Potential Tropical Cyclone One-C Approaches Hawaii with Flood Risks

The National Hurricane Center (NHC) has identified a system approximately 1,000 miles east-southeast of Honolulu, Hawaii, as Potential Tropical Cyclone One-C (PTC 1-C). This system is expected to strengthen into Tropical Storm Hernan by Friday, August 14, 2026. Heavy rainfall is forecast to begin on the Big Island on Friday, spreading to Maui and other Hawaiian Islands over the weekend. Rainfall totals could range from 5 to 10 inches across much of the island chain, with localized areas potentially receiving up to 20 inches. Gusty winds may accompany the rain bands, posing risks of downed trees and power lines. The system is predicted to be a strong tropical storm as it nears Hawaii, with the possibility of landfall as a hurricane. Source time: Wed, 12 Aug 2026 22:43:16 GMT.

Potential Tropical Cyclone One-C Targets Hawaii with Rare Landfall Threat

Potential Tropical Cyclone One-C Targets Hawaii with Rare Landfall Threat

Tropical activity in the Pacific Ocean has intensified as former Invest 93C has been upgraded to Potential Tropical Cyclone One-C, aiming toward Hawaii later this week. The National Hurricane Center has issued official track forecast cones, watches, and warnings for Hawaii, anticipating the system's development into a tropical depression or storm. Currently located over 1,000 miles southeast of the Big Island, the system is expected to intensify into a tropical storm or hurricane before making landfall. Elevated tides, strong winds, and heavy rainfall are forecast, with wave heights potentially exceeding 30 feet. This marks a rare event, as the last hurricane to make landfall in Hawaii was Category 4 Iniki in 1992, which caused significant damage.

Potential Cyclone Development Threatens Hawaii with Severe Weather

Potential Cyclone Development Threatens Hawaii with Severe Weather

Meteorologists are closely monitoring a potential tropical cyclone developing approximately 1100 miles east-southeast of the Hawaiian Islands. The National Hurricane Center's latest Tropical Weather Outlook suggests that the system could develop further by mid-week, potentially impacting Hawaii's weather significantly. A high-pressure system currently maintains trade wind weather across the state, but this could change dramatically if the cyclone approaches. Additionally, multiple south swells are expected, with the largest swell anticipated on Wednesday. The potential cyclone could also generate a significant east/southeast swell later in the week, posing risks to coastal areas.

The National Hurricane Center (NHC) is closely monitoring an area of low pressure, designated as Invest 93C, located approximately 1,100 miles southeast of the Big Island of Hawaii. This system is expected to organize into a tropical depression and potentially strengthen into Tropical Storm Lala later this week. Forecast models suggest that Lala could approach the Hawaiian Islands this weekend, with its exact track and intensity still uncertain. Scenarios range from the storm passing north or south of the islands to a direct impact. The system is being closely watched as it could bring significant weather impacts to Hawaii.

The National Hurricane Center is monitoring a potential tropical cyclone approximately 1,100 miles east-southeast of the Hawaiian Islands. Development of this system is expected by midweek, with the possibility of significant impacts on Hawaii's weather. A high-pressure system to the northeast is currently maintaining trade wind weather across the state. However, the forecast could change dramatically if the system moves closer to the islands. Additionally, multiple south swells are anticipated this week, with the largest swell near advisory levels expected on Wednesday. The potential cyclone may also generate a sizeable east/southeast swell later in the week. (Source time: Mon, 10 Aug 2026 13:19:22 GMT)
