What else is out there and where is it?
Invest 91L: A broad area of low pressure located near the southern Windward Islands continues to produce a large area of disorganized showers and thunderstorms.
How likely is it to strengthen?
Invest 91L: Radar imagery from Barbados and surface observations indicate the system has not become any better organized since yesterday.
However, upper-level winds are forecast to become more conducive for development, and a tropical depression is likely to form over the next several days if the system remains over water while moving generally westward at about 15 mph over the southeastern and southern Caribbean Sea.
An Air Force reconnaissance mission is currently en route to investigate the system this morning.

It's too early at this time to determine if there will be any impact to the U.S. from the tropical wave.
