Rain showers, heavy at times, marked by occasional claps of thunder, caused the National Weather Service to issue a flood watch Tuesday afternoon.
As of Tuesday night, the flood watch was in place until 4 a.m. this morning.
Today heavy showers are again forecast, with some clearing by Thursday. However, more heavy showers are being forecast for the weekend.
The flood watch for Kaua’i means conditions are favorable for heavy rainfall and flooding, though flooding is not imminent.
Kaua’i residents living in low-lying areas near streams and rivers were warned to be prepared to take quick action. Drivers were warned to be alert on the alert for flooding, and warned not to cross rising water along roads.
At 4:30 p.m. on Tuesday a rainfall weather map showed the South Shore and West Side coastlines receiving the bulk of the rain from the storm, with Ni’ihau also receiving rain from the storm.
A report from Waimea Valley Tuesday afternoon said the Waimea River was running higher than normal, but not flooding.
The slow-moving, moist and unstable air mass that arrived over Kaua’i is part of the weather system that flooded the North Shore of O’ahu on Monday. So far, rainfall totals have been light on Kaua’i compared to the drenching O’ahu and the Big Island have experienced over the past few days. Over seven inches of rain was recorded at some of the hardest hit locations on O’ahu on Monday.
Kamehameha Highway from Wahiawa to Hale’iwa on the North Shore of O’ahu *was closed for six hours Monday morning due to dangerous muddy road conditions. The Ka’u District of the Big Island saw over four days of rain from the system, with six inches of rain in a 24-hour period ending Monday afternoon.
In addition to the rainy weather, a sizable south swell is expected to hit the South Shore beginning today with wave faces reaching 15 or 16 feet by Saturday, with a possibility of 20-foot faces according to veteran University of Hawai’i surf forecaster Pat Caldwell.
