  1. Dust bowl Delhi lashed by hot winds: All about today's weather conditions The conditions may prevail till light showers bring respite to Delhi and adjoining regions around June 16 and 17.

  2. Air quality in Delhi remained beyond "severe" level for the third day on Thursday, as authorities warned the prevailing dusty conditions were likely to prevail for three-four days and advised people to avoid staying outdoors for long hours. The national capital woke up under the shade of dust with the minimum temperature recorded at 34 degrees Celsius, five notches above the season's average. The maximum temperature is likely to hover around 41 to 42 degrees Celsius. By 9.30am, the temperature at Palam was already 35 degrees Celsius. How bad is it The PM10 level (presence of particles with diameter less than 10mm) was beyond severe at 796 in Delhi-NCR and 830 in Delhi particularly, leading to hazy conditions. According to the CPCB, the air quality index — a measurement of the concentration of toxic particulate matter in the air — at several places in Delhi remained beyond the 500- mark, with east Delhi's Anand Vihar area recording a PM10 level of 929 and PM2.5 level of 301 this morning. An AQI between 0-50 is considered “Good”, 51-100 “Satisfactory”, 101-200 “Moderate”, 201-300 “Poor”, 301-400 “Very Poor”, and 401-500 "Severe". The CPCB said pollution this summer is very different from last year. In November, both PM2.5 and PM10 spiked in the Delhi-NCR region, posing serious health hazard to residents. The increase in pollution levels now is mainly due to drastic increase in coarse particles in air. This time the PM2.5, ultra-fine particles that may reach lungs and affect its functioning, is not as high as that of November last year.
