Gaya has now recorded its highest 24-hour rainfall figure in last 10 years for the month of July. The all-time 24-hour rainfall record stands at 209.8 mm, dating back to July 27, 1886.
Though Monsoon covered Bihar on June 23, since then, Gaya received heavy rainfall on two occasions only. Heavy rains lashed the city on June 23 and June 26. In fact, most parts of Bihar remained devoid of good Monsoon rains since the onset of Monsoon in the region.
Only scanty rainfall was observed in the region in the month of July. Starting from the first week of July, till date, Bihar remains deficient in terms of rainfall and is running 32% below normal.
But now, as per Skymet Meteorology Division in India, moderate to heavy rainfall is likely to continue over most parts of Bihar for the next 3 to 4 days. These rains are a product of two cyclonic circulations which are being assisted by the axis of the Monsoon trough. One cyclonic circulation is currently over North Bay of Bengal and another feeble circulation can be seen over Bihar. The axis of Monsoon trough is passing through this system. Also, easterly winds from the Bay of Bengal are prominent over Bihar and adjoining northern plains.
The axis of Monsoon trough is also supported by a Western Disturbance which has now started affecting the northern parts of the country. After 3 days, the intensity of rainfall over Gaya and adjoining areas is expected to decrease. But even then, light to moderate scattered rain will continue over the region till July 12-13.
Meanwhile, heavy rain is also being observed over Nepal and more rain is expected in the region. This incessant rainfall activity in Nepal is likely to give birth to a flood like situation over northern parts of Bihar as the rivers Koshi, Narayani, and Bagmati flow from Nepal towards plains of Bihar. As a result, northern districts of Bihar are at a risk of being flooded.
