There are two main weather features we'll need to watch out for as the week rounds-out. The first of these is a tropical wave that extends across Cuba and the Bahamas. The wave axis is significant in length... from the Caribbean northward into the Atlantic Ocean. Then, the associated moisture extends well to the east (keeping weather conditions unsettled across many of the island nations in the Caribbean). We'll be paying attention to the progress of the wave and a big batch of tropical moisture. Our local forecast for the weekend depends on the proximity of the tropical wave and the associated airmass. In addition to the wave, we're also keeping tabs on distant Tropical Depression Five. It has a good chance of strengthening into Tropical Storm Ernesto as the week continues. Regardless of that potential, we'll have many days to monitor it. The National Hurricane Center predicts a general track to the west or west-northwest. The tropical system will probably impact the Windward Islands on Friday (where there are tropical storm watches in effect). The longer-range forecast track takes the system into the eastern Caribbean Sea during the weekend. The 5-day track, then, continues it... basically the length of the Caribbean with a gradual increase in strength. There is also a chance it could become a low-end hurricane in the vicinity of the northwest Caribbean (in several days).
Recently, we've simply had some typical afternoon thunderstorms. Looking ahead, there's a good chance we'll see more numerous rounds of rain with thunder as the week ends. Be prepared for tropical-type downpours with gusty winds. You may need to adjust your outdoor plans. Stay tuned and watch for changing sky conditions.
