The effects of Cyclone Mora gone, the heat is back to torment Patna residents.
Following a short spell of thunderstorm and rain, courtesy the cyclone, Patna's temperature is on the rise since Thursday. The trend will continue for the next four-five days as warm westerlies are currently blowing over the region.
The Met department said this phenomenon will continue more or less till the arrival of monsoon which is expected to break in Bihar around mid June.
"Hot westerly winds blowing over the state has resulted in a rise in the temperature, all along Bihar to Rajasthan," said Patna Met director Sumendu Sengupta. "Isolated showers, arising out of some local factors, however, cannot be ruled out."
Apart from isolated rain if any, there will not be any respite from the scorching heat, the weather chief in Patna said. "Temperatures will only come down once the southwest monsoon hits the state," he said.
The southwest monsoon is expected to hit Bihar around June 15.
"The relief has disappeared. There's more heat. I believe this is because of the city's growth," said Ankit Raj, a budding entrepreneur in Patna. "Increasingly, there are more inhabited areas and less of green space. The government must make more green areas, put an environmental law in place that would stop the community from destroying the few remaining tress in the urban landscape."
According to private weather agency Skymet Weather, Bihar and Jharkhand has been witnessing on and off rains. Dry weather conditions will now make a comeback over east Uttar Pradesh, Bihar and Jharkhand in the next three-four days, the agency said.
After a brief break, pre-monsoon rains is expected to start over Bihar, Jharkhand and Bengal around June 6, Skymet predicted. Intensity of the rain will increase over many parts of east India, with a few good spells over Bihar, Uttar Pradesh, sub-Himalayan Bengal around June 7 or 8.
The India Meteorological Department in its Friday weather forecast also said thunderstorm accompanied by gusty winds is very likely to occur in isolated places over east Bihar.
It said that a north-south trough - running from Bihar to north Chhattisgarh across Jharkhand and extending up to 0.9km above mean sea level - has resulted in the sudden change in weather.
The initial reason behind the rise in temperature since Thursday when the maximum temperature touched 40°C, the weather department said, was the trough from West Rajasthan to Bihar across Uttar Pradesh extending up to 0.9km above mean sea level had become less marked.
The Met department has said the maximum temperature is very likely to rise by 2-3°C over Bihar, Rajasthan, Jharkhand and inner Odisha in the next 72 hours.
