The national capital will continue to have monsoon activity till the weekend and a break, thereafter. The weather activity will be scattered and patchy, and may not be simultaneous over the entire area of Delhi/NCR. In the last 24 hours, some parts of Delhi and suburbs received light rain. The base station at Safdarjung and the airport Observatory at Palam recorded fleeting showers, measuring 0.8mm and 0.3mm, respectively.
The monsoon trough is the main trigger for the weather activity in Delhi. This trough is moving closer and therefore, the associated rainfall may increase over the next 48 hours, on 04th and 05th September. The low-pressure area lying earlier over Madhya Pradesh has moved to Southeast Rajasthan. The system will have an incremental shift over the central and eastern parts of the state. The monsoon trough will run in close proximity to Delhi. Also, there is a feeble upper air westerly system passing across the northern mountains. Under the combined influence of these two systems, scattered showers are likely over and around Delhi, lasting till the weekend.
Monsoon activity was on the poorer side for Delhi in June, for the first three weeks. Thereafter, the frequency of rainy days and intensity and spread of rainfall have been fairly decent. July and August, the rainiest months for Delhi, delivered better than expected. The representative observatory at Safdarjung has registered 861mm of rainfall during the monsoon season, so far, against the normal of 542mm, an excess of over 50%. More showers are likely during this week, to add to this total. The monsoon withdrawal is generally seen between the 20th and 25th of September, with exceptions of extension till the month's end. Moderate showers are expected between 04th and 06th September. The intensity and coverage of showers may reduce on Saturday and Sunday. The day maximum is likely to hover around 34°-35°C and the minimum temperature will stay around 24°-25°C, during this period. The next week may start on a drier note, raising the mercury levels.
