A broad area of low pressure is located over the central Gulf of Mexico. Although the shower activity is still disorganized, upper-level winds are forecast to become more conducive for development, and it is likely that a tropical depression will form Thursday or Thursday night, before the system reaches the western Gulf coast. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the disturbance tomorrow, if necessary. Regardless of development, heavy rainfall and gusty winds are expected across portions of northeastern Mexico, Texas, and Louisiana late this week. Interests there should monitor the progress of this system, and refer to products from their local weather office. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...70 percent.
