Weather Alerts
Hydrologic Outlook issued March 6 at 3:01PM HST by NWS Honolulu HI
ESFHFO A strong low pressure system will develop northwest of the state over the weekend, bringing deep moisture into the area. The potential for heavy rains, thunderstorms, and flash flooding will develop over Kauai County late Monday into Monday night, spreading eastward to the entire state Tuesday and Wednesday. This potential could easily last into next weekend, and perhaps even beyond. It is too soon to forecast rainfall totals or exact timing and locations of maximum flash flooding potential. Stay weather aware over the weekend as this system comes into better focus and details become available. Now would be a good time to clean out storms drains and culverts, or anything else that can block the flow of water. Keep up to date with the latest forecast information through the Internet (weather.gov/hawaii), local media, social media, or NOAA Weather Radio broadcasts. An updated outlook will be issued by 5 AM HST Saturday March 7th 2026 or sooner if necessary.
