Saturday marks the official start of the hurricane season and right on cue, a disturbance in the Northwest Caribbean is shaping up to be a contender for the B-named storm of 2019.
A broad area of low pressure accompanied by cloudiness and showers is centered over the Yucatan Peninsula and is forecast to move westward over the Bay of Campeche, the National Hurricane Center said in a 2:20 p.m. special weather statement.
Some gradual development of the system could take place early next week if it remains over water long enough.
The center said the disturbance would produce heavy rainfall over portions of southern Mexico during the next few days.
It poses a 20 percent chance of developing over the next 48 hours and a 30 percent chance over the next five days.
If the system acquires a name it would be called Barry.
The center will begin issuing is Tropical Weather Outlook at 2 a.m. Saturday.
