The National Hurricane Center is tracking three low-pressure systems along the Inter Tropical Convergence Zone in the northeast Atlantic. Current models show that conditions are conducive for them to continually organize and strengthen over the next several days. Two of them have 40% chance of cyclone formation within the next 48 hours. The third is expected to develop through the next 5 days. All of them are moving toward the Caribbean Sea. The first low-pressure

system is currently located about 1 287 km (800 miles) east of the Lesser Antilles. It became a little better defined since yesterday, but most of the associated shower and thunderstorm activity is displaced to the west of the center of circulation, according to the NHC.  Upper-level winds are forecast to become more conducive for development during the next day or so while the low moves westward at 24 to 38 km/h (15 to 20 mph) across the tropical Atlantic Ocean, crossing into the Caribbean Sea on Friday.  READ MORE
