Localized flooding in Houston is possible Friday as a tropical disturbance in the western Gulf of Mexico approaches the Texas coast.

The odds of a short-lived tropical depression or storm forming in the southwestern Gulf are lessening, but pockets of heavy rain could still trigger flash flooding.

The system will likely bring heavy rainfall over southern Texas over the next few days, according to the National Hurricane Center (NHC). There is a low chance of the system developing into a tropical depression, with the NHC reporting a 20 percent chance of formation through the next 48 hours or seven days.
