Hurricane Nolo is forecast to cross the International Date Line this weekend and be redesignated Typhoon Nolo by the Japan Meteorological Agency. The storm weakened to a tropical storm after a week of activity in the Central Pacific. It remains active and is expected to move into the western North Pacific basin by Oct 5-6, 2026.
The Weather Company forecast on Oct 2, 2026 states Nolo will keep its name. NBC News reported the same transition.
What is Happening Now
Current status of Hurricane Nolo after weakening to tropical storm
Nolo weakened from hurricane strength to a tropical storm in the Central Pacific. It continues to track west-northwest. The system is monitored by the Central Pacific Hurricane Center.
Forecast track toward the International Date Line
Model guidance shows a westward track toward 180 degrees longitude. The storm is projected to approach the boundary between the Central and Western Pacific basins over the weekend.
Expected timing of basin crossing into Western North Pacific
Crossing is expected within 48 to 72 hours from Oct 4, 2026. The handoff from Central Pacific to Western Pacific responsibility will occur at the International Date Line.
Nolo Changes from a Hurricane to a Typhoon After Crossing the International Date Line
The same system will be called a typhoon after crossing the International Date Line. The name Nolo stays the same. Only the classification term changes with the basin.
Why the Name Stays the Same But the Classification Changes
Hurricane vs Typhoon: Same storm, different basin terminology
Hurricane, typhoon and cyclone refer to the same phenomenon. The term depends on the ocean basin. The Western North Pacific uses typhoon.
Role of the Central Pacific Hurricane Center and Japan Meteorological Agency
The Central Pacific Hurricane Center issues advisories east of the Date Line. The Japan Meteorological Agency becomes the primary agency west of the Date Line. The Joint Typhoon Warning Center provides parallel tracking.
Why Hurricane Nolo could become a typhoon this weekend, not a new storm
Basin boundaries do not create a new storm. Nolo will be tracked continuously. The designation changes from tropical storm to typhoon based on intensity and location.
| Agency | Basin Responsibility | Current Designation | Post-Crossing Designation |
|---|---|---|---|
| Central Pacific Hurricane Center | Central Pacific | Tropical Storm Nolo | Hand off |
| Japan Meteorological Agency | Western North Pacific | N/A | Typhoon Nolo |
| Joint Typhoon Warning Center | Western North Pacific | Monitor | Typhoon Nolo |
Why Hurricane Nolo Could Become a Typhoon This Weekend
International Date Line Crossing Explained
How the International Date Line defines the Eastern and Western Pacific basins
The International Date Line at 180 degrees longitude marks the administrative boundary for tropical cyclone naming. East of the line is the Central Pacific basin. West of the line is the Western North Pacific basin.
What happens to storm tracking and naming at the boundary
Tracking continues without interruption. Advisories are transferred between agencies. The storm identifier is retained to avoid confusion.
Western Pacific Conditions for Typhoon Development
Sea surface temperatures and wind shear in the Western North Pacific
The Western North Pacific typically offers warm sea surface temperatures in October. Wind shear conditions will determine intensification after the transition.
Potential intensification or weakening after transition
Forecasts indicate possible re-intensification if conditions remain favorable. Weakening is also possible with increased shear. The track remains offshore.

Track Map and Model Consensus
NHC vs JTWC forecast comparison
NHC Central Pacific guidance shows a steady west-northwest motion. JTWC anticipates the system entering the western basin as a tropical storm to typhoon. Consensus points to no landfall on Hawaii.
Landfall risk for Hawaii, Japan, and Pacific islands
No direct landfall risk for Hawaii is indicated. Japan is far from the projected track. Remote Pacific islands may see distant swells.
Impact and Safety Considerations
What the transition means for warnings and advisories
Warnings will be issued by JMA after the crossing. Public advisories will continue under the same name. The change is administrative.
How to track Typhoon Nolo after the name change
Track via JMA, JTWC and NHC updates. Use official advisory numbers. Do not rely on unofficial renames.
Key Takeaways for Tracking Cross-Basin Storms
Common misconceptions about hurricane to typhoon name changes
A storm does not get a new name at the Date Line. The name persists across basins. Only the regional term changes.
Where to get real-time updates for Typhoon Nolo
Monitor Central Pacific Hurricane Center until handoff. Then follow Japan Meteorological Agency and Joint Typhoon Warning Center. Official advisories provide position, intensity and forecast track.
💡 Frequently Asked Questions (FAQ)
- Q: Will Hurricane Nolo keep its name after becoming a typhoon?
- A: Yes. The system will retain the name Nolo. Only the classification term changes from hurricane to typhoon after entering the Western North Pacific basin.
- Q: When is Nolo expected to be redesignated as Typhoon Nolo?
- A: Model guidance and The Weather Company forecast a basin crossing within 48 to 72 hours from Oct 4, 2026, around Oct 5-6, 2026.
- Q: Why does the storm change from hurricane to typhoon?
- A: The classification changes because the system moves from the Central Pacific basin monitored by the Central Pacific Hurricane Center to the Western North Pacific basin where the Japan Meteorological Agency uses the term typhoon.
- Q: Is Nolo still a threat as it tracks west-northwest?
- A: Nolo weakened from hurricane strength to a tropical storm but remains active and is being monitored as it approaches the International Date Line.
