Potential Tropical Cyclone Four was a weak tropical disturbance that impacted northeastern Mexico and southern Texas in August 2022. As of July, it is one of only three systems to be designated a Potential Tropical Cyclone and not form, along with Potential Tropical Cyclone Ten of the 2017 and Potential Tropical Cyclone Seventeen-E of the 2019. The disturbance was first noted as a tropical wave in the central Caribbean Sea on August 15. The system emerged in the southern Gulf of Mexico early on August 19, producing disorganized showers. It was this point when the National Hurricane Center (NHC) started to issue advisories on the system as Potential Tropical Cyclone Four at 21:00 UTC. as the disturbance moved across the western Gulf, Four failed to develop a defined center and at the same time, deep convection significantly decreased. The disturbance moved inland over northeastern Mexico on 00:00 UTC on August 21 and soon after, dissipated.

Metrological history
The origins of Potential Tropical Cyclone Four can be traced back to a tropical wave in the central Caribbean Sea on August 15. The wave emerged over Bay of Campeche early on August 19, producing disorganized showers. The NHC decide that the threat that the system posed to northeastern Mexico and South Texas was big enough to initiate advisories on Potential Tropical Cyclone Four at 21:00 UTC that same day. As Four moved northwestwards in the Gulf of Mexico on August 20, hurricane hunter aircraft investigated the system on and found that the system was still a surface trough. At around 00:00 UTC on August 21, it moved inland about 60 mi southwest of the mouth of the Rio Grande. Since it was clear at this point that the system would no longer develop into a tropical cyclone, the last warning was issued for Four at 03:00 UTC on August 21.

Preparations and impact
When the disturbance was designated, the Government of Mexico and the National Weather Service office in Brownsville, Texas issued a tropical storm warning from Boca de Catan, Mexico to Port Mansfield, Texas. The tropical storm warning was lifted after the disturbance moved inland on August 21.

Four brought heavy rains and minor flooding to the Texas coast and northeastern Mexico. However, there was no significant damage related to the storm.
