Cyclone Mahasen is likely to hit the coastal areas of Bangladesh today.
The tropical storm may cross the Chittagong coast around midday, bringing heavy rain and eight to 10 feet high tidal waves in its wake, according to a Bangladesh Meteorological Department (BMD) bulletin issued last night.
The authorities have raised the danger level to seven, on a scale of 1 to 11, for Chittagong and Cox's Bazar ports.
Although not very strong, Mahasen is a very large storm, said Nasa in its website, adding that the storm would cause high tide and heavy rainfall.
Talking to The Daily Star, BMD Director Shah Alam could not predict whether Mahasen would be as severe as the 2007 super cyclone Sidr, but said it might have a maximum wind speed of 100km per hour during land fall.
The maximum wind speed at the storm centre is expected to be between 62 and 90kmph. The sea will remain rough near the storm centre.
The 2007 Sidr and the 1991 Chittagong cyclones were category-5 super cyclones, having up to 260kmph wind speed. The 1970 Bhola cyclone was a category-3 tropical cyclone with maximum 205kmph wind speed, while the 2009 Aila was a category-1 cyclone with maximum 110kmph wind speed.
At midnight last night, the BMD bulletin said, Mahasen was lying in the West Central Bay -- some 555km southwest of Chittagong Port, 500km southwest of Cox's Bazar Port and 445km south-southwest of Mongla Port.
