The National Hurricane Center was tracking three disturbances Wednesday in the Caribbean and the Atlantic Ocean. Two of the systems are expected to develop into tropical depressions.
The system heading for the Caribbean is worth watching, the National Weather Service in Slidell said, but it's too early to tell if it could reach the Gulf Coast.

Here's what to know about the tropics as of 7 a.m. Wednesday.
Tropical depression likely to form in Caribbean

A disturbance in the Caribbean Sea has an 80% chance (high) of developing into a tropical depression within five days, the National Hurricane Center said.
The disturbance -- a tropical wave -- is moving west at 15 to 20 mph and is expected to move across the central Caribbean Sea on Wednesday. Some gradual development is possible over the next day or so while it is moving, forecasters said.
After that, the disturbance is supposed to slow down and turn northwest. A tropical depression is likely to form late this week or this weekend when it reaches the northwestern Caribbean Sea, forecasters said. It's too early to tell what the system could do after that.
Tropical depression likely to form in the Atlantic

A tropical depression is likely to form in the next day or two from a system moving across the Atlantic, forecasters said.
As of Wednesday morning, an elongated area of low pressure was about 1,000 miles east of the Windward Islands. It continues to produce a concentrated area of showers and thunderstorms, mainly on the west side, forecasters said.
The disturbance is moving northwest at 15 to 20 mph.
It has a 90% chance (high) of developing into at least a tropical depression within 48 hours, forecasters said.
Tropical wave over Guinea and Sierra-Leone
Some development is possible with a "vigorous" tropical wave that's over Guinea and Sierra-Leone, forecasters said Wednesday morning, Aug. 19, 2020. (Image via National Hurricane Center)
Some development is possible with a "vigorous" tropical wave that's over Guinea and Sierra-Leone, forecasters said.
The disturbance is expected to enter the extreme eastern Atlantic on Friday, and environmental conditions will be marginally conducive for some development.
By early next week, forecasters said, conditions are expected to become less favorable for development. It's expected to move northwest at 15 to 20 mph toward the central tropical Atlantic.
It has a 20% chance (low) of developing into a tropical depression within five days.
What else to know?
The next two names on this year's list are Laura and Marco. Systems are named once they strengthen to a tropical storm.
No other storms are expected to form in the next 48 hours in the Gulf of Mexico, the Caribbean or the Atlantic.
The peak of hurricane season, which is Sept. 10, is approaching. The Atlantic hurricane season ends Nov. 30.
