PATNA: Patna and several other places in the state received light to moderate showers on Friday and India Meteorological Department (IMD) has predicted fairly widespread rainfall in Bihar over the next three days.
A yellow warning has also been issued for heavy rainfall along with thunderstorm and lightning in the state on Saturday and Sunday.
Through yellow warning, the IMD alerts the authorities concerned to be watchful for extreme weather conditions.
The expected rainfall has been attributed to a cyclonic circulation over Jharkhand and neighbourhood.
According to the evening bulletin issued by IMD, the cyclonic circulation would meander over the same area over the next three days.
“Under its influence, fairly widespread to widespread rainfall along with isolated heavy falls, thunderstorm and lightning are very likely over most parts of east and adjoining central India, including Bihar, Jharkhand, Chhattisgarh, Odisha and east Madhya Pradesh during the next three days,” the IMD said.
A trough line was also passing from east Uttar Pradesh to northeast Bay of Bengal across the cyclonic circulation over Jharkhand and neighbourhood.
Weathermen said moisture incursion owing to the trough line would also augment rainfall in the region.
Shailendra Kumar Patel, a meteorologist at Patna Meteorological Centre, said the distribution and intensity of rainfall was more in south Bihar as compared to northern parts of the state in the last 24 hours.
Highest rainfall in the state was recorded at Triveni (82mm), while Patna received 19mm rainfall between 8.30am and 5.30pm.
Patel added the cyclonic circulation over Jharkhand and neighbouring areas is likely to cause thundershowers along with lightning at many places in the state over the next three days.
Southwest monsoon had entered Bihar through Purnia in north-eastern parts of the state on June 12, a day ahead of its schedule.
Light to moderate and up to heavy rainfall has been occurring across the state on most days following the onset, though a lull was observed earlier this week.
In fact, Bihar has received 136% excess rainfall in the monsoon season till date.
The state has received 285.2mm rainfall from June 1 to 25, while the normal rainfall for the same period is 120.6mm.
