Chhattisgarh Weather Tracker 2026: Rain activity is set to remain strong across the state on Thursday, August 20, with the India Meteorological Department (IMD) warning of heavy rainfall at isolated places and thunderstorms with lightning. The weather system moving across the region is expected to keep monsoon conditions active through the next several days.

LAST UPDATED: 20 August 2026 | 8:47 AM IST

1. Rain Alert Across State

Chhattisgarh is likely to witness widespread monsoon activity today. The latest IMD bulletin says fairly widespread to widespread rainfall is likely over Chhattisgarh on August 20, with another spell expected during August 23-25. Thunderstorms and lightning are also likely between August 20 and 23.

The weather department has also indicated that isolated heavy rainfall could continue in the state as the prevailing weather system moves west-northwestwards across the region. An IMD national bulletin issued on August 19 said light to moderate rain was expected at most places in Chhattisgarh, with heavy rainfall likely at isolated places through August 21.

2. Lightning Risk Remains

Thunderstorm and lightning activity will remain an important concern today. The latest IMD forecast places Chhattisgarh under a thunderstorm and lightning outlook for August 20-23.

People in open fields, agricultural areas and other exposed locations should avoid unnecessary outdoor activity when thunder is heard. Residents should move indoors before lightning activity intensifies and avoid standing beneath isolated trees or near water bodies.

The risk can vary sharply from one district to another, so local warnings should be followed rather than assuming that conditions will remain the same across the entire state.

3. Raipur Weather Watch

The state capital Raipur is likely to remain under cloudy and humid conditions, with rain possible during the day. The broader weather pattern indicates that the capital and surrounding areas can continue to experience intermittent showers as the monsoon system remains active.

The possibility of rain may affect traffic movement, particularly during intense spells. Reduced visibility, water accumulation on roads and sudden thunderstorms can create short-duration disruptions.

4. Weather System Behind Rain

The current spell is linked to an active weather system over central and adjoining parts of India. IMD's August 19 national bulletin said the system was expected to continue moving west-northwestwards across southeast Uttar Pradesh, adjoining north Chhattisgarh and northeast Madhya Pradesh during the following 24 hours.

The system's movement is supporting continued moisture and rainfall activity over Chhattisgarh. This is why the state is likely to see another round of rain even as the intensity varies between districts.

IMD's latest forecast also indicates that rainfall activity will not completely disappear after August 21, with another fairly widespread to widespread spell possible around August 23-25.

5. Temperature and Humidity

Persistent cloud cover and rain are expected to keep daytime temperatures relatively moderated across several parts of Chhattisgarh. However, high atmospheric moisture can make conditions feel humid between showers.

The temperature pattern will depend on the duration of cloud cover and rainfall at individual locations. A prolonged rain spell can temporarily lower daytime temperatures, while breaks in rainfall may quickly increase humidity and discomfort.

For residents, the combination of humidity, intermittent rain and thunderstorms means conditions can change quickly during the day.

6. Waterlogging and Farm Risk

Periods of heavy rain can cause temporary waterlogging in low-lying areas and affect traffic on poorly drained roads. Localised runoff may also increase the water level of smaller streams and drains.

The agricultural impact will depend on how much rain individual areas receive. Regular monsoon rain can support kharif crops, but prolonged waterlogging can become a concern for fields with inadequate drainage.

An earlier IMD flash-flood assessment had identified several Chhattisgarh districts, including Koriya, Surajpur, Balrampur, Jashpur, Korba, Surguja, Bilaspur, Bemetara, Baloda Bazar, Mungeli and Raipur, as areas where low-to-moderate flash-flood risk had occurred during an earlier heavy-rain spell. That assessment was for August 15 and should not be treated as today's district warning, but it highlights the need for caution in saturated and low-lying areas.

7. August 21-25 Forecast

Rainfall activity is expected to continue beyond Thursday. IMD has forecast heavy rainfall at isolated places in Chhattisgarh through August 21, while fairly widespread to widespread rainfall is expected again during August 23-25. Thunderstorms and lightning are forecast during August 20-23.

This means residents should remain prepared for intermittent rain, thunderstorms and lightning over the coming days. Travel plans may need adjustment during intense spells, particularly in areas prone to waterlogging.

The exact intensity and timing of rain will vary by district. People should therefore check the latest IMD district or nowcast warning before travelling, especially when thunderstorms are developing nearby.

Today's Weather Conclusion: Chhattisgarh remains under an active monsoon pattern on August 20. Rain, thunderstorms and lightning are the main weather concerns today, with isolated heavy rain possible. The weather is expected to remain unsettled through the next several days, with another significant rainfall spell possible around August 23-25.
