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. $$ Blood
