Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Sun Jun 15 2025

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Dalila, located in the eastern Pacific basin a couple of
hundred miles west of the coast of southwestern Mexico.

Offshore of Central America and Southeastern Mexico (EP94):
A broad area of low pressure continues to produce disorganized
showers and thunderstorms offshore Central America. Environmental
conditions are expected to be conducive for gradual development of
this system, and a tropical depression is likely to form by the
middle of this week while moving westward to west-northwestward just
offshore of the coasts of El Salvador, Guatemala, and southeastern
Mexico.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...70 percent.

Cloud tops have been warming, and what convection remains is displaced to the southwest. First-light visible imagery showed that the system has decoupled with the low-level center exposed due to moderate northeasterly wind shear. Given the current satellite presentation, subjective and objective intensity estimates have started to drop-off, and the initial intensity is lowered to 45 kt for this advisory. Dalila is moving towards the west-northwest, at an estimated 295/8 kt. As Dalila continues to weaken and becomes a shallower vortex, a turn towards the west is expected within the low-level wind flow. The current NHC track forecast is similar to the previous, near the consensus aids. The storm will continue to weaken today within a cooler SSTs and a drier, more stable environment. Dalila is already struggling to produce convection and should become a post-tropical cyclone later tonight. The latest intensity forecast shows steady weakening and the system dissipating in a couple of days.
