Weather Update: The National Hurricane Centre is issuing advisories on Hurricane Fiona, located northeast of the south-eastern Bahamas, and on Tropical Storm Gaston, located over the north-central Atlantic Ocean.
1. Western Tropical Atlantic:
A tropical wave is producing shower and thunderstorm activity a couple of hundred miles east of the southern Windward Islands. The system continues to show signs of formation and is likely to become a tropical depression within the next couple of days. Expectedly, the tropical disturbance will move west-north-westward across the southern Windward Islands today and then move toward the central Caribbean Sea later this week. Interests in the Windward Islands would be closely monitoring the progress of this system as heavy rainfall and gusty winds are affecting these islands. As per the forecast, regardless of development, heavy rainfall will affect north-western Venezuela, north-eastern Colombia, and the ABC island chain later this week. It has a high (70 percent) chance of formation during the next 48 hours and a high (90 percent) chance in the next five days.
2. Eastern Tropical Atlantic:
A tropical wave is forecast to move off the west coast of Africa on Thursday. Thereafter, environmental conditions are forecast to be conducive for some development, and a tropical depression could form this weekend while the system moves slowly northward between west Africa and the Cabo Verde Islands. It has a low (20 percent) chance of building during the next two days (48 hours) and a medium (50 percent) chance in the next five days.
3. East Central Tropical Atlantic:
Shower and thunderstorm activity has increased in association with a tropical wave located several hundred miles west-southwest of the Cabo Verde Islands. Despite a dry environment, slow development of this system is possible over the next several days as it moves north-westward and then westward over the tropical Atlantic. It has a low, around 20 percent, the chance of formation during the next 48 hours and a low (30 percent) chance in the next five days.
