• A red alert implies a “take action” warning, urging residents to avoid heat exposure, remain hydrated and limit outdoor activity. It warns of a very high likelihood of developing heat illness and heat stroke in all ages and advises extreme care for vulnerable people.

• Dr Naresh Kumar, a senior scientist at IMD, stated that the severe heat across northwest India -- including Delhi, Punjab, Haryana, and Rajasthan -- is expected to persist till June 12.

• From June 13, an approaching western disturbance may bring partial relief in the form of light rain and thunderstorms, and an orange alert will replace the red.

• "Northwest India is currently experiencing severe heat. Over the next 3-4 days, heatwave conditions are expected in Punjab, Haryana, Rajasthan, Jammu & Kashmir, Himachal Pradesh, northern Madhya Pradesh, and Uttar Pradesh. Punjab, Haryana, and Rajasthan will remain under red alert for the next three days.

• "Delhi-NCR is under red alert today and tomorrow, followed by an orange alert on June 13. Light rain and thunderstorms are possible on the night of June 13 due to a western disturbance, which may bring some relief," Kumar told PTI.
•  
  
• The city also reported poor air quality, with an AQI of 225 at 2 pm. The IMD has forecast partly cloudy skies for June 12 and 13 with dust-raising winds gusting up to 60 kmph during thunderstorms.

• Authorities have urged citizens to take precautionary measures, particularly vulnerable groups such as children, the elderly and those with pre-existing health conditions.

• According to IMD data, temperatures are expected to dip slightly after June 14, with possible light to moderate showers bringing some respite from the scorching heat. Until then, the capital remains on high alert as extreme temperatures continue to pose health and safety risks.
