.advertisementWHY ARE THESE CODES USED?
The IMD's colour-code weather alert system serves the primary purpose of putting weather information into a simple, easy-to-understand category system. In this way, when these alerts are issued, people get the opportunity to assess how potentially hazardous the weather that is about to occur may be by understanding and appreciating what these colours mean. This helps citizens prepare properly, minimises the impact of inclement weather, and ensures their safety.SIGNIFICANCE OF THE COLOUR CODESThe IMD uses four colours are orange, red, yellow, and green. The varying shades reflect different degrees of potential risk, which allows people to place a commensurate level of preparedness.GREEN ALERT (NO ADVISORY)The green alert means there are normal weather conditions with little or no rain. This is generally accompanied by weak, intermittent rain or dry weather during the monsoon. Essentially, when this Alert is issued, it also means there are no serious weather-related issues, and it is a situation where people can go outdoors and conduct their everyday business as they please.advertisementYELLOW ALERT (BE AWARE)A yellow alert is issued when there is a chance of significant rainfall. It's important to understand that a yellow alert does not guarantee heavy rain; rather, it indicates a possibility of isolated flooding in low-lying areas and potential disruptions to outdoor activities. Residents in affected areas should remain vigilant, especially in places prone to frost. It's advisable to drive carefully and bring umbrellas.ORANGE ALERT (PREPARE FOR IMPACT)An orange alert is issued when intense rainfall is expected; usually, 115.6 mm and up to 204.4 mm of rain are predicted in 24 hours. An orange alert indicates an increased chance of flooding in streets, streams and vulnerable areas. Residents should remain indoors if possible, stock supplies, and be ready for possible transportation issues, loss of power and potential landslides.RED ALERT (TAKE ACTION)The red alert is the most serious of weather warnings; extreme heavy rainfall of over 204.5 mm is predicted in 24 hours. A red alert indicates a serious threat to life and property with the potential for a degree of flooding, disruption to essential services and the need to evacuate. Under a red alert, personal safety is paramount; do not travel and obey local authorities.Understanding the IMD colour-coded alerts is critical for personal safety during the monsoon. By observing the alerts, residents can take appropriate action based on the predicted weather that will keep them safe at a time of unpredictable weather. Be it a light shower or a red alert, the key to weathering the monsoon is awareness.

Thrissur reels under heavy rain
Torrential rain over the last two days has wreaked havoc across low-lying areas of Thrissur district, with severe waterlogging reported especially in the coastal regions. Hundreds of houses have been inundated, crippling normal life. In Chavakkad, one of the worst-hit regions, floodwaters submerged vast stretches as the Canolly Canal and Mathikayal overflowed. Though sea erosion has not turned extreme, areas such as Munakkakadavu, Velichenna Padi, and Thottappu continue to experience coastal incursion. The overflow of the Canolly Canal has caused serious flooding in Vanchikkadavu and Thekkancheri, with dozens of houses marooned. In Vanchikkadavu, 19 residents from three heavily-affected houses were evacuated to the Anjangaadi government Shelter, where they are being provided with essential facilities, according to municipal chairperson Sheeja Prashanth. While there was a brief pause in the rain last night, intense downpours and strong winds resumed after midnight. The wind uprooted trees and damaged power lines in several areas, resulting in prolonged power outages. Fishing activities have been suspended until further notice, leaving traditional fishermen and allied workers stranded without daily earnings. Floodwaters left roads broken, posing threat for motorists. The Chetuva road of National Highway 66 has suffered serious damage between South Bypass and Williams Junction, forcing vehicles to reroute through coastal roads. Parts of the NH 66 service road remain submerged or eroded, with blocked stormwater drains causing further flooding. In many places, hidden potholes beneath waterlogged roads have led to accidents involving two-wheelers and pedestrians. Lightning storm Meanwhile, in Puthanpeedika, a sudden lightning storm and mini whirlwind around 8.45 p.m. on Sunday night caused widespread destruction near St. Antony's High School. Roofs with truss work were ripped off and scattered onto nearby roads. The roof of the school's ladies' restroom and football nets were also blown away. Uprooted trees blocked roads. Power supply to the area disrupted for many hours. In Wadakkanchery, a massive tree fell on the Sree Vyasa NSS College road in Parlikkad in the wee hours on Monday, blocking the road for hours. Forest department personnel later removed the tree and restored vehicular movement.
