] IMD Weather Update: Rain Alert for Delhi-NCR From May 11; Severe Storms to Hit UP, Bihar, and West Bengal

Now the scorching summer heat in North India is set to take a backseat as a fresh weather system moves across the subcontinent. The India Meteorological Department (IMD) has issued a yellow alert for Delhi-NCR starting May 11, predicting a welcome round of thunderstorms and rain. Therefore, while April witnessed record-high temperatures, May is emerging as a much cooler month due to the frequent presence of Western Disturbances. Meanwhile, severe storms with wind speeds of up to 70 km/hr are expected to strike East India, bringing both relief and caution to the region.

Delhi-NCR: Three-Day Rain Alert and Temperature Forecast

Now a significant shift in climate patterns is approaching the national capital. The IMD has officially issued a yellow alert for May 11 and 12, warning of thunderstorm activity paired with gusty winds and rain. Therefore, the current pleasant climate will intensify into a more volatile weather system early next week.

First, maximum temperatures during this period are forecast to remain around 39°C. Next, the minimum temperatures will likely hover around the 28°C mark. Thus, while the heat remains present, the arrival of moisture will prevent the extreme “Loo” winds typical of this season.

So May 9 and 10 will continue with relatively clear skies and temperatures touching 37°C. Meanwhile, the city administration is preparing for potential waterlogging in low-lying areas. Therefore, residents are advised to monitor official updates before planning outdoor activities on Monday.

The ‘Cooler May’ Phenomenon: Impact of Western Disturbances

Now many residents have noticed that May 2026 is turning out to be cooler than the previous month. This unusual trend is primarily due to a high frequency of Western Disturbances entering the Indian landmass. Therefore, the record-breaking heat of April has been replaced by a cycle of intermittent cloud cover and showers.

First, these disturbances originate in the Mediterranean and bring moisture to North and Northwest India. Next, they interact with local heating to create the sudden thunderstorms currently being witnessed. Thus, the traditional “peak summer” feeling has been delayed by these recurring climatic shifts.

So while the relief is welcome, the humidity levels are expected to rise following the rainfall. Meanwhile, the IMD bulletin suggests that this pattern may continue for at least another week. Therefore, the energy demand for cooling may see a slight fluctuation compared to previous years.

North India: Storms to Strike from Punjab to Kashmir

Now the weather changes in Delhi are part of a much larger system affecting the Himalayan regions and the Northwest Indian plains. Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Punjab, and Haryana are all expected to witness a sharp change from May 11. Therefore, these areas are now under various levels of weather warnings.

First, the IMD has issued both Yellow and Orange warnings for these states valid until May 14. Next, winds in these northern regions may blow at speeds of 50 kilometers per hour. Thus, travelers to hill stations are being urged to exercise caution due to the risk of landslides and sudden squalls.

So the combination of hail and rain could impact late-harvested crops in the plains. Meanwhile, the snowmelt in the higher reaches may also see a brief slowdown due to the drop in temperature. Therefore, the entire northern belt is bracing for a four-day period of atmospheric instability.

Rajasthan vs. Uttar Pradesh: Heatwaves Meet Dust Storms

Now the weather battle between Rajasthan and Uttar Pradesh continues to produce extreme data points. Recently, Phalodi (44.8°C) and Barmer (44.6°C) registered the highest temperatures of the season. Therefore, Western Rajasthan remains the primary epicenter of the remaining heatwave in India.

First, new heatwaves are forecasted for Western Rajasthan as early as May 9. Next, this will be followed by a sharp transition to dust storms and light to moderate rainfall starting May 11. Thus, the incoming weather system is expected to bring down temperatures by a substantial 3–5 degrees across the desert state.

So Uttar Pradesh will also benefit from this cooling effect through mid-week. Meanwhile, the dust storms may temporarily reduce visibility on major highways connecting the two states. Therefore, the transition from extreme heat to stormy weather will be rapid and widespread.

East India: Severe Weather and Hailstorm Alerts

Now the most volatile weather conditions are predicted for the eastern states. West Bengal, Bihar, and Jharkhand are expected to face severe weather systems with maximum wind speeds reaching 70 km/hr. Therefore, the potential for structural damage and uprooted trees is significantly higher in these regions.

First, there is a specific alert regarding hailstorms that may occur in isolated pockets of Jharkhand. Next, Bihar and Odisha are forecasted to experience light to moderate showers accompanied by lightning. Thus, the eastern corridor is currently under high alert for “Kal Baisakhi” style storms.

So the lightning activity in Bihar is particularly concerning for those working in open fields. Meanwhile, the coastal regions of Odisha are seeing a longer window of volatility from May 8 to May 12. Therefore, disaster management teams have been put on standby to handle potential power outages.

South India: Heavy Showers and Coastal Squalls

Now the southern peninsula is also preparing for a surge in pre-monsoon activity. Isolated heavy showers are predicted for Tamil Nadu, Puducherry, Kerala, and South Interior Karnataka. Therefore, the southern agricultural belt is likely to receive a much-needed moisture boost this week.

First, coastal Karnataka and the Lakshadweep islands will experience squalls with wind speeds of 30–50 km/hr. Next, these conditions are expected to prevail until May 12, affecting maritime activities. Thus, fishermen have been advised against venturing too deep into the sea during this period.

So the heavy rainfall in Kerala is a precursor to the eventual arrival of the Southwest Monsoon. Meanwhile, the South Interior Karnataka region will see a reprieve from the recent dry spell. Therefore, the national weather picture for the second week of May is one of widespread, albeit varied, precipitation.

Agricultural Impact: Preparing for Late-Season Rainfall

Now the timing of these storms is a double-edged sword for the Indian farming community. While the cooling effect is beneficial for summer crops, the high wind speeds and hailstorms can be destructive. Therefore, farmers in North and East India must take immediate steps to protect their produce.

First, standing crops like mangoes and litchis in Bihar and UP are particularly vulnerable to 70 km/hr winds. Next, the rainfall provides a boost to the upcoming Kharif sowing preparations. Thus, the agricultural sector is balancing the risks of storm damage against the benefits of soil moisture.

So the IMD is coordinating with state agricultural departments to provide localized advice. Meanwhile, the decrease in temperature will reduce the irrigation requirements for thirsty summer vegetables. Therefore, the 2026 weather pattern remains a critical factor for the national food supply chain.
