Delhi Braces for Rain Relief After Sizzling Temperatures and Evening Dust Storm
Delhi residents recently endured a period of intense heat, with temperatures soaring significantly above the seasonal average. However, relief is on the horizon as the India Meteorological Department (IMD) forecasts light rain and gusty winds, expected to bring down the mercury and offer a much-needed reprieve from the scorching conditions.
Monday witnessed particularly hot weather, with the capital recording temperatures up to 4 degrees Celsius higher than usual. While these figures were discomforting, they narrowly missed the official criteria for a heatwave. The evening brought a dramatic shift, as a powerful dust storm swept across the city, followed by a forecast of cooler, wetter weather.
Recent Weather Snapshot: High Temperatures and a Dust Storm
The city’s primary weather station, Safdarjung, reported a maximum temperature of 42.3 degrees Celsius on Monday. The Ridge area in North Delhi felt even hotter, peaking at 43.8 degrees Celsius. Despite these high readings, the IMD confirmed that a heatwave was not officially declared, as the conditions did not meet the specific thresholds.
The day concluded with a significant weather event: a dust storm that descended upon the city between 8 PM and 9 PM. Gusty winds, reaching speeds of up to 61 km/h at Pragati Maidan and 54 km/h at Pusa, accompanied the storm. While no rainfall was recorded immediately after the dust storm, it signaled an upcoming change in the weather pattern.
Anticipated Relief: Rain and Temperature Drop
The IMD has issued a yellow alert for the coming days, indicating a high likelihood of light rain and thundershowers. This meteorological shift is expected to significantly impact Delhi’s temperature profile, potentially bringing daily highs below the 40-degree Celsius mark. The forecast suggests the following:
- Tuesday: Partly cloudy skies with a chance of light drizzle in isolated areas.
- Wednesday: One or two spells of light rain are anticipated, accompanied by gusty winds reaching up to 50 km/h. This is the period when temperatures are most likely to fall below 40 degrees Celsius.
- Continuing Trend: Officials predict a cooling trend to persist for several days, with light rain possible through Wednesday and Thursday. Daytime temperatures are expected to hover between 39 and 41 degrees Celsius until early May.
Mahesh Palawat from Skymet Weather elaborated on the upcoming weather system, explaining that the expected rainfall is linked to a weather disturbance originating over central Pakistan and extending to nearby Rajasthan. Moisture from the Arabian Sea is also contributing to the conditions favoring precipitation in the region, which is expected to move towards Delhi via Haryana.
Understanding Heatwave Criteria in Delhi
The IMD defines a heatwave based on specific temperature and deviation criteria. A heatwave is declared when:
- Temperatures are at least 4.5 degrees Celsius above normal and exceed 40 degrees Celsius, OR
- The absolute temperature reaches 45 degrees Celsius or higher, regardless of the normal deviation.
On Monday, despite the elevated temperatures, Delhi did not meet these stringent conditions, meaning it avoided an official heatwave declaration for that day. However, the city had experienced three consecutive days of heatwave conditions from Thursday to Saturday the previous week, with Saturday being the hottest day of the year so far.
Heatwaves in April are not an unusual phenomenon for Delhi. Historical data shows similar occurrences, with three heatwave days recorded in early April last year, and a more significant 11 heatwave days in April 2022.
