Excessive heat advisory in effect for Antigua and Barbuda
If you are in Antigua and Barbuda and the weather feels warmer than usual, that’s because an extreme heat advisory is in effect until Sunday.

The threat of health problems is moderate, for mainly sensitive people. An excessive heat advisory is issued within 12 hours of the onset of hot conditions.
The threshold for this advisory is when the maximum heat index temperature is expected to be in the range of 38 to 41 °C or 100 to 106 °F, for any length of time, for two or more consecutive days, with the winds 18 km/h (11 mph) or less.
While extreme heat can put everyone at risk for heat illnesses, health risks are greatest for the elderly, young children, people with chronic diseases such as breathing difficulties, heart conditions or psychiatric illnesses, people who work or exercise in the heat, homeless people and low-income earners.
Some heat illnesses, including heat: rash, edema, syncope/fainting, cramps, exhaustion and stroke. Heat illnesses can lead to long-term health problems, and heat stroke can lead to death.
