A broad trough of low pressure is producing disorganized showers and thunderstorms over the east-central tropical Atlantic more than 1000 miles west-northwest of the Cabo Verde Islands. Little development is expected during the next day or two due to marginally conducive ocean temperatures and strong upper-level winds. Afterwards, environmental conditions are expected to become more favorable for gradual development, and a tropical depression could form by the end of the week while the system moves northwestward to northward at 10 to 15 mph over the central Atlantic. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...medium...50 percent. A tropical wave over the eastern Caribbean Sea is expected to form a broad area of low pressure over the southwestern Caribbean Sea later this week.
