Recent Storm Impacts and Current Vulnerabilities
Hawaii is still recovering from Hurricane Lala, which caused extensive mudslides and power outages on the Big Island, and from Hurricane Lowell, which struck Kauai on Sept. 7. The recent damage has left many communities, especially in the Ka‘u District, more susceptible to flash flooding and wind-related hazards.
Forecast Details and Expected Impacts
Remnants of Tropical Depression 15-E are situated southeast of the islands. The National Oceanic and Atmospheric Administration’s National Hurricane Center assigns a 90 % chance the system will redevelop into a tropical depression this week and a 60 % chance of further organization within 48 hours. Models show the disturbance could move slowly west-northwestward, bringing 3–5 inches of rain to windward and southeast portions of the Big Island by late Wednesday, with potential totals ranging from a few inches up to 2 feet by week’s end. Summit wind gusts may reach 70 mph on the Big Island and 60 mph on Haleakala. Flood watches for the Big Island and possibly Maui are under consideration.
Official Guidance and Community Preparations
John Bravender, warning coordination meteorologist for the National Weather Service, warned that rainfall amounts could vary widely and that a slow-moving storm would increase flood risk. Hawaii County Mayor Kimo Alameda emphasized the “major concern” of another heavy-rain event in areas already hit by Lala and urged residents to stay informed and ready. Civil-defense spokesperson Adam Weintraub said agencies are meeting daily with the weather service, deploying support to Naalehu, and urging residents to secure supplies, trim vegetation, and avoid narrow, wet roads.

- “If it does get bad, we’re encouraging people to make that trip before the weather gets heavy because you’d much rather be on some of those narrow, winding roads when it’s dry rather than once the rain actually starts coming,” — Adam Weintraub, civil defense spokesperson
What’s Next
The National Weather Service will continue to refine the storm’s track over the next 48 hours. A community meeting in Naalehu scheduled for Wednesday night may be postponed if forecasts indicate a closer approach. Residents are advised to monitor official updates, prepare emergency kits for at least two weeks, and be ready for potentially lengthy power outages.
