639 WTPZ43 KNHC 191436 TCDEP3 Tropical Depression Celia Discussion Number 12 NWS National Hurricane Center Miami FL EP032022 1000 AM CDT Sun Jun 19 2022 Similar to yesterday, a widespread area of deep convection has formed along and south of the Gulf of Tehuantepec, likely in association with an ongoing gap wind event. There has also been a few more clusters of deep convection developing just west of Celia's estimated low-level center. Despite this activity, none of it is especially well-organized and remains primarily down-shear of Celia's vortex. However, it is enough coverage for now to keep Celia as a classifiable tropical cyclone. The initial intensity remains 25 kt this advisory, favoring the lower SAB Dvorak classification given the lackluster winds found with overnight scatterometer and a ship report near the center. Celia's motion continues off to the west, estimated at 265/7 kt. The track guidance is in fairly good agreement that a west-southwest motion will continue for the next 36 h as Celia is steered by a deep-level ridge to the north supplemented by low-level northerly flow from a gap wind event in the Gulf of Tehuantepec. Afterwards, a turn to the west and west-northwest is anticipated as Celia becomes positioned on the southwest side of the deep-layer ridging. The NHC track forecast was nudged slightly south again from the prior one following a southward adjustment in the latest consensus aids (HCCA, TVCE). Moderate to strong east-northeasterly vertical wind shear over the next 24-36 hours still appears likely to keep Celia in check, and the system is forecast to remain a depression during that time. Afterwards, both the GFS- and ECMWF-based SHIPS guidance indicates this shear should gradual subside as the system moves over 28-29 C sea-surface temperatures. The majority of the intensity guidance responds to this environment by showing intensification, and the latest NHC intensity forecast was nudged upward just a bit after 36 hours. This forecast is a blend between the lower HCCA and higher IVCN consensus aids, and is quite close to the most recent COAMPS-TC (CTCI) forecast in 120 hours.
