Flood Watch
...FLOOD WATCH IN EFFECT THROUGH SUNDAY AFTERNOON FOR ALL ISLANDS IN THE STATE OF HAWAII... * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...The island of Oahu in Honolulu County, Maui, Molokai, Lanai, Kahoolawe, and the Big Island. * WHEN...Through Sunday afternoon. * IMPACTS...Significant flooding may occur due to the overflow of streams and drainages.

Hydrologic Outlook
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.
