According to BMD, the low-lying areas of the coastal districts of Cox's Bazar, Chittagong, Noakhali, Lakhmipur, Feni, Barguna, Bhola, Patuakhali, Bagherhat, Khulna, Satkhira and their offshore islands and chars are likely to be inundated by wind-driven surge of 3-5 feet above normal astronomical tide due to the peripheral effect of the cyclone and steep pressure gradient.
Under the influence of the cyclone, Dhaka, Khulna, Barisal, Chittagong and Sylhet divisions are likely to experience heavy (44-88mm) to very heavy (289mm) rainfall.
And due to very heavy rainfall, landslides may occur at places over the hilly regions of Chittagong Division, according to the BMD bulletin.
