Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Sun Oct 25 2026
For the eastern and central North Pacific east of 180 longitude:
Active Systems:
The National Hurricane Center is issuing advisories on Hurricane Vance, located a few hundred miles southwest of Acapulco, Mexico.
Western Central Pacific:
Showers and thunderstorms continue to show signs of organization with an area of low pressure just crossing the International Date Line, several hundred miles west of Johnston Atoll. Earlier satellite wind data indicated that the circulation was also becoming better defined. If these current trends continue, the system is likely to become a tropical depression, possibly as soon as later today. The system is moving towards the east-northeast at 10 to 15 mph and will slowly approach the Johnston Atoll later this week. By the middle of the week, however, strong upper-level winds should limit additional development of the system.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.
