Tropical Update
Satellite imagery shows a better-defined center of circulation is forming in association with a low pressure system located about 900 miles WSW of the Cabo Verde Islands. The associated shower and thunderstorm activity has become more organized since yesterday. Environmental conditions are expected to become more conducive for additional development, and a tropical depression could form as early as today if these development trends continue. The disturbance is forecast to move WNW at around 15 mph across the tropical Atlantic during the next few days. Conditions are expected to become less conducive for development by the end of the week.
* Formation chance through 48 hours: High (90%)
* Formation chance through 5 days: High (90%)
