A weekly discussion of the tropics from the Eyewitness News Forecast Team
 

Time to talk some tropics: the main focus early this week is the tropical wave off the coast of Africa. This system is a broad low pressure area that looks rather big and bad on satellite… but it’s not going to be a major threat.

Here’s why: even though the system could strengthen a bit through midweek, it will have a tough time staying together when it charges into the central Atlantic Ocean. That’s where it will meet stronger winds and much drier air. Those factors will sap much of its strength.

Another inhibitor will be cooler waters in the central Atlantic, where water temps are close to 80° or even upper 70s. Without warm water for fuel, this system should weaken dramatically by the end of the week.

Other than the wave near Africa, there’s not much to talk about right now. High pressure and dry air are dominating the Gulf and most of the Caribbean Sea, so mostly fair weather is on tap near us.

A weak tropical wave over the Dominican Republic will drift toward Cuba by midweek, but high mountains and dry air will tear it up.

Remember to keep watching your tropical video updates from the Eyewitness Forecast Team. Carl, Laura, Derek and Alexandra post new updates several times a day.
