Between June-September, rain-related incidents claimed 458 lives in Jharkhand

**Rain-Related Incidents in Jharkhand Claim 458 Lives Between June and September**

*By Chanshimla Varah | October 9, 2025, 5:19 PM*

Jharkhand has witnessed its worst monsoon in a decade, with heavy rains from June to September claiming at least 458 lives. The season’s severe weather not only led to tragic fatalities but also caused extensive damage to homes and farmlands across the state.

**Casualties and Causes**

According to official data, lightning strikes were responsible for the deaths of 186 people, while 178 others drowned in various rain-related incidents. Additional casualties resulted from floods, landslides, and house collapses triggered by the intense rainfall.

**Impact on Housing and Agriculture**

The monsoon devastation extended beyond loss of life. A total of 467 houses were completely destroyed, and over 8,000 others suffered partial damage. Farmlands were severely affected as well, with crop losses reported across 2,390 hectares in districts such as Ranchi, Gumla, Lohardaga, and Simdega.

In Sahibganj district, rising water levels in the Ganga River displaced approximately 20,000 people, further highlighting the season’s widespread impact.

**Record-Breaking Rainfall**

The Ranchi Meteorological Centre recorded a total rainfall of 1,199.5 mm between June 1 and September 30 this year, marking an 18% increase over normal levels. Abhishek Anand, director of the center, explained that this was the highest rainfall the region has experienced in a decade. He attributed the unusual intensity to climate change and rising sea surface temperatures in the Bay of Bengal.

**Districts Most Affected**

Unusual meteorological activity in the Bay of Bengal contributed to repeated heavy downpours, especially in eastern and southeastern parts of Jharkhand. East Singhbhum recorded the highest rainfall at 1,669.5 mm, followed closely by Ranchi with 1,550.2 mm and Saraikela-Kharsawan at 1,526.3 mm. Each of these districts received more than 50% above normal rainfall for the season.

**Weather Outlook**

The India Meteorological Department (IMD) has forecasted a “pink cold” or mild winter around Diwali and Chhath Puja celebrations. However, the severity of the upcoming winter season will depend on global factors such as the La Niña phenomenon and shifts in wind patterns.

While rainfall activity is currently declining, isolated moderate rain showers accompanied by thunder and lightning are expected to continue until October 12. Following this period, dry conditions are anticipated as the monsoon gradually withdraws.

Stay tuned for updates and precautionary advisories as the season progresses.

IND W vs SA W, ICC Women’s World Cup 2025 Weather Update: Rain Delays Start In Vizag, What Happens If The Match Gets Abandoned?

India are gearing up for a crucial third group-stage encounter in the ICC Women’s World Cup 2025 against South Africa at the ACA-VDCA Stadium in Visakhapatnam on Thursday, October 9th. Having won both their opening matches, India will be aiming for a dominant performance to strengthen their position as favourites to win the title.

### Weather Concerns Could Impact the Match

However, weather conditions are currently posing a major hurdle. According to AccuWeather, there is a significant chance of rain during match hours, with a 49–58% likelihood between 4 pm and 6 pm. While a complete washout is not certain, rain delays and reduced overs are possible.

The toss could also be affected, as the city witnessed rainfall around 3 pm just a day before the match, and similar conditions are expected today. With rains currently pouring, there is no update on when the match would start.

### What Happens If the India Women vs South Africa Women Match Gets Washed Out?

If the rain results in the match being washed out, it is important to note that there is no reserve day for group-stage fixtures in the Women’s World Cup. This means both India and South Africa will be awarded one point each.

### India Women vs South Africa Women Head-to-Head

These two sides have played against each other frequently in recent times. While South Africa have come close on several occasions, India have come out on top in their last five encounters. However, in a World Cup setting, a rejuvenated South African side will be eager to turn the tables.

### Squad Updates

**India Squad:**
Harmanpreet Kaur (C), Smriti Mandhana, Pratika Rawal, Harleen Deol, Jemimah Rodrigues, Richa Ghosh, Deepti Sharma, Amanjot Kaur, Radha Yadav, Kranti Gaud, Renuka Singh, Arundhati Reddy, Sneh Rana, N. Shree Charani, Uma Chetri.

**South Africa Squad:**
Laura Wolvaardt (C), Tazmin Brits, Sune Luus, Marizanne Kapp, Anneke Bosch, Sinalo Jafta (WK), Chloe Tryon, Nadine de Klerk, Masabata Klaas, Ayabonga Khaka, Nonkululeko Mlaba, Annerie Dercksen, Nondumiso Shangase, Karabo Meso, Tumi Sekhukhune.

Stay tuned for live updates as the match unfolds amidst challenging weather conditions.

Bengaluru Weather Update: IMD Issues Alert In These Regions Of Karnataka; Check Details

**Bengaluru Weather Update: Moderate to Heavy Rainfall Expected on October 8, 2025**

Bengaluru, the capital city of Karnataka, is set to experience moderate to heavy rainfall on Wednesday, October 8, 2025. Cloudy skies are also expected throughout the day, creating a mild and pleasant atmosphere for residents.

The city woke up at 6:09 AM, with minimum and maximum temperatures forecasted to range between 21°C and 27°C respectively. The sunset is expected at 6:09 PM.

According to the Karnataka State Natural Disaster Monitoring Centre (KSNDMC), which shared a detailed seven-day weather report on X (formerly Twitter), scattered light to moderate rain accompanied by strong winds and thundershowers will be widespread across the state. Coastal, Malnad, and South Interior districts are likely to experience heavy rainfall from today through October 12.

**Today’s Air Quality and Humidity**

Humidity levels in Bengaluru are expected to hover around 88%, contributing to the overall moisture in the air. The Air Quality Index (AQI) is forecasted to be approximately 30, indicating good air quality across the city and surrounding areas. This AQI level is expected to remain stable throughout the day.

**IMD Advisory**

The India Meteorological Department (IMD) has issued an advisory warning that the rainfall may cause temporary disruptions to electricity supply. There is also a possibility of minor traffic snarls and the uprooting of weak tree branches due to strong winds.

Residents are advised to stay indoors and ensure that windows and doors remain closed to stay safe during these weather conditions.

**About the Southwest Monsoon**

The Southwest Monsoon is a seasonal wind shift bringing heavy rainfall to South Asia, particularly India, from June to September. This monsoon period is characterized by a reversed wind pattern, with winds blowing from land to sea and vice versa, carrying moisture that results in significant rainfall.

Stay tuned for further updates and take necessary precautions to stay safe in the coming days.

India’s Above-Normal Monsoon Brings Mixed Fortunes For Kharif Crops; Excess Rainfall Damages Paddy, Pulses, Cotton

The southwest monsoon 2025 commenced its withdrawal by mid-September. It is now time to evaluate its performance and examine the harvest prospects of key crops across the country.

### Rainfall Overview

The good news is that, as forecast by the India Meteorological Department (IMD), India has enjoyed above-normal rainfall this season. Between June 1 and September 27, the country received 922 mm of rainfall, which is 8 percent above the normal level.

However, the distribution of rainfall was uneven. While east and northeast India—mainly Bihar and Assam—suffered a 19 percent rainfall deficiency, the northwest regions, primarily Punjab and Rajasthan, experienced a 28 percent surplus. Central India received 13 percent above-normal rainfall, and the southern peninsula saw an 11 percent surplus.

### Impact on Agriculture

Although the total quantum of rainfall during the season is important, the temporal and spatial distribution is critical for agriculture. August and September witnessed excessive precipitation in some parts of the country such as Punjab, Maharashtra, Karnataka, and Rajasthan. This has reportedly inflicted crop damage.

There have been reports regarding adverse impacts on paddy and pulse crops, but the full extent of damage is still under assessment. Anecdotal evidence also suggests that excessive rains have impacted crop quality.

Below is an assessment of the likely harvest size of key Kharif crops. The forecast production numbers are presented as ranges, with planted area data as of September 26.

### Rice

The production target for rice this season is 123 million metric tonnes (MMT). The normal planted area, based on a five-year average, is 40.3 million hectares (ml ha). This year, the planted area was slightly higher at 44.2 ml ha, compared to last year’s 43.6 ml ha.

The rice crop is estimated to yield between 123 and 125 MMT, up from 121.8 MMT in 2024. Rice stocks in the country remain well above the buffer norm, and export restrictions have been lifted.

### Maize

The production target for maize is 26 MMT. Planted area expanded significantly this season to 9.5 ml ha, up from 8.8 ml ha last year, following increased demand for ethanol production driven by the government’s biofuel blending programme.

The maize harvest is expected to be in the range of 26 to 27 MMT, higher than the 24.8 MMT produced during the last Kharif season.

### Pulses

This protein-rich legume has faced challenges this year. The production target was reduced from 9.5 MMT in 2024 to 8.0 MMT in 2025. Planted area has also declined by one million hectares to 12.0 ml ha, down from a five-year average of 13 ml ha, as growers shifted to more remunerative crops like maize due to poor returns.

Despite satisfactory initial rains, excessive rainfall in August in pockets of Maharashtra and Karnataka damaged crops. Consequently, production is expected to decline to between 6.7 and 7.0 MMT, well below even the reduced target.

To augment availability and keep prices in check, imports of pigeon pea (tur/arhar) and black matpe (urad) have been allowed duty-free until March 2026.

### Oilseeds

Key Kharif oilseeds include soybean and groundnut, along with smaller quantities of sesamum, niger seed, sunflower seed, and castor seed.

The soybean planted area has decreased to 12 ml ha this season, down one million hectares from last year. However, satisfactory rainfall over the soy belt in Madhya Pradesh, Vidharba in Maharashtra, and parts of Rajasthan is expected to result in decent yields.

Soybean production is forecasted between 12.0 and 12.5 MMT, falling significantly short of the 16.2 MMT target. It is widely recognized that the government’s 2024 estimate of 15.2 MMT was overstated by 15 to 20 percent. Effectively, soybean production has seen little change.

In the case of groundnut, the main growing region of Gujarat received excellent rainfall, likely leading to improved yields. The overall production size is projected to be between 11 and 12 MMT, higher than the target of 10.5 MMT and last Kharif’s 10.4 MMT.

### Cotton

Cotton, a multipurpose crop used for fibre, food, and feed, has been losing acreage over the past three years. This season, the planted area has decreased to 11.0 ml ha, down from 11.3 ml ha last year and well below the five-year average of 12.9 ml ha.

Excessive rains in key cotton-growing states such as Maharashtra, Andhra Pradesh, Telangana, and Punjab, coupled with pest infestations, have resulted in crop losses. The government revised the production target down from last year’s 35 million bales (170 kg each) to 33.5 million bales for 2025.

Despite this, the harvest is estimated to be between 29.5 and 30.5 million bales, falling short of even the reduced target. Last year, production stood at 30.7 million bales. Crop quality is also likely to be compromised.

India has now become a net importer of raw cotton, and free imports are allowed until December 31, 2025. For 2025-26, imports are forecast at 3.5 to 4.0 million bales.

### Sugarcane

Sugarcane planted area has steadily expanded and stands at 5.9 ml ha for the 2025-26 sugar year, up from 5.7 ml ha last year and the five-year average of 5.2 ml ha.

Compared with the cane production target of 469 MMT and the 2024 production of 450 MMT, this year’s output could decline to between 440 and 460 MMT due to excessive rainfall in growing areas of Maharashtra and Karnataka.

The government has lifted the December 2023 restriction on diverting cane for ethanol production. After accounting for this diversion, sugar production in 2025-26 is likely to be around 30 MMT, slightly less than last year.

### Looking Ahead

Rains continued in southern and western parts of the country through the end of September, potentially causing more damage and delaying damage assessments. However, the continuing rains are expected to improve soil moisture, benefiting the Rabi planting season, including major crops such as wheat, rapeseed/mustard, and chickpea, which typically commence in late October.

Reservoir storage levels are satisfactory and higher than last year’s, providing a positive outlook for irrigation.

Given the combined production prospects of Kharif crops, ample public stocks of wheat and rice with government agencies, and a liberal import policy for pulses and edible oil, the risk to food inflation is tilted not to the upside, but potentially to the downside.

If Rabi crop prospects prove satisfactory, food prices may remain consumer-friendly. Nevertheless, weather conditions in the coming months will be a critical factor to watch.

**Note:** Except for the forecast of Kharif 2025 crop production (based on G. Chandrashekhar’s proprietary research), all data—including acreage, rainfall, and production targets—are official government figures.

Mumbai Weather Update: City Wakes Up To Sunny Skies, No Rain Alert Issued For Today

Mumbai Awakens to Clear Skies After Days of Relentless Showers

Mumbai woke up to cloudy skies in the early hours of Friday. However, the clouds soon disappeared, leaving behind clear skies and a sunny atmosphere. After days of relentless showers that battered the Konkan belt throughout September, residents finally experienced stable weather conditions.

The India Meteorological Department (IMD) has issued no alerts for any district in the region today, bringing much-needed respite for citizens.

Weather Forecast for Mumbai & MMR

In Mumbai, conditions remained dry through the morning, with temperatures expected to hover between 26°C and 31°C. While the absence of rainfall provided relief from waterlogging and traffic snarls, the combination of heat and high humidity made the day feel warmer than the actual temperature.

Neighbouring Thane and Navi Mumbai also reported a drop in rainfall intensity. Throughout September, residents in these cities struggled with disrupted daily routines due to frequent heavy showers and water accumulation in low-lying areas.

On Friday, however, the skies were only partly cloudy, accompanied by mild breezes. The weather in these cities is comparatively pleasant, with temperatures forecast between 27°C and 30°C. With no threat of heavy rainfall, citizens can step out without fear of disruption.

Conditions in Palghar District

In Palghar district, which bore the brunt of heavy monsoon showers last month, the situation has also eased. Rural areas continued to see intermittent drizzle under cloudy conditions, but urban regions mainly dealt with humid weather and rising heat.

Maximum temperatures may touch 30°C, while the minimum is expected at 25°C.

Weather Along the Konkan Coast

Further down the Konkan coast, districts like Raigad, Ratnagiri, and Sindhudurg have witnessed a break from intense rain. After widespread flooding in September, the climate turned calmer this week.

Ratnagiri and Sindhudurg recorded light winds that brought relief, while in Raigad, partly clear skies and a cool breeze along the coastline created more comfortable conditions for residents.

Temperatures in these districts are expected to range between 26°C and 30°C.
