The National Hurricane Center was monitoring two tropical waves Friday evening (July 29). Here is the 7 p.m. tropical weather outlook:
A tropical wave located about 1,000 miles east of the Lesser Antilles is moving westward at 20-25 mph. Associated shower activity is poorly organized, and given the fast motion of the system any development should be slow to occur.
Regardless of development, this system will likely bring showers and gusty winds to portions of the Leeward Islands, Virgin Islands, Puerto Rico, and the eastern Caribbean Sea during the weekend. By the middle of next week, the wave is expected to be in the western Caribbean Sea, where conditions could become more conducive for development.
Tropical formation chances are 10 percent over the next 48 hours and 30 percent over the next five days.
Shower and thunderstorm activity associated with a tropical wave and a low pressure system centered a couple of hundred miles south of Cabo Verde continues to show signs of organization.
Although this system does not have a well-defined circulation at this time, some development is still possible during the next day or two before the disturbance encounters a less favorable environment over the central tropical Atlantic early next week.
Formations chances are 40 percent through 48 hours and 50 percent over the next five days.
