(CNN) -- A low-pressure weather system over the western Gulf of Mexico has an increasing chance of becoming a tropical depression or a more severe storm over the next 48 hours, the National Hurricane Center said in Wednesday's 2 p.m. ET advisory.

The disturbance now has a 50 percent chance of becoming a tropical cyclone, with winds rotating around a low-pressure core, before it moves inland over northeastern Mexico or southern Texas on Thursday, said the Hurricane Center. Wednesday morning, the probability was 40 percent.

Center forecasters said showers and thunderstorms have become a little more concentrated about 300 miles east-southeast of the Texas-Mexico border. The disturbance is moving west-northwest at 10 to 15 mph.

If the system turns into a tropical storm or hurricane, it would be named Bonnie. Regardless of further development, the hurricane center predicts locally heavy rains and gusty winds in portions of eastern Texas and northeastern Mexico over the next few days.
