Tropical Storm Dalila Forecast Discussion Number 9

1 month 1 week ago
Issued at 300 PM CST Sat Jun 14 2025 584 WTPZ44 KNHC 142033 TCDEP4 Tropical Storm Dalila Discussion Number 9 NWS National Hurricane Center Miami FL EP042025 300 PM CST Sat Jun 14 2025 Deep convection continues to burst over the center of Dalila, with cold cloud tops near -80 C and a well-defined convective band shown in satellite imagery. A recent scatterometer pass showed peak winds near 55 kt, which prompted an increase in the estimated intensity to 55 kt during the intermediate advisory. Since then, the convective structure has remained steady, and with both objective and subjective satellite intensity estimates continuing to support this intensity, thus, the initial intensity is held at 55 kt for this advisory. The initial motion is estimated at 300/9 kt. The storm is expected to continue moving toward the west-northwest into tonight, then begin turning toward the west by Sunday as the mid- to upper-level ridge continues to strengthen to the north. The forecast guidance remains in good agreement with this scenario, and the new forecast track is close to the various consensus models and is similar to the previous NHC forecast. Dalila has likely reached its peak intensity and the storm may maintain its current strength for a few more hours. By Sunday, the storm will begin moving over cooler waters and into a drier, more stable environment, which will initiate a weakening trend. The system is forecast to become a remnant low in 48 hours, then dissipate into an open trough in 72 hours. The NHC intensity forecast closely follows a blend of the statistical-dynamical guidance and is very similar to the previous forecast. KEY MESSAGES: 1. The outer bands of Tropical Storm Dalila will bring locally heavy rainfall to the Mexican states of Michoacán and Guerrero through Sunday morning. Scattered areas of flooding and mudslides are expected, especially in areas of steep terrain near the coast. 2. Dalila is expected to produce tropical-storm-force winds across portions of the warning area today.

Tropical Storm Dalila Forecast Discussion Number 8

1 month 1 week ago
Issued at 900 AM CST Sat Jun 14 2025 251 WTPZ44 KNHC 141434 TCDEP4 Tropical Storm Dalila Discussion Number 8 NWS National Hurricane Center Miami FL EP042025 900 AM CST Sat Jun 14 2025 Dalila continues to show signs of strengthening, with deep convection bursting over the low-level center, and curved banding features near the coast of southwestern Mexico. There is a fairly large range of satellite intensity estimates this morning from 45 to 65 kt. Given the improving satellite presentation, the initial intensity is raised to 50 kt for this advisory. A scatterometer pass is scheduled over the system around 16Z, which may give a better estimate of surface winds. The storm is currently moving northwestward at an estimated 305/10 kt. A mid-level ridge is building westward over northern Mexico, which should cause Dalila to gradually turn west-northwestward later today. As the system begins to weaken into a shallower vortex on Sunday, Dalila will turn more westward within the low-level wind flow. The latest NHC forecast is near the previous one, and lies near the latest simple and corrected consensus aids. Dalila may be nearing peak intensity, with only about 6 to 12 h left within a favorable environment. Thus, the NHC forecast shows slight strengthening today, with a peak intensity of 55 kt. Along the forecast track, Dalila will move over much cooler SSTs tonight and begin to enter a drier, more stable airmass. This will lead to steady weakening, and eventually the system will struggle to produce convection. The NHC intensity forecast is near the previous one, however now shows the system becoming a remnant low in 48 h, although this could occur sooner. By day 4, models depict the remnant low dissipating into an open trough. KEY MESSAGES: 1. The outer bands of Tropical Storm Dalila will bring locally heavy rainfall to the Mexican states of Michoacán and Guerrero through Sunday morning. Scattered areas of flooding and mudslides are expected, especially in areas of steep terrain near the coast. 2. Dalila is expected to produce tropical-storm-force winds across portions of the warning area today.
