000 WTPZ43 KNHC 100234 TCDEP3 Tropical Storm Cristina Discussion Number 8 NWS National Hurricane Center Miami FL EP032026 900 PM CST Tue Jun 09 2026 Unlike 24 hours ago, Cristina's low-level center is difficult to find this evening. While convection has continued to pulse near and to the south of the estimated center, it only has modest organization. An afternoon OSCAT pass suggested the center was slightly farther south than earlier today, and radar images out of Nicaragua do show some broad mid-level turning in the same vicinity. Satellite intensity estimates have not changed much from earlier today, and the initial intensity remains 35 kt for this advisory. Piecing together the data, it appears Cristina is starting to crawl along a little south of due west, with an estimated motion of 260/2 kt. The track guidance is in a bit better agreement, showing a very slow westward motion in the short-term. Then, as a mid-level ridge builds in from the east over the Caribbean Sea, the track guidance responds by showing a sharper turn to the northwest in 24-36 h, bringing Cristina inland near El Salvador during this period. The storm should then quickly dissipate over the higher terrain of Central America. Given the farther southward initial position, the latest NHC track forecast was nudged a bit southward early on, but converges fairly close to the previous forecast track after 24 h. Vertical wind shear over Cristina has decreased over the past day, now under 20 kt out of the northeast. The system remains over very warm sea-surface temperatures with ample deep-layer moisture. However, it is unclear how intact Cristina's circulation is after brushing up close to the high terrain of Nicaragua last night. Moreover, most of the dynamical models show very little intensification in the short term. For these reasons, the NHC intensity forecast will continue to only show modest intensification in 24 h before Cristina's circulation nears El Salvador and starts to interact with the mountainous terrain of Central America once again. After the storm moves inland, rapid weakening is expected, with dissipation anticipated by 60 h. Key Messages: 1. Heavy rainfall associated with Tropical Storm Cristina will impact coastal portions of Central America through Thursday. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain. 2. Tropical storm conditions, especially in gusts, are expected to impact portions of the coasts of Nicaragua, El Salvador, and Honduras tonight into Wednesday.
