Cyclone Montha has moved further north-northwest and intensified into a severe cyclonic storm.
The Bangladesh Meteorological Department (BMD) issued a special bulletin stating the severe cyclone was centred about 1,290km southwest of Chattogram seaport, 1,250km southwest of Cox’s Bazar seaport, 1,140km southwest of Mongla seaport and 1,155km southwest of Payra seaport at 6am on Tuesday.
The Met Office said the system is likely to move further north-northwest and cross the coast in India’s Andhra Pradesh by the evening or night.
A low-pressure area had developed over the Bay on Friday. It later turned into a well-marked low and then a depression on the same day.
By Sunday morning, it had developed into a deep depression. After intensifying into a cyclonic storm on Monday, it strengthened further into a severe cyclonic storm.
According to the BMD, the maximum sustained wind speed is about 90kph within a radius of 64km of the cyclone centre, rising to 110kph in gusts or squalls. The sea near the cyclone’s centre remains rough.
Meteorologist Md Omar Faruk told bdnews24.com that although the cyclone has become severe, Bangladesh is unlikely to experience any significant impact from it.
“When the cyclone moves over land, its peripheral effects may cause light rainfall in the country’s western region,” he said.
In terms of intensity, the Met Office classifies cyclones into four categories:
• Wind speeds between 62 and 88km per hour -- cyclone.
• Wind speeds between 89 and 117km per hour — severe cyclone.
• Wind speeds between 118 and 219km per hour — cyclone with hurricane-force winds.
• Wind speeds of 220km per hour or higher — super cyclone.
Earlier this month, another cyclone named Shakti had formed over the Bay of Bengal, but it had little impact on Bangladesh.
The name Montha was given by Thailand and means “beautiful or fragrant flower”. Due to its influence, Chattogram, Cox’s Bazar, Mongla, and Payra seaports have been advised to keep distant warning signal No. 2 hoisted.
All fishing boats and trawlers over north Bay have been advised to remain close to the coast and proceed with caution until further notice.
They have also been instructed not to venture into the deep sea.
The BMD’s regular weather bulletin on Tuesday morning said that an associated trough of the cyclone extends up to the north Bay.
Between 9am Tuesday and the next 24 hours, some places in the Khulna, Barishal, and Chattogram divisions may experience rain or thundershowers, while weather elsewhere in the country is expected to remain mainly dry with partly cloudy skies.
Daytime temperatures are likely to remain nearly unchanged across the country, while nighttime temperatures may rise slightly.
During the past 24 hours, the highest temperature in the country was recorded at Patuakhali's Khepupara at 35.9 degrees Celsius, while the lowest temperature was reported at Naogaon’s Badalgachhi at 21.8 degrees Celsius.
