The National Weather Service has issued a Flood Watch for the Island of Maui, in effect from 6:00 p.m. Saturday through 6:00 p.m. Monday. This advisory may need to be extended if heavy rain persists. The approaching storm is the first named weather system in the 2014 Central Pacific Hurricane Season. The storm, named Wali, is expected to briefly attain tropical storm force winds before weakening as it approaches the islands.
EFFECTS: Deep tropical moisture combined with an upper level trough will bring the threat of heavy rain and thunderstorms from Saturday night through Monday. Enhanced showers will reach the windward big island and Maui Saturday night, and the rest of the state Sunday.
Unstable conditions from an upper trough and deep tropical moisture will bring the threat of heavy showers and thunderstorms. Localized intense rainfall is likely to occur with the potential for flash flooding. The greatest chance of flooding will occur over windward slopes, with a lesser chance over leeward locations.
PRECAUTIONARY MEASURES: A FLASH FLOOD WATCH MEANS THAT CONDITIONS MAY DEVELOP THAT LEAD TO FLASH FLOODING. FLASH FLOODING IS VERY DANGEROUS. REMEMBER THAT IT DOES NOT HAVE TO BE RAINING HEAVILY WHERE YOU ARE FOR FLASH FLOODING TO OCCUR. AVOID CAMPING OR HIKING NEAR STREAMS AND LOW LYING FLOOD PRONE AREAS.
