And now Invest 91L is up to a 70% chance of tropical development within the next 5 days:
A broad and elongated area of low pressure is located over the central tropical Atlantic Ocean. Although the associated shower and thunderstorm activity has increased somewhat since yesterday, it currently lacks organization. Environmental conditions are expected to be generally conducive for gradual development, and a tropical depression is likely to form later this week while moving toward the west and then west-northwest at around 10 mph, toward the waters east of the Leeward Islands. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...high...70 percent.
