2024 Hurricane Season Summary for the Central Pacific Basin

The 2024 hurricane season featured two tropical cyclones in the Central Pacific Hurricane Center (CPHC) area of responsibility. Four to five tropical cyclones occur during an average year. Hurricane season runs from June 1 to November 30. The central Pacific basin extends from 140°W to the International Date Line.

Hurricane Hone was the first tropical cyclone of the season in the central Pacific, developing about 1,000 miles east-southeast of the Big Island on August 22. This was the first tropical cyclone to form in the central Pacific since Tropical Storm Ema in October 2019. Hone continued to strengthen as it approached the state, eventually becoming a hurricane late on August 24 just over 50 miles south-southeast of Ka Lae, the southern tip of the Big Island. Hone weakened to a Tropical Depression on August 29, then strengthened to a Tropical Storm again from August 30-September 1. During this time a Tropical Storm Watch was issued for Kure and Midway Atolls and portions of the Papahānaumokuākea Marine National Monument from Lisianski Island to Pearl and Hermes Atoll. Hone became extratropical just after crossing the International Date Line on September 1.

Hurricane Gilma moved into the basin from the east on August 27 and rapidly weakened before dissipating east of Hawaiʻi.

Impacts to the State of Hawaiʻi: Heavy rain from Hurricane Hone caused flash flooding that damaged homes and closed several roads across Hawaii County on August 25, leading to several million dollars in damage. Tropical storm force winds brought down trees and utility poles on the Big Island, with reports of damage on Maui and Oahu as well.

Western Pacific, Indian Ocean, and adjacent Seas:

>>> There’s an area of disturbed weather being referred to as Invest 99B, which is located approximately 174 NM east-northeast of Colombo, Sri Lanka

Animated enhanced infrared satellite imagery (eir) depicts a consolidating llcc with persistent convection embedded within a monsoon trough. A microwave image depicts fragmented, formative banding along the western semicircle. Another pass indicates the area of convection has become more symmetrical with 30 knot winds within the western and southern portion of the circulation.

Environmental analysis indicates a favorable environment for further development with good upper-level divergence, warm sea surface temperatures, symmetric 850 mb vorticity and a migration toward a lower shear environment to the north.

Global deterministic models are in good agreement that Invest 99B will consolidate and strengthen over the next 24 hours.

Maximum sustained surface winds are estimated at 28 to 33 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours remains high.

>>> There’s a second area of disturbed weather being referred to as Invest 96S, which is located approximately 260 NM west-northwest of Cocos Islands.

Animated enhanced infrared satellite imagery (eir) depicts a broad area of disorganized persistent convection. An animated multi-spectral satellite imagery depicts a very broad area of dense, persistent convection with fragmented rain bands beginning to organize.

The environment is marginally favorable for development with conducive warm sea surface temperatures and a strong 850 mb vorticity value, as well as robust radial divergence aloft this is offset by moderate to high (20-25 knot) vertical wind shear.

Global deterministic models are in agreement that Invest 96S will consolidate and drift poleward over the next 24 to 48 hrs.

Maximum sustained surface winds are estimated at 28 to 33 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.
