The continued downpours in Hawaii raised the threat of “significant and life-threatening flooding,” and the National Weather Service in Honolulu issued a warning Monday night, saying some areas could see as much as one foot of rain within 48 hours.

Hawaiian islands could suffer “catastrophic flooding” from a storm system lasting through Tuesday, the National Weather Service told Hawaii.

There’s been about one meter of rain in the past 24 hours in Kula, Maui, according to the National Weather Service (NWS) in Honolulu.

A large area of Oahu was hit by up to 2 inches of rain per hour Monday, and another area of heavy rain is also expected in the hours ahead, with rainfall of up to 3 inches per hour expected.

On the Big Island, at any given point during the past 24 hours, eight inches of rain fell.

The statement authorized the use of funds to “support state and county efforts in providing quick and efficient relief of suffering, damage, and losses caused by flooding and other effects of heavy rains,” Ige wrote on Twitter.

Landslides are expected and some motorways can be closed due to floods and landslides that could cut communities off from the outside world.

A flood warning was in place for all of the Hawaiian islands until Tuesday afternoon local time.
