As residents returned to their damaged homes, forecasters and authorities warned that flood advisories were still in effect on Monday, March 23.

City officials say crews and partner agencies have been working to respond to impacts from the recent Kona low.

Now the cleanup begins in earnest after the brunt of the latest Kona-low storm — the second such weather event in a week — walloped Oahu, Maui County and Hawaii Island early Friday and again Saturday,

The worst flooding to hit Hawaii in two decades swept homes off their foundations, floated cars out of driveways and left floors, walls and counters covered in thick, reddish volcanic mud.

The already battered Hawaiian islands may face more flooding today, with a flood watch still in effect for the Big Island and a flood advisory in Maui issued through Monday afternoon

Oahu, Hawaii's most populous island, and Maui, were hit hardest by the storms.  No deaths have been reported, Molly Pierce, a spokesperson for Oahu’s department of emergency management, said Sunday afternoon.

"We are asking the public to please stay away unless you live or work in the area or are involved in active recovery efforts."

The Coast Guard was conducting search and rescue efforts for residents whose homes may have been washed away by the floods, Hawaii's governor said.

Hundreds of people have been rescued as severe flooding batters Hawaii’s Oahu island, prompting evacuation orders near a dam officials feared could overtop as water levels rose.
