Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionThe origins of Vicente can be traced back to a tropical wave and a low-level vortex associated with the Eastern Pacific monsoon trough. The wave departed from the west coast of Africa on October 6 and reached the Lesser Antilles by October 14. A day later, convection associated with the wave diminished, with it being completely devoid of convection until October 16. The wave then crossed over Central America and entered the Eastern Pacific Ocean. Convection then redeveloped along the monsoon trough located south of Panama on October 17.[1] Early on October 19, the NHC began monitoring the trough for tropical development as it slowly travelled westward.[2] The system quickly organized over the next six hours, consolidating into Tropical Depression Twenty-Three-E by 06:00 UTC while about 90 mi (150 km) west-southwest of Puerto San Jose, Guatemala.[1] At that time, the depression was located in a favorable environment with sea surface temperatures of 28–29 °C (82–84 °F) and low vertical wind shear.[3] After having developed well-defined convective banding, the system was upgraded to a tropical storm. At that time, Vicente was traveling towards northwest under the influence of a mid-level ridge, which was situated over northern Mexico and the Gulf of Mexico.[4]
Soon after, Vicente began to be affected by 10–15 knots (12–17 mph; 19–28 km/h) of northwesterly wind shear as it paralleled the Guatemalan coast. Due to Vicente's small size, the wind shear caused it to quickly become disorganized. The storm's low-level center was almost entirely exposed as it accelerated away from its deteriorating central dense overcast.[5]
