However the environment around its axis is relatively dry and expected to cross with little shower activity overnight into Thursday. Meanwhile, slight hazy conditions should be thinned with improved visibility.
A trough is expected across the Southern Windward Islands late Thursday followed by another tropical wave on Friday bringing scattered showers and possibly isolated thunderstorm activity.
The Atlantic High Pressure is expected to rebuild across our area by Saturday with hazy conditions, increased wind speeds and rising sea swells.
