The National Hurricane Center is monitoring three tropical systems, two of which have yet to develop into tropical depressions but could sometime this week.

In the northern Gulf of Mexico, an area of low pressure is spinning off the Florida panhandle, south of Panama City.

It's possible a tropical depression forms before the system moves ashore Monday. But the higher chance for development will unfold after it moves over into the Atlantic Ocean later in the week.

"This system is expected to evolve into a larger low pressure system and move northeastward, possibly emerging offshore of the Carolinas later this week where environmental conditions are expected to be more conducive for development," the NHC said in a Sunday evening tropical update.

The system has 40% chance of tropical development in the next five days, according to the NHC's forecast.

Meanwhile, a tropical wave about 700 miles east of the Winward Islands in the Caribbean Sea also has forecasters' attention too, but the window of time for it to develop into a tropical depression is narrow.

"Some slight development of this system is possible on Monday before environmental conditions become hostile for development on Tuesday," the NHC said.

Tropical Depression 5, centered northeast of Bermuda, is forecast to possibly become Tropical StormEdouard on Monday.

If that occurs, a record would be set for the earliest a fifth-named storm has formed in a hurricane season.

Colorado State University meteorologist Philip Kloztbach said that the current record for the earliest fifth-named storm formation was Emily on July 12, 2005.
