Potential Tropical Cyclone Four was a weak tropical disturbance that impacted northeastern Mexico and southern Texas in August 2022. As of August 2024, 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.[1][2] The disturbance was first noted as a tropical wave in the central Caribbean Sea on August 15.[3] The system emerged in the southern Gulf of Mexico early on August 19, producing disorganized showers.[4] 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.[5]

Unknown
The origins of Potential Tropical Cyclone Four can be traced back to a tropical wave in the central Caribbean Sea on August 15.[6] The wave emerged over Bay of Campeche early on August 19, producing disorganized showers.[7] 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.[5] 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.[8] At around 00:00 UTC on August 21, it moved inland about 60 mi (95 km) southwest of the mouth of the Rio Grande.[9] 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.[5]
Preparations and impact
editWhen 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.[5]
Four brought heavy rains and minor flooding to the Texas coast and northeastern Mexico.[10] However, there was no significant damage related to the storm.[5]
