Felicia bringing much-needed rain to islands


POSTED: Wednesday, August 12, 2009

All islands except the Big Island received beneficial rain last night from former tropical depression Felicia but heavier showers could develop in the next 24 hours, the National Weather Service reported today.

There is still some potential for flash flooding, said Derek Wroe, lead forecaster at the Honolulu Forecast Office.

Just before 10 a.m., the National Weather Service issued a flash flood watch for Oahu, Maui, Lanai, Molokai and Kauai through late tonight. A watch means conditions may develop that lead to flash flooding. A flash flood warning will be issued if conditions worsen.

Remnants of the one-time hurricane were centered near Maui this morning and moving slowly west across the islands and could bring heavy rainfall this afternoon and evening, Wroe said.

Kauai had an inch of rain or less in most windward areas overnight and Oahu had from half an inch to more than 3 inches in wetter areas.

In 12 hours ending at 8 a.m., an Oahu forest gauge near Waiahole in the Koolau range recorded 6.34 inches, upper Nuuanu had 3.54 inches, and the Lyon Arboretum in Manoa had 3.76 inches.

Ulupalakua had the highest rain reading on Maui for the 12-hour period with 2.73 inches. Most other areas had under an inch of rain.

The  Big Island had some localized rain, with 2.72 inches at Kealakekua, but little in other areas.
