Weather Alerts
Hydrologic Outlook issued March 7 at 3:17AM 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.
Hydrologic Outlook issued March 7 at 3:24PM HST by NWS Honolulu HI
ESFHFO A large low pressure system developing northwest of the state the next couple of days will pull a very moist southern air mass northward across the state. This will likely initiate periods of heavy rain and occasional thunderstorms that will increase the probabilities of flooding over Kauai County late Monday into Monday night. The flooding threat will likely expand eastward and envelope the entire state from Tuesday into the later part of next week. The flooding potential may persist into next weekend or early the following week. It is too early to forecast rain totals or the exact timing and location of the greatest flooding potential. Stay weather aware the next several days as this system develops and the details of the impacts from it come into better focus. The next couple of days would be a good time to clear storm drains and culverts of debris, 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.
