A spell of hot and humid weather will prevail in Kolkata over the next few days.
The Met office on Wednesday issued a yellow warning for the rest of the week.
According to a special bulletin, dry westerly to northwesterly winds at lower levels are likely to push up temperatures and humidity across south Bengal, including the city. Day temperatures are expected to rise gradually by 4 to 6˚C over the next four days, and remain around 3 to 5˚C above normal.
In Kolkata, conditions are likely to remain dry through this period, with no immediate rain. The combination of rising temperatures and high moisture levels in the air is expected to make conditions uncomfortable, especially during the afternoon hours.
Humidity levels could range between 70 and 80 per cent in the districts, while coastal areas may see even higher values. The weather office has warned that such conditions may lead to discomfort and minor health issues, particularly among infants, the elderly and those with existing ailments.
Residents have been advised to avoid prolonged exposure to the sun between 11am and 4pm and to stay hydrated.
Relief in the form of light to moderate rain or thundershowers is likely only later in the week.
