High tide floods low-lying districts
The lowlands and char areas several coastal districts have been flooded due to the combined effect of impending super cyclone Yaas and full moon tidal wave increasing water levels of rivers.
Around 3 lakh people in Bhola are reportedly being evacuated by the coast guard as nearly 40 chars areas under seven upazilas have been marked as unsafe under the looming threat of cyclone Yaas.
Bhola Deputy Commissioner Toufiq-E-Elahi Chowdhury confirmed the matter at the virtual preparatory meeting for cyclone Yaas on Tuesday.
