Hawaii officials urged residents and visitors on Sunday to prepare for heavy rains, flooding, and possibly mudslides as Hurricane Lowell, a major Category 3 storm, approached the islands.

The National Hurricane Center, based in Miami, issued a tropical storm warning for two islands on Sunday. The warning highlights the expected impacts from the powerful hurricane, which has already reached major storm status.

Preparation efforts focus on ensuring safety ahead of the anticipated weather conditions. Residents are advised to secure property, stock supplies, and follow local guidance to minimize risks from flooding and related hazards.

Hurricane Lowell's strength as a Category 3 system brings significant concerns for heavy rainfall that could lead to flash flooding in vulnerable areas. Mudslides remain a possibility in hilly or mountainous regions where saturated ground could give way.

The tropical storm warning from the National Hurricane Center serves as a formal alert for the affected islands. It signals that tropical storm conditions are expected within the warned areas, prompting proactive measures by local authorities and the public.

Officials continue to monitor the storm's path and intensity closely. Updates from the Miami-based center will provide further details as conditions evolve over the coming hours and days.
