Please see the below weather update from the National Weather Service (NWS) New Orleans / Baton Rouge.
The Hurricane Center is continuing to monitor a trough of low pressure located over northeastern Mexico which is producing a large area of disorganized showers and thunderstorms.
Development is not expected during the next day or so while the trough remains inland. However, the system could re-emerge over the northwestern Gulf of America late Tuesday or Wednesday, and environmental conditions there are marginally conducive for the formation of a short-lived tropical storm on Wednesday into Thursday.
Regardless of tropical cyclone formation, interests across southern and eastern Texas and portions of Louisiana and Mississippi should prepare for periods of intense rainfall over the next several days.
* Formation chance through 48 hours...medium...40 percent.
