ORLANDO, Fla. - Meteorologists on Monday observed a developing system at the foot of South Florida, according to the National Hurricane Center's 2 p.m. EDT update.

A trough of low pressure producing showers and thunderstorms exists just south of the Florida Straits and is forecast to pass over South Florida on Tuesday and move toward the Atlantic, the NHC said.

"The disturbance is forecast to merge with a frontal boundary and developing low off the east coast of the United States by Wednesday," the NHC said. "No further development is anticipated after that time."

The system has a 10% chance of developing into a tropical depression in the next two to five days. It is expected to bring heavy showers over the South Florida community over the next 24 hours.

Meteorologists are tracking two other nontropical weather systems with increased chances of becoming tropical or subtropical depressions later this week.

The first is a nontropical low pressure system in the mid-Atlantic that is expected to strengthen along a frontal barrier between Bermuda and the Azores Monday night, the NHC said.

Meteorologists predict a 50% chance of forming into a tropical depression or subtropical depression within the next two to five days. The system is forecast to gradually develop while slowly drifting westward.

However, it is expected to move toward upper-level atmospheric winds, which are unfavorable for development, by Wednesday night.

The second system being tracked is a set of showers and thunderstorms located over the north Atlantic between Bermuda and the east coast of the United States; it is expected to move northwest as it develops.

There is a 30% chance of tropical development in the next five days.
