IMD Predicts More Intense Rainfall as Season Peaks

As India grapples with severe weather events across multiple states, the India Meteorological Department (IMD) has issued forecasts indicating above-normal monsoon rainfall for the latter half of the season. With recent tragedies in Kerala, Uttarakhand, and Himachal Pradesh highlighting the devastating impact of extreme rainfall, the IMD’s projections for August and September have drawn significant attention. Here are the key takeaways from the IMD’s recent announcements and related developments:

1. IMD predicts above-normal monsoon rain for August and September, with rainfall likely to exceed 106% of the Long Period Average (LPA).
2. August is expected to receive normal monsoon rainfall, while September may see higher-than-average precipitation.
3. La Nina or La Nina-like conditions are anticipated to develop by late August, potentially contributing to increased September rainfall.
4. July recorded 9% more rainfall than normal, aligning with the IMD’s earlier forecast of “above normal” precipitation for the month.
5. Heavy rainfall in September could potentially damage standing crops, as observed in Madhya Pradesh two years ago with soybean crops.
6. Unusual heavy rain in September and October may affect winter sowing patterns and exacerbate air pollution in northern India.
7. In July, 1,223 weather stations reported heavy or very heavy rainfall, defined as 11 cm or more in a 24-hour period.
8. The IMD issued early warnings for Kerala’s heavy rainfall, including an orange alert on July 29 and a red alert on July 30.
9. Delhi received orange alerts two days in advance of its recent intense rainfall event.
10. The IMD employs a color-coded warning system to inform the public and authorities about expected rainfall intensity, with orange and red alerts signaling the need for preparatory action.
