It has been raining continuously in Sylhet for the last few days, including 130 mm rainfall in the three hours from 12 noon to 3 pm on Sunday.
The rain is expected to continue for at least five more days, the Met office said.
The water level of the rivers is increasing due to rain. There is a risk of flooding. However, so far the water of the river has not crossed the danger level anywhere in Sylhet.
Like the previous two days, there has been heavy rain in Sylhet since Sunday morning. As the day progressed, the rain increased.
Heavy rains led to waterlogging in different parts of Sylhet. Water even entered Sylhet MAG Osmani Medical College Hospital, but health services were not disrupted, authorities said. However, patients are suffering while commuting.
On Sunday afternoon, knee-deep water accumulated in every room on the ground floor of the college building. However, after the rain stopped in the afternoon, the water receded.
Shah Mohammad Sajib Hossain, assistant meteorologist at the Meteorological Department's Sylhet office, said sylhet received 111 mm rainfall from 6 am on Saturday to 6 am on Sunday. On Sunday, 122 mm of rain fell from 6 am to 12 noon and 130 mm from 12 noon to 3 pm. He said there is a possibility of rain in Sylhet for the next five days.
Nur Azizur Rahman, chief engineer of Sylhet City Corporation, said, "Sylhet received more than 100 mm of rain in just three hours today. It takes a while for this amount of rainwater to recede. So there has been waterlogging in some areas for a short time. However, after the rain stopped, the water receded."
