Current Snapshot

The Pacific Disaster Center’s (PDC Global) Thursday, April 11, 2024, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas

Current Tropical Cyclones:

Tropical Cyclone 22P (Paul) …is located approximately 636 NM east of Cairns, Australia – Final Warning

Northeast Pacific Ocean:

The North Pacific hurricane season officially ended on November 30, 2023. Routine issuance of the Tropical Weather Outlook will resume on May 15, 2024. During the off-season, Special Tropical Weather Outlooks will be issued as conditions warrant.

The eastern Pacific basin hurricane season was above normal, with 17 named storms, of which 10 were hurricanes and eight of those major hurricanes.

From August 16 to 21, Tropical Storm Hilary brought widespread heavy rainfall and flooding to Southern California, with some areas receiving up to 600% of their normal August rainfall. Hilary resulted in the first ever issuance of Tropical Storm Watches and Warnings for the Southern California coastline by NOAA’s National Hurricane Center. In addition, the Center distributed key hazard focused messages for Hilary in Spanish through the agency’s new language translation project.

Hurricane Otis made landfall near Acapulco, Mexico, on October 25 as a category-5 hurricane, with sustained winds of 165 mph. Otis holds the record as the strongest land falling hurricane in the eastern Pacific, after undergoing rapid intensification in which wind speeds increased by 115 mph in 24 hours.

Central North Pacific:

The central North Pacific hurricane season officially ended on November 30, 2023. Routine issuance of the Tropical Weather Outlook will resume on June 1, 2024. During the off-season, Special Tropical Weather Outlooks will be issued as conditions warrant.

The central Pacific basin had a near-normal season with four tropical systems traversing the basin.

Hurricane Dora, a category-4 storm, passed south of Hawaii in early August, marking the first major hurricane in the central Pacific basin since 2020. The strong gradient between a high pressure system to the north and Dora to the south was a contributing factor to the wind-driven, fast-moving wildfires in Hawaii.

Western Pacific, Indian Ocean and adjacent Seas

Southwest Pacific Ocean…

Tropical Cyclone 22P (Paul) – Final Warning

According to the JTWC warning number 6, sustained winds are 35 knots…with gusts to near 45 knots

Tropical cyclone 22P has weakened slightly over the past six hours, with fragmented core convection. Animated enhanced infrared satellite imagery depicts a compact system, with deep convection flaring along an elongated line due to increasing westerly vertical wind shear.

A bullseye image shows sharp cyclonic turning, with 30-35 knot winds near a weakly defined center, but also shows easterly flow over the northern semicircle disrupting the system’s overall wind field. This weakening or disruption of the core is evident in a microwave image, which reveals weak banding and two distinct clusters of deep convection over the south and west quadrants.

Tropical cyclone 22P is forecast to slow and turn westward, as a low- to mid-level subtropical ridge builds to the south. After 12 hours, TC Paul will accelerate west-northwestward to northwestward under strong southeasterly trade flow. TC 22P will weaken quickly due to dry air entrainment and increasing (30 to 35 knot) vertical wind shear, with dissipation expected by 36 hours.
