WEST PALM BEACH, Fla. — Forecasters are keeping their eyes on two new systems that formed in the Atlantic over the weekend. Both systems have moderate to high chances of becoming tropical cyclones.

Invest 97L is working its way into the eastern Caribbean Sea. In the short term, it is not expected to develop.

But in the longer term, the wave could become a tropical depression as it starts to turn towards the north.

It could interact with the Yucatan Peninsula, which will slow its progression, and it's expected to battle wind shear at that time. The system is little threat to our area.

As of 2 a.m. Wednesday, the system has a 80 percent chance of development.

Second Tropical Wave

Invest 98L could threaten us here locally. There's still a lot of uncertainty with this system, which is sitting several hundred miles southwest of the Cabo Verde islands. The National Hurricane Center is giving this system a high chance of formation into the next two to five days.

It should become a tropical depression in one to two days. Both the GFS and European computer models keep it just south of us, but that could easily change. The next two name are Laura and Marco.

As of 2 a.m. Wednesday, the system has a 90 percent chance of development.

Third tropical wave
The third tropical wave hasn't come off Africa yet, but once it does in a few days it has a 20% chance to develop. It's too early to tell what it's going to do.
