Time has essentially run out for notable tropical development of a unorganized low (Invest 93L) in the Gulf. The National Hurricane Center still gives the system a low chance to become a tropical depression, but low even seems too high at this point.
Regardless, the forecast has not changed in regards to heavy rain and flooding, which still looks likely between Texas and Alabama through Friday.
Regardless of whether it develops into a tropical cyclone, the system is capable of producing heavy rainfall. Flood Watches are in effect for portions of Louisiana and Mississippi.
Many forecast models have the potential of 2-6"+ of rainfall over the next several days for the Gulf Coast. Isolated totals of 6-12" are not out of the question, which could lead to a localized high end flooding risk.
The risk for flash flooding is expected to be highest on Thursday, with a gradual drop in flood potential though Saturday as remnant moisture is slow to leave the reigon.
