A sudden hail-storm paralysed the city briefly and sent more than 25 people to hospitals with minor injuries on Wednesday. It also swept over many parts of the country, leaving two sisters dead in Narsingdi and around 30 injured in Barisal and Munshiganj.
The hail shower also caused extensive damage to mango buds and tender branches, shattered window panes and damaged makeshift structures across the country.
The storm fritter away within an hour leaving white hails and blown off tree leaves on rooftops and other places.  
Our Narsingdi correspondent adds two minor sisters were killed as a boundary wall collapsed on them in Noarpara in Madhabdi municipality.
The deceased were identified as Chumki Akther, 4, and her sister Bithi Akhter, 6, daughters of Abdul Halim of the area.
Witnesses said the wall fell on the two sisters around 1:00pm during the storm, leaving them dead on the spot.
Meanwhile, Amar Ekushey Book Fair was suspended briefly due to the damage to many of its stalls and water-logging on the fair ground. 
The rain had, however, been welcomed by the city dwellers as it had washed away accumulated dust and refreshed the city air.
Immediately after the rain, many residents were found outside their residences either picking up hail chips or assessing the damages to their property.
The social networking site Facebook was soon flooded with videos of the welcome shower.
As the rain began to fall commuters took shelter at various spots where possible but about 80 community health workers, who were observing a sit-in strike at the Central Shaheed Minar, failed to find any cover and got drenched in the rain.
Muzzammel Huq, Sub-Inspector of Dhaka Medical College Hospital Police Outpost, said that at least 14 of the strikers were admitted to the hospital with hail hit injuries.
The injured have been identified as Sanjida, 24, Aklima, 30, Sharif, 32, Sumon, 31, Mafizul, 32, Mahiuddin, 37, Akhter, 27, Rezaul Karim, 30, Faisal, 25, Mahmudul Alam, 25 and Habibur Rahman, 32.
Besides, 12 more people were admitted to the hospital with head injuries sustained by falling hails.
Meteorologist Bazlur Rashid said that a sudden warm weather at any place causes the air to climb upward rapidly.
"The air climbs up, which is called upward pressure. It touches cool weather in high altitudes and turns into storm bearing clouds but as it gains weight it breaks into rainfall," he explained.
The Met Office forecast rain or thunder shower accompanied by temporary gusty or squally wind is likely to occur at a few places over Khulna, Barisal, Chittagong, Dhaka and Sylhet Divisions and at one or two places over Rajshahi Division.
Weather may remain mainly dry with temporary partly cloudy sky elsewhere over the country.
Night temperature may fall slightly and day temperature may fall by 1 to 3 degree Celsius over the country.
