Elsewhere in the state, Gaya recorded the lowest of 2.7 degree Celsius with a maximum of 15.4 degree Celsius (8 degree below normal). Purnia and Bhagalpur registered a minimum of 6.0 and 6.1 degree Celsius and a maximum of 15.1 and 13.2 degrees Celsius respectively. Patna Met director A K Sen said, "Though the minimum temperature in the state capital recorded on Monday was 6.1 degree C, three degree C less than normal, the maximum was 9.7 degrees C, 13 degrees C below normal, leading to extreme cold. This spell will continue for at least another 24 hours. Once the moisture trapped at the mid-tropospheric level starts receding from Tuesday, the maximum temperature will rise but the minimum temperature will fall further." The northwesterly wind speed continues to be 8-9km per hour causing wind chill. Wind speed over 5km per hour leads to chill, added the Met director. Even sources in the Indian Meteorological Department, New Delhi, said cold wave condition will continue to prevail across Bihar. The cold has brought intense misery to the city's homeless, estimated to be around 30,000-35,000, who have no option but to sleep on the streets under the open sky as there are no night shelters for them in the city. However, the district administration claimed that adequate number of bonfires have been arranged at various localities to keep the shivering population warm. Both flights and train services were also badly hit on Monday. No flight could land at the Loknayak Jayaprakash Narayan airport due to extremely poor visibility (800 meters). Most of the trains passing through Patna junction and originating from north and north-east areas were running late by four to eight hours. Three trains - Sampoorna Kranti Express, Patna-New Delhi and Magadh Express - were rescheduled to leave Patna for New Delhi at 8pm and 9.30pm (on Monday night) and 1am (in the wee hours of Tuesday), respectively. District agriculture officer, Patna, Nitesh Kumar Rai said this winter spell is good for crops like wheat, tori and seasonal vegetables. However, if the spell continues for about a week, it will hit the growth of vegetables and fruit-bearing trees and the yield.
