A tropical threat on the Gulf Coast has a 40% chance for development into a tropical depression by Friday, according to the National Hurricane Center Wednesday morning.
The system, which could currently be considered a tropical rainstorm or tropical disturbance, is likely to bring heavy rain to the central Gulf Coast for days — especially to Louisiana.
The disturbance is expected to move along the coast, but the closer it stays to shore, the less chance it will have to grow into a tropical depression or storm, though a change to a more southerly track would give it a chance to gain steam.
This tropical disturbance is expected to produce long duration heavy rainfall and, if it develops into a tropical storm, it would be named Dexter.
