A broad area of low pressure moving towards Louisiana in the northern Gulf is not showing signs of further organization, but its heavy rain threat remains.
"The current forecast calls for 1-3 inches for areas north of the I-10/12 corridor and 3-5 inches of rainfall along and south of the I-10/12 corridor with the potential for up to 10 inches in some localized areas (especially along the coast) during the Wednesday through Saturday time frame," the National Weather Service office in Slidell said. "However, it is still possible the heaviest rainfall stays just offshore. Ponding of water in low lying and poor drainage areas is likely, with potential for more significant impacts (such as water approaching low-lying structures) if the higher end rainfall totals are realized."
"Surface and radar observations indicate that a broad area of low pressure is moving westward across the Florida Panhandle between Tallahassee and Panama City. The associated shower and thunderstorm activity is disorganized and located mainly south and southwest of the center," said the National Hurricane Center Wednesday morning. "This system is forecast to continue moving westward, and could emerge or redevelop over the far northeastern to north-central portion of the Gulf later today or tonight, reaching the coast of Louisiana by Thursday. If this system moves far enough offshore, environmental conditions over the Gulf appear generally favorable for additional development, and a tropical depression could still form over the next couple of days before the system moves fully inland by the end of the week."
