...FLOOD WATCH IN EFFECT FOR ALL HAWAIIAN ISLANDS THROUGH 6 PM HST MONDAY... * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...The state of Hawaii. * WHEN...Through Monday afternoon. * IMPACTS...Significant flooding may occur due to excessive rainfall and overflow of streams and drainages. Roads in several areas may be closed, along with property damage in urban or low lying spots due to runoff. Landslides may also occur in areas with steep terrain. * ADDITIONAL DETAILS... - Low pressure northwest of the islands will draw deep tropical moisture northward bringing a high likelihood of heavy rainfall capable of causing flash flooding, especially given saturated antecedent conditions due to recent rainfall. The heaviest rain is expected over Molokai, Oahu, and Kauai.

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
