It has been a cool Sunday for Delhiites as a steady morning drizzle drenched the capital today, bringing down the temperature. Intermittent rain continued to lash the national capital since morning and brought with it waterlogging and traffic jams. Since it was a Sunday, traffic snarls did not inconvenience commuters. Delhiites had a muggy day yesterday with a rise in temperature and high humidity even as some parts of the capital received monsoon showers. The skies will remain cloudy and there is a possibility of heavy rain in some parts of the city, while other areas may receive moderate showers.
