New Delhi, July 4 (TIWN) Even as Monday witnessed a sultry weather in the national capital, the rain from the previous day washed off much of the pollutants in the environment resulting in an overall 'satisfactory' air quality.

India Meteorological Department (IMD) forecast for Monday predicted generally cloudy sky with light rain. It has forecast moderate rain for Tuesday and heavy rain for Wednesday.  Not just Delhi, the IMD has predicted isolated rainfall activity over Punjab, Haryana, Chandigarh, Uttar Pradesh and Rajasthan during next 24 hours and scattered to widespread rain with isolated thunderstorm/lightning over the region between July 5 and 8.  On Sunday, few places in Delhi such as Pitampura, Delhi University and Ridge (north Delhi) registered a rainfall above 20 mm while in rest of the areas, it was either ‘traces’ or fairly negligible rainfall.  “AQI today indicates ‘satisfactory’ air quality with dust (particle size more than 2.5 micrometer) contribution at approximately 57 per cent to PM10. For the next three days, i.e., till July 7, peak wind speed is likely to be about 15-20 kmph causing moderate dispersion and AQI is likely to be within asatisfactory’ due to expected light rain spells,” the System of Air Quality and Weather Forecasting and Research (SAFAR), under the Indian Institute of Tropical Meteorology (IITM), Pune, said.
