Event Summary: Tropical Cyclone DOLPHIN-26
Tropical Cyclone DOLPHIN-26 is assessed as having a low humanitarian impact (GDACS Green Alert). Although the system underwent rapid intensification into a violent Super Typhoon (Category 5 equivalent) over the Western Pacific Ocean, its track has remained mostly over open water away from densely populated landmasses.

Impact Assessment Factors
Maximum Sustained Wind Speed:
Dolphin experienced extreme rapid intensification in late July 2026, reaching Category 5 Super Typhoon strength with wind speeds exceeding 260 km/h. However, these peak destructive forces were concentrated almost exclusively over open ocean waters.
Exposed Population:
Due to its trajectory north-northwest through the open Pacific, the storm bypassed major population centers. The number of people exposed to Category 1 hurricane-force winds or higher remained negligible.
Vulnerability & Coastal Risks:
While small island communities like the Marshall Islands maintain high structural and infrastructural vulnerability, storm surge and wind hazards associated with Dolphin were localized to minor swell activity and minor wave impacts. No widespread structural damage or major humanitarian crises were recorded on land.
