The heatwave this year is likely to hit the metropolis in the last week of May or first week of June, weather officials said.
Hundreds of fatalities resulting from the unprecedented heatwave last year were apparently due to a lack of coordination among various civic agencies.
Provincial health department has decided to set up heat stroke relief centres at government hospitals and emergency centres in various areas from May this year due to weather reports forecasting intense heat in May and June.
The temperatures rise due to abnormal weather patterns, high humidity, low air velocity and also dry wind, experts said. Around 65,500 people were brought to hospitals in Karachi last year during the heatwave, government officials said.
According to government sources, 1,233 people were died in Karachi in the heatwave. Experts advise establishment of heatstroke treatment centres at all hospitals and creating awareness of self-care and individual-level prevention from heat stroke.
