Wider weather episode

A strong low that passed a few hundred miles north of the state produced gale force winds and heavy rainfall over all of the main Hawaiian Islands. The worst flooding affected O'ahu during the daylight hours of January 30 and southwest Maui that night. The Kuli'ou'ou and Hawai'i Kai areas appeared to have the worst flooding on O'ahu due to the passage of an intense rain band with 2- to 4-inch per hour rain rates. On Maui, the southwestern flank of Haleakala received 3 to 6 inches of rain, and the southeastern side had 3 to 11 inches. Flooding caused considerable damage in Kihei as several normally dry gulches overflowed. Most of South Kihei Road was closed due to the flooding, and numerous businesses and residences were impacted. The main rain band shifted to the Big Island during the early morning hours of January 31. Most of the rainfall occurred over the western half of the island, with widespread totals of 2 to 5 inches but no reports of significant flood damage.
