The Antigua and Barbuda Meteorological Service has issued an update on two developing systems in the Atlantic, urging the public to remain alert as conditions evolve.
System AL92 Showers and thunderstorms linked to disturbance AL92 in the central tropical Atlantic are showing signs of greater organisation. Forecasters say the system could strengthen into a tropical depression or storm within the next 24 to 48 hours as it tracks west-northwest to northwest at 10–15 mph. The probability of formation has been set at 90 per cent over both the next two days and the next week.
Eastern Tropical Atlantic Wave A separate tropical wave has emerged off the coast of Africa and is moving westward at 15–20 mph. Meteorologists believe gradual development is possible later in the week, though its chances of formation remain low in the short term — near zero over 48 hours, but rising to 20 per cent over seven days.
The ABMS said residents should monitor official forecasts closely as the peak of the hurricane season continues.
