The National Weather Service has extended the flood advisory for windward and southeast sections of the Big Island until at least 1:30 p.m.

Posted 10 a.m.:

For Big Island residents, the liquid sunshine just keeps coming.

Instability caused by a passing low-pressure system has given way to “abundant” low-level moisture, the National Weather Service said this morning.

That resulted in the weather service issuing eight successive flood advisories for the Big Island over an 18-hour period, each one an extension of the one before.

The latest was issued at 7:14 a.m. today and is in effect until 10:30 a.m.

But don’t bet against yet another extension. Or two or three.

Over the weekend, rainfall gauges around the island tallied at most several inches of rain from the low-pressure system that arrived on Friday.

But they took a jump Monday and into this morning, with nine gauges registering 4 inches or more of rain in the 24-hour period ending at 8 a.m. today.

Driven by trade winds and enhanced by the now-departed low-pressure trough that moved to the east, nearly all were located on the windward side, from Puna to Hilo to Hamakua, with a few in the Saddle between Mauna Loa and Mauna Kea.

Hilo’s airport topped the list with 6.39 inches, followed by Laupahoehoe with 5.68.

Forecasters said the heavy showers are expected to diminish later in the week, just in time for another round of rain as more unsettled weather arrives in the form of a front moving across the state Saturday and Sunday.
