The Antigua and Barbuda Meteorological Service has issued an Excessive Heat Watch, warning residents of potentially dangerous weather conditions in the coming days.

The watch, which remains in effect until Friday, indicates that the heat index could reach alarming levels, posing significant health risks to the population.

According to the Met Office, the heat index, also known as the “feels-like” temperature, could climb to 38°C (100°F) or higher. The watch is in effect daily from 10am to 4pm, covering the hottest part of the day.

“Light winds and relatively high humidity will possibly allow for the heat index to rise to excessive levels resulting in dangerously hot conditions,” the Met Office stated in their advisory.

They further explained that “the risk of health problems, for mainly sensitive people, could rise to medium.”

The meteorological authorities emphasized the uncertainty of the exact onset of these extreme conditions. “An excessive heat watch is issued when conditions are conducive for an excessive heat event in the next 24 to 72 hours; however, the timing is still uncertain, and it is not guaranteed,” they clarified.

The Met Office outlined specific criteria for issuing such a watch, noting that “The threshold heat index temperature for a watch is 38°C (100°F) or higher, for two or more consecutive days, with the winds usually being 18 km/h or 11 mph or less.”

Health officials are particularly concerned about vulnerable groups. The Met Office warned, “While extreme heat can put everyone at risk for heat illnesses, health risks are greatest for the elderly, young children, lactating mothers, people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses, people who work or who exercise in the heat, homeless people and low-income earners.”

The advisory also detailed potential health implications, stating, “Heat illnesses (heat: stroke, exhaustion, fainting, cramps, rash and edema) are preventable, but they can lead to long-term health problems and even death.”

Residents are urged to stay alert and take precautions. The Met Office advises, “Everyone should stay alert and take precautions – stay cool and hydrated. Check on vulnerable family members, friends and neighbours.”

They also recommend that “Those who take medication or have a health condition should ask their doctor if it increases their health risk in the heat and follow their recommendation.”

In case of heat-related symptoms, the public is advised to “immediately move to a cool place and drink liquids; water is best.”\ For severe cases, especially those showing signs of heat stroke, the advisory is clear: “If caring for someone with those symptoms, call 911 immediately.”

As Antigua and Barbuda face this potential heat wave, authorities stress the importance of community awareness and mutual support to ensure everyone’s safety during these challenging weather conditions.
