Patna, September 24: Bihar is likely to witness another spell of rain and thunderstorms from September 25 to 27, with the India Meteorological Department (IMD) issuing warnings for heavy rain, lightning and strong winds across parts of the state.
According to the IMD’s September 24 warning bulletin, heavy rain along with thunderstorm and lightning activity is expected on September 25 and 26. Thunderstorm and lightning activity is also forecast for September 27.
The latest alert comes after a change in weather conditions across Bihar, with rain reported in several areas. The unsettled weather is expected to continue over the next few days.
Bihar Weather Forecast For September 25
On September 25, IMD has forecast heavy rain along with thunderstorms and lightning in Bihar. Strong winds are also likely in some areas.
The district-wise forecast provided in the source material indicates that East Champaran, West Champaran, Sitamarhi, Sheohar and Gopalganj are among the districts that could receive heavy rainfall.
Several other districts may also experience rain and thunderstorms during the day.
Heavy Rain Warning For September 26
The rainy conditions are expected to continue on September 26, when IMD has again issued a warning for heavy rain, thunderstorms and lightning in Bihar.
According to the source forecast, East Champaran, Gopalganj, Siwan and Saran are among the districts facing the possibility of heavy rainfall.
Strong winds of around 40–50 kmph are also expected in affected areas, according to the forecast provided in the source material.
Thunderstorm And Lightning Alert On September 27
On September 27, IMD has forecast thunderstorm and lightning activity across Bihar.
The source forecast identifies East Champaran and West Champaran as areas that could continue to see unsettled weather and heavy rain.
A yellow alert has also been indicated for Sitamarhi, Sheohar, Gopalganj, Siwan, Aurangabad, Bhojpur, Buxar, Darbhanga, Madhubani, Kaimur and Samastipur, among other districts.
Weather System Behind The Rain
The latest spell of rain is associated with a weather system over the Bay of Bengal, which has increased rainfall activity over eastern India.
According to the source material, the system was located over the west-central and adjoining northwest Bay of Bengal on September 23 before moving west-northwestwards towards the Andhra Pradesh and Odisha coast.
The system and associated weather conditions have contributed to increased moisture and rainfall activity over Bihar and neighbouring parts of eastern India.
Patna Also Likely To Receive Rain
Patna is also expected to remain cloudy with rain or thundershowers during the period.
The latest IMD forecast for Patna Airport shows generally cloudy conditions with one or two spells of rain or thundershowers on September 25 and 26. Similar conditions are forecast for September 27.
The IMD’s Patna warning issued earlier also indicated strong gusty winds and thunderstorms with lightning, including winds of 40–50 kmph on September 25.
Temperature May Dip
The continued rainfall could lead to a fall in temperatures across parts of Bihar.
The source forecast indicates that temperatures could decline by around 2–4 degrees Celsius in some areas during the rainy spell.
With thunderstorms and lightning expected, residents have been advised to follow official weather warnings and avoid exposed areas during severe weather.
IMD Forecast Beyond September 27
The current Bihar-wide IMD warning bulletin does not list a warning for September 28 to 30, although local forecasts can change as weather systems evolve.
For now, the main weather concern remains the three-day period from September 25 to 27, with heavy rain expected on the first two days and continued thunderstorm and lightning activity on September 27.
