The Adverse Weather Alert
Even with abundant moisture and favorable atmospheric conditions, shower and thunderstorm activity has mostly remained to our east due to strong wind shear from the northwest and west. The ITCZ still remains across T&T, with the axis of Tropical Wave 58 now moving across the Lesser Antilles, and Tropical Wave 59 to our far east.
Models continue to show a favorable atmospheric setup for cloudy skies, showers, and thunderstorms through the weekend into next week. Severe thunderstorms are possible on Saturday, with heavy rainfall and strong winds likely across both islands.
