Bhubaneswar: Amid thunderstorm activity, which is likely to continue in Odisha till October 10, a fresh cyclonic circulation/low-pressure may form over the north Bay of Bengal in the second half of this week, according to the India Meteorological Department (IMD).
Director of Bhubaneswar Meteorological Centre Manorama Mohanty stated that the strength and trajectory of the new weather system will become clearer in the coming days. “We are actively tracking the weather to determine details, including any potential impact on Odisha,” she added.
According to IMD’s extended rage outlook, IMD-GFS model is indicating the development of an upper air cyclonic circulation over north Andaman Sea around October 5 with north-northwestwards movement towards north Bay of Bengal and formation of a low-pressure area over north Bay of Bengal around October 9. “IMD-GFS model is also indicating the development of a low-pressure area over north Bay of Bengal around October 7. Bharat Forecast System is indicating development of a low-pressure area over northwest Bay of Bengal around October 10. NCEP-GFS is also indicating development of a cyclonic circulation/low pressure over north Bay of Bengal around October 9. NCUM (G) is also indicating development of a low-pressure area over north bay of Bengal around October 10,” it further stated.
ECMWF Sub-seasonal forecasts are not indicating any cyclogenesis probability during October 6-20, it added.
The fresh weather system may also delay withdrawal of monsoon this year. The southwest monsoon usually withdraws from the state between October 10 and 15.
Notably, 15 low pressure areas have formed during the ongoing southwest monsoon season and triggered heavy rainfall activity across Odisha since June 1.
Meanwhile, the weather agency has issued a yellow warning of thunderstorm accompanied by lightning and gusty surface wind speed reaching 30-40 kmph for one or two places in the districts of Sundargarh, Jharsuguda, Bargarh, Sambalpur, Deogarh, Angul, Dhenkanal, Keonjhar, Mayurbhanj, Balasore, Bhadrak, Jajpur, Kendrapada, Cuttack, Jagatsinghpur, Puri, Khurda, Nayagarh, Ganjam and Gajapati on October 7-8.
Similar weather conditions may prevail in Keonjhar, Mayurbhanj, Balasore, Bhadrak, Jajpur, Kendrapada, Cuttack, Jagatsinghpur, Puri, Khurda, Nayagarh, Ganjam and Gajapati districts during the subsequent two days.
According to the MeT office, moisture availability is triggering thunderstorm activity in parts of the state. Light to moderate rain may also occur at a few places across the state during this period as a trough also persists from north coastal Odisha to east Telangana across Interior Odisha and south Chhattisgarh, along with a cyclonic circulation over northeast Jharkhand & neighbourhood.
