Met Office monitoring four weather systems

The Trinidad and Tobago Meteorological Association said it is monitoring the development of four weather systems, one of which may affect Trinidad and Tobago this weekend.

In an update to social media on Thursday, the Met Office said three tropical waves and a system labelled Invest Area 95L are moving through the Atlantic.

Closest to Trinidad and Tobago is Tropical Wave 1, which was expected to pass over the Lesser Antilles on Saturday. An overview of the systems is as follows: 

Tropical Wave labelled 1 (closest to T&T)

Slow-moving Tropical wave whose axis is expected to pass over the Lesser Antilles on Saturday. 

Most of the activity is expected over the Leeward Islands, with indirect local effects on T&T.

As it moves westward, it will encounter unfavourable upper-level conditions (cyclone formation is not anticipated)

Tropical Wave 2 (mid-Atlantic)

Currently contains scattered showers and thunderstorms. 

Likely to bring moisture over T&T on Sunday/Monday.

Tropical Wave 3 (East Atlantic)

Disorganised showers and thunderstorms. 

Conditions appear conducive for development early next week while the system moves westward over the tropical Atlantic.

40 percent chance of cyclone formation within five days.

Invest Area 95L (near Bahamas)

Surface trough which is gradually becoming better organized.

Conditions are becoming favourable for development as the system moves northwest.

80 percent chance of Cyclone formation within five days.
