Odisha: Low-Pressure Area Over Bay of Bengal to Help Rainfall Deficit

While most of Northern India continues to get relief from the South West Monsoon winds in the form of heavy showers, monsoon winds over Odisha have become weak over time. Since the onset of the monsoon on June 10, the state has witnessed a 16% deficit in rainfall compared to earlier years.

The Indian Meteorological Department said that in the absence of rain, the heat and humidity had increased to uncomfortable levels over the region. However, it predicted the formation of a low-pressure area over the Bay of Bengal, which would bring in rainfall and the intensity of which would only increase as the week progresses.

“The monsoon started well in Odisha and later became subdued. So far, the state has recorded 16% less than normal rainfall. The monsoon has become weak due to several reasons. Low pressure likely to form on July 14 and 15. We are keeping a close watch on it. With this, rainfall activity is likely to increase. Usually, in July and August, maximum rain of the season occurs,” said HR Biswas, director of IMD’s Bhubaneswar Centre.

Biswas noted that since June 10, Odisha has received only 206.9 mm rainfall against the normal rainfall amount of 246.2 mm. Bhadrak, Keonjhar, Jajpur and Gajapati received around 40% less rainfall than normal. Eight districts have received deficit rainfall between 20% and 40%, while the rest 17 districts have got normal rainfall. Only Koraput has recorded excessive rainfall amongst the thirty districts of the state. However, on Saturday, rainfall picked up in the state, with Udala in Mayurbhanj district recording the highest of 91.4 mm.

“Troughs are responsible for clouding, rain and thundershowers apart from several other reasons for expediting the monsoon. If the trough moves in northern direction Odisha is likely to get more rain,” added Biswas.
