Proving that conditions in the tropics can change literally overnight, Tropical Storm Kirk, once a promising storm racing across the Atlantic, has dissipated as of Monday morning.

Kirk had degenerated into a tropical depression late Sunday night, degrading further into a trough of low pressure well east of the Lesser Antilles. The storm had been taking a punishing pace across the Atlantic, but was unable to maintain the central organization and closed circulation that characterizes a tropical cyclone. The National Hurricane Center discontinued public advisories during its 11 a.m. update.

Subtropical Storm Leslie is still meandering through the Atlantic, though advisories have the storm moving east, toward Africa, rather than west toward the U.S. Though the storm is of considerable size — with 40 mph winds extending over 200 miles from its center — its moving at a glacial 5 mph. The NHC expects the storm to turn east northeastward by Wednesday and possibly pick up speed. The system will likely strengthen.

Another system, a non-tropical cold front, has about a 50 percent chance of developing over the next five days. This system is directly in the path of Leslie and the two are expected to interact, and possibly merge, by midweek.

The trough of low pressure known as Disturbance 1 halfway between Bermuda and the Bahamas has about 40 percent chance of developing over the next five days according to the NHC, but will encounter upper level winds by Wednesday that could hamper its chances. If it develops, the storm could hit the already storm-weary North Carolina coast.

There are still two months left of hurricane season.
