Urgent – Immediate Broadcast Requested Excessive Heat Watch Antigua and Barbuda Meteorological Service
9:00 am Sunday 05 May 2024
Excessive Heat Possible for Antigua and Barbuda…Heat Watch in Effect 9:00 am to 4:30 pm until Saturday…
Heat Index or Feels-Like Temperature: 38 °C or 100 °F or higher.
Location: Antigua and Barbuda.
Timing: 9:00 am to 4:30 pm until Saturday.
Synopsis: Light winds and relatively high humidity will possibly allow for the heat index to rise to
excessive levels resulting in dangerously hot conditions.
The threat of health problems, for mainly sensitive people, could rise to, at least, moderate with the potential for significant impacts. 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.
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.
Sensitive groups: While extreme heat can put everyone at risk for heat illnesses, health risks are
greatest for the elderly, young children, 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.
Health implications: Heat illnesses (heat: stroke, exhaustion, fainting, cramps, rash and oedema) are
preventable, but they can lead to long-term health problems and even death.
Caution: If any symptoms of heat illness are present (such as dizziness or fainting, nausea or vomiting,
headache, rapid breathing and heartbeat, or extreme thirst) immediately move to a cool place and
drink liquids; water is best.
The most dangerous heat illness is heat stroke, with symptoms that
include complete or partial loss of consciousness or confusion and high body temperature. If caring
for someone with those symptoms, call 911 immediately. While waiting for help, cool the person
immediately by moving them to a cool place, applying cold water to large areas of the skin or clothing
and fanning the person as much as possible.
Everyone should stay alert and take precautions – stay cool and hydrated. Check on vulnerable family
members, friends and neighbours.
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.
Be prepared! This excessive heat watch will be updated accordingly, and a warning may be
required. Stay tuned to updates from the Meteorological Service through antiguamet.com, Twitter,
