Forecasters said a low pressure system will likely develop into a tropical depression late in the week in the Gulf of Mexico. 

On Monday evening, an area of disorganized storms was over the Bay of Campeche and is expected to gradually strengthen while it meanders near the coast of Mexico.

By midweek, the system should begin to move north.

The NHC has not said if and where the system will hit the Gulf Coast, but Louisiana could get up to 4 to 10 inches of rain on Friday, with some areas seeing more than 10 inches, regardless of development.

A system off the coast of North Carolina strengthened into a tropical depression earlier Monday and will likely develop into the second named tropical storm of the year by tonight, forecasters said. It will be named Bill. 

The tropical depression is forecast to move away from the East Coast and therefore doesn’t pose an immediate threat to land.

The storm’s center was about 200 miles east of Cape Hatteras, North Carolina, as of 7 p.m., according to the National Hurricane Center. It has winds of 35 mph and is moving northeast at 18 mph.

Last year’s hurricane season broke several records, including having the most named storms ever on record.

Forecasters said the system is only expected to strengthen slightly after becoming a tropical storm. It will dissipate by Wednesday south of Nova Scotia.

A strong tropical wave off of Africa’s west coast was also being monitored Monday evening. It has a 20% (low) chance of developing into a depression within the next five days. 

The Atlantic hurricane season runs from June 1 through Nov. 30.
