The IMD has issued a severe weather alert for north and central India, forecasting heavy to very heavy rainfall driven by a low-pressure system. East Rajasthan and West Madhya Pradesh are expected to be the hardest hit.

Key Takeaways

  • Isolated extremely heavy rainfall predicted for East Rajasthan.
  • Heavy rain alerts for Delhi-NCR, Haryana, Punjab, and Himachal Pradesh.
  • Low-pressure area over NW Madhya Pradesh driving the current weather pattern.
  • Widespread rain expected to persist across the western Himalayas and Konkan-Goa for a week.

The southwest monsoon is set to remain aggressively active across several parts of India on Wednesday, August 12. According to the India Meteorological Department (IMD), a low-pressure system over northwest Madhya Pradesh is fueling intense precipitation across the northern and central belts of the country.

Rajasthan and Central India: The Epicenter of Rain

East Rajasthan is currently the primary hotspot for rainfall. The IMD has warned of isolated extremely heavy spells in the region. The intensity is already evident, with Bakani in Jhalawar recording a staggering 27 cm of rain and Pirawa recording 26 cm within a 24-hour window. Similarly, West Madhya Pradesh is braced for heavy to very heavy rainfall, creating risks of localized flooding.

Why This Matters (BozokMedia Analysis)

BozokMedia analysis indicates that the current positioning of the monsoon trough—extending from Rajasthan through Uttar Pradesh to the Bay of Bengal—is creating a 'corridor of precipitation.' While this is beneficial for groundwater recharge, the concentration of rain in short bursts poses a significant threat to urban drainage systems in cities like Delhi and Jaipur.

"The formation of successive low-pressure areas in the Bay of Bengal suggests a prolonged and volatile monsoon phase this year."

Delhi-NCR and Southern India Outlook

The Delhi-NCR region, including Haryana and Chandigarh, is expected to experience another wet day. Recent data shows Babain and Ganaur in Haryana have already seen significant rainfall. Meanwhile, Southern India will not be spared, with widespread showers predicted for coastal Karnataka and Kerala, and scattered thunderstorms across Andhra Pradesh and Tamil Nadu.

Region Intensity Level Key Affected Areas
Extremely Heavy Critical East Rajasthan, W. Madhya Pradesh
Heavy to Very Heavy High Delhi, Punjab, Gujarat, Odisha
Widespread Showers Moderate Kerala, Karnataka, Tamil Nadu
Did You Know?: The 'Monsoon Trough' is an elongated zone of low pressure that acts as a magnet for moisture-laden winds from the ocean, organizing the rainfall patterns across the subcontinent.
