AUSTIN (KXAN) — A disturbance in the northern Gulf of Mexico still lurks off the coast of Louisiana Tuesday, with eyes set on Texas impacts Thursday and Friday.

There still remains uncertainty as to where this tropical low will come ashore, but there is increasing confidence that this disturbance will stay sub-tropical storm strength as it runs out of ocean real estate before getting pushed over land. The National Hurricane Center has a 30% probability of further organization within two days.

ANALYSIS: What are the models saying?

Two of the various models we use to evaluate possible impacts show two different outcomes.

The European (ECMWF) model shows a more easterly track with the heaviest rain favoring east Texas, leaving Central Texas with minimal rainfall accumulation.

The American (GFS) model shows a more southerly, disorganized track that would leave our southern counties favored for ~1″ of rain, and lesser amount elsewhere.
