A fresh heatwave started on Tuesday with the forecasts of it continuing until the end of the week.
The return of the heatwave is rather unexpected as it goes against what Bangladesh Meteorological Department predicted on Monday that the rest of the month would remain comfortable with rain.
鈥楾he heatwave is likely to continue until May 25,鈥� said meteorologist Shaheenul Islam, predicting rain at the end of the week under the influence of a low pressure being developed over the Bay of Bengal.
On Tuesday, Bangladesh鈥檚 highest maximum day air temperature of 37.5C was recorded in Chuadanga.
The day air temperature in Dhaka increased by about 4C to 37.5C on Tuesday compared with the day before.
A mild heat wave is sweeping over Sylhet division and the districts of Dhaka, Netrakona, Chattogram, Rangamati, Feni, Cox鈥檚 Bazar, Bagerhat, Jashore and Chuadanga and it may continue and spread, the BMD said in its weather bulletin issued at 6:00pm.
Day and night air temperatures are likely to rise over the next few days, the BMD said, predicting a rise in discomfort because of moisture increased incursion.
The BMD predicted a low pressure to form over the southwest Bay of Bengal by today with chances of it intensifying.
India Meteorological Department said that the potential low pressure might turn into a depression over central Bay of Bengal by Friday morning.
The weather system is likely to intensify, the IMD said, indicating the likelihood of its turning into a cyclonic storm.
The IMD advised fishermen to come close to shore before Mat 23.
Bangladesh鈥檚 longest-ever heatwave lasted 37 days between March 31 and May 6. At least 15 people died from heatstroke during the heatwave after April 22.
During the longest heatwave, the country鈥檚 highest day temperature of 43.8C was recorded in Jashore on April 30, the hottest day in over three decades. Day temperatures frequently exceeded 40C in Dhaka, which saw its peak at 40.5C on April 30, the second hottest day in the capital in the past 64 years.
