SAN JUAN — A tropical wave over the central Tropical Atlantic continues to produce disorganized showers and thunderstorms that are a little more concentrated near its axis.
Environmental conditions appear conducive for gradual development of this system, and a tropical
depression could form by early next week while it moves westward at 10 to 15 mph, approaching the Lesser Antilles.
The system is then forecast to continue moving westward to west-northwestward across portions of the eastern and central Caribbean Sea by the middle part of next week.
An excessive heat warning is in effect for St. Croix from 10:00 a.m. to 5:00 p.m. today.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 7 days…medium…50 percent.
Meteorologist Brian Shields shows the likely path of Disturbance 1 next week.
MARINE FORECAST FOR THE USVI AND PUERTO RICO
Expect lighter winds through tomorrow. Moderate to locally fresh easterly winds will dominate over the next few days. Isolated to scattered showers are expected across the local waters, with isolated thunderstorms affecting the coastal waters of western Puerto Rico each afternoon.
Consequently, locally choppy conditions for small craft are likely. The passage of the next tropical wave could further deteriorate marine conditions by next week.
EASTERN TROPICAL ATLANTIC
Another tropical wave just west of the coast of Africa is currently associated with an area of disorganized showers and thunderstorms.
Some slow development of this system is possible through the middle portion of next week as it moves slowly to the west-northwest or northwest over the Eastern Tropical Atlantic.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 7 days…low…20 percent.
