US · Published Oct 5, 2026
• An upper-level low to the northwest of Hawaii is forecast to bring southerly winds and deep tropical moisture over the islands by midweek.
• Breezy trade winds will persist on Monday with limited showers, but conditions are expected to change starting late Tuesday.

Impact & Risks

The incoming tropical moisture and heavy rainfall could lead to localised flooding and disruptions in affected areas. Southerly winds may bring unstable weather conditions, impacting outdoor activities and travel. Coastal areas may experience moderate surf due to swells generated by Super Typhoon Choi-Wan, particularly on west-facing shores of Hawaii Island. Mariners and beachgoers should exercise caution.
