Hurricane Nolo is expected to bring heavy showers to the eastern end of the state over the next few days. The exact track of the dangerous tropical cyclone remains somewhat uncertain, but significant heavy rain is likely over windward and southeast Big Island. * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Big Island, Maui, Lanai, Molokai, and Kahoolawe. * WHEN...Through Saturday afternoon. * IMPACTS...Significant flooding may occur due to the 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... - Deep moisture on the north side of Hurricane Nolo will bring heavy showers to the Big Island, and to a lesser extend to Maui through the Saturday. Windward and southeast Big Island, and windward Maui, are the most likely to experience heavy rain due to the slow moving system, with considerable flooding possible over the remaining portions of Big Island and Maui today and Saturday. The remainder of Maui County has a lower possibility of flooding, but remains at risk.
