Delhi Weather Update: IMD Issues Yellow Alert; Heatwave Likely Till April 24, Temperature To Hit 43°C

The India Meteorological Department (IMD) has forecast a sharp rise in temperatures across Delhi this week, signalling the arrival of the season's first major heatwave spell. According to the latest outlook, daytime temperatures are expected to climb steadily from around 41-42°C at the start of the week to nearly 43°C between April 21 and April 24, pushing conditions into heatwave territory.

Heatwave Yellow Alert in Delhi-NCR: Temperatures Set to Touch 43°C

In a first for the current season, the IMD has issued a yellow alert warning of heatwave conditions in isolated parts of the national capital from Wednesday to Friday. The alert indicates potentially uncomfortable weather, with maximum temperatures likely to remain elevated and pose health risks, especially during peak daytime hours.

As per official criteria, a heatwave in India is declared when maximum temperatures in the plains cross 40°C and remain at least 4.5°C above normal for two consecutive days, or when temperatures hit 45°C irrespective of deviation. More extreme conditions are classified as severe heatwaves when the mercury touches or exceeds 47°C.

Weather Forecast for April 22 to April 24

The IMD expects temperatures to remain persistently high over the next few days. On April 22, the maximum temperature in Delhi could reach around 42°C, with the minimum hovering near 22°C. Heatwave conditions are likely to prevail throughout the day, affecting morning, afternoon and evening hours.

The trend is expected to continue on April 23 and April 24, with daytime temperatures staying close to 42°C and nighttime temperatures rising slightly to around 23°C. This sustained heat is likely to intensify discomfort levels across the city.

Rising Humidity to Make Conditions More Uncomfortable

Apart from high temperatures, humidity is also expected to rise significantly, worsening overall weather conditions. By April 24, humidity levels could reach up to 70%, leading to hot and humid, or sultry, conditions. The combination of heat and moisture in the air can increase the "feels-like" temperature, making it harder for the body to cool down.

Delhi Air Quality Turns 'Poor' Again

Alongside rising temperatures, air quality in Delhi has deteriorated once again. The Air Quality Index (AQI) has climbed to 258, placing it in the "poor" category. This marks a decline from the "moderate" level of 152 recorded after rainfall last week. Forecasts suggest that air quality may continue to remain in the poor range until at least Wednesday, adding to public health concerns.

Advisory Issued for Residents

Authorities have urged residents to take necessary precautions as the heatwave intensifies. People are advised to avoid outdoor activities during peak afternoon hours, stay hydrated, and wear light, breathable clothing. Vulnerable groups such as children, the elderly, and those with pre-existing health conditions are particularly at risk during such extreme weather conditions.
