TROPICAL WEATHER OUTLOOK

A strong tropical wave will continue to produce cloudiness, moderate to heavy showers, gusty winds and thunderstorms over the Windward Islands and areas further south during the next 24 hours. This system has a high chance of tropical cyclone formation and is likely to become a tropical depression within the next two days.  

At 5:00 pm today, the centre of Hurricane Fiona was located near latitude 25.6 North, longitude 71.5 West. Fiona is moving toward the north near 9 mph or 15 km/h away from the Eastern Caribbean and does not pose a threat to our region.   

A tropical wave associated with an area of low pressure located over the central tropical Atlantic is moving slowly westward. This system has a low chance of tropical cyclone formation during the next five days.

A third tropical wave is forecast to move off the west coast of Africa tomorrow. Some development of this wave is expected while it moves slowly westward over the eastern tropical Atlantic during the next five days.
