The National Hurricane Center in its 5:00 a.m. advisory said three tropical waves with varying chances of development were churning in the Atlantic Ocean, all of which, according to the current trajectory, could affect the Caribbean in the coming days.
There’s one located about 600 miles southwest of the Cabo Verde Islands, with N.H.C. projecting that gradual development of this system is possible during the next several days and a tropical depression could form early next week while it moves westward across the tropical Atlantic. This system has a 60 percent chance of development within the next five days, and a 20 percent chance within 48 hours.
Another area of disturbed weather located about 1000 miles west-southwest of the Cabo Verde Islands may merge with the tropical wave approaching from the east over the weekend, N.H.C. said. However, some development of this system is possible through early next week as long as it remains a distinct system. The disturbance is forecast to move slowly westward.
There’s also a fast-moving tropical wave located about 1000 miles east of the Lesser Antilles. This system is producing limited shower activity, and development, if any, should be slow to occur during the next couple of days while the wave moves quickly westward across the tropical Atlantic. Conditions could be a little more conducive for development in a few days when the wave moves over the eastern Caribbean Sea.
Tropical Storm Humberto
According to the National Hurricane Center, the center of Tropical Storm Humberto was located near latitude 26.3 North, longitude 76.0 West. The storm is moving toward the northwest near 7 mph (11 km/h), and this motion is expected to continue through tonight. A turn toward the north-northwest is expected by Sunday, with a slower northward to northeastward motion forecast to occur by Monday.
On the forecast track, T.S. Humberto is anticipated to move near or over the northwestern Bahamas today, and offshore of the east coast of Florida this weekend and early next week. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual strengthening is forecast, and Humberto is expected to become a hurricane by Sunday night. Tropical-storm-force winds extend outward up to 90 miles (150 km) from the center. The estimated minimum central pressure is 1007 mb (29.74 inches).
