Hurricane Enrique Forecast Discussion Number 6
2021-06-26 17:24:15| National Hurricane Center (East Pacific)
Issued at 1000 AM CDT Sat Jun 26 2021 000 WTPZ45 KNHC 261523 CCA TCDEP5 Hurricane Enrique Discussion Number 6...Corrected NWS National Hurricane Center Miami FL EP052021 1000 AM CDT Sat Jun 26 2021 Corrected initial storm motion in second paragraph Enrique continues to exhibit a well organized structure on satellite imagery. First-light visible shows the formation of a ring of overshooting tops along Enrique's north and west sides, a sign that an eyewall is organizing. Indeed, a recent 1207 UTC SSMIS microwave pass showed this formative eyewall, though some dry air also appears to be wrapping around the hurricane along its eastern flank. Satellite intensity estimates this morning include subjective Dvorak estimates of T4.0/65 kt from TAFB, T4.5/75 kt from SAB, and an objective estimate of T4.3/72 kt from UW-CIMSS ADT. The initial intensity is increased to 75 kt for this advisory, favoring the higher intensity estimates based on the improvement in satellite structure since 1200 UTC. Satellite imagery suggests that the estimated motion is beginning to bend a bit rightward at 300/06 kt. As the mid-level ridge to the north of the storm weakens over the next day or so, Enrique should slow down and turn a bit more to the northwest. The large region of monsoonal southwesterly flow south and east of the hurricane may also be influencing this rightward bend in the track in the short term. The new forecast track has shifted again to the right, especially over the first 48 hours, following the track guidance consensus and close to the most recent ECMWF ensemble mean. The small size of the 64-kt wind radii forecast with Enrique should keep the highest winds offshore, but any additional eastward track adjustments could require hurricane watches for portions of the southwestern coast of Mexico later today. Conditions remains favorable for Enrique to intensify further in the short term, and the current rapid intensification cycle is expected to continue the next 12 to 24 h with the hurricane peaking at 95 kt. Thereafter, an increase in easterly shear could help import dry down-sloping flow off the higher Mexican terrain into Enrique's core. In addition, the depth of warm sea-surface temperatures along Enrique's track becomes increasingly shallow and any further slowdown in the forward motion would result in cool ocean upwelling. Thus, Enrique is expected to begin weakening after 24 h, and this steady weakening should continue through the end of the forecast period as sea-surface temperatures decrease along the forecast track. Key Messages: 1. The outer rainbands of Enrique are likely to produce heavy rains across a portion of southwestern Mexico during the next couple days, which would likely cause life-threatening flash flooding and mudslides. 2. Tropical-storm-force winds are expected across portions of southwestern Mexico today and this weekend, and a Tropical Storm Warning is in effect for a portion of that area. 3. Swells generated by Enrique are expected to affect the southwestern coast of Mexico during the next few days. These swells could cause life-threatening surf and rip currents.

Hurricane Enrique Forecast Discussion Number 5
2021-06-26 10:55:39| National Hurricane Center (East Pacific)
Issued at 400 AM CDT Sat Jun 26 2021 666 WTPZ45 KNHC 260855 TCDEP5 Hurricane Enrique Discussion Number 5 NWS National Hurricane Center Miami FL EP052021 400 AM CDT Sat Jun 26 2021 The cloud pattern of Enrique has continued to become better organized since the last advisory, with a well-defined central dense overcast and a small, but persistent, area of cloud tops colder than -80C that may be the top of an eyewall. Satellite intensity estimates include subjective Dvorak estimates of 55 kt from TAFB and SAB and an objective estimate of 65 kt from the CIMSS ADT. The initial intensity is increased to 65 kt based mainly on the latter estimate. Although the cyclone continues to intensify, cirrus cloud motions to the west of the center suggest some shear is occurring. The initial motion is 290/7. A mid-level ridge to the north of the storm is forecast to weaken over the next day or so which should cause Enrique to slow down and bend northwestward between 24-60 h. After that time, the ridge is expected to re-strengthen, causing the tropical cyclone to turn west-northwestward once again. The track guidance has shifted a little to the right since the last advisory during the first 72 h, and the GFS model continues to show a sharper northward turn that would bring the center closer to the coast of Mexico. The new forecast track is also shifted a little to the right during the first 72 h, but it lies west of the various consensus models. Any subsequent adjustment of the forecast track to the right/east could require a hurricane watch for portions of the southwestern coast of Mexico later today. Enrique is forecast to remain within an environment of low vertical wind shear and over warm sea surface temperatures during the next 24 to 36 hours. Therefore, continued steady to rapid strengthening is likely as indicated by the Rapid Intensification Indices of the SHIPS model. The new intensity forecast calls for a peak intensity of 95 kt at 36 h, which is near the high end of the intensity guidance. After 36 h, increasing shear and decreasing sea surface temperatures along the forecast track should cause a steady weakening. Key Messages: 1. The outer rainbands of Enrique are likely to produce heavy rains across a portion of southwestern Mexico during the next couple days, which would likely cause life-threatening flash flooding and mudslides. 2. Tropical-storm-force winds are expected across portions of southwestern Mexico today and this weekend, and a Tropical Storm Warning is in effect for a portion of that area. 3. Swells generated by Enrique are expected to affect the southwestern coast of Mexico during the next few days. These swells could cause life-threatening surf and rip currents.
