HONOLULU (HawaiiNewsNow) - Heavy rain drenched many parts of Kauai and Oahu Sunday, with forecasters predicting the possibility of more of the same through Tuesday.
Meantime, the National Weather Service said a Flash Flood Watch remained posted for all islands, except the Big Island of Hawaii, through Monday afternoon.
Flash Flood Warnings were issued for Kauai and Oahu Sunday morning as downpours began to cause flooding in streams and other low-lying areas.
Here are some of the more significant rainfall totals for the last 12 hours, ending at 11 a.m. Sunday, in inches:
The wet weather is being caused by a an upper level low pressure system over the islands, which is causing unstable conditions. The low is forecast to move away to the northwest, but a deepening upper level trough nearby may keep our weather unsettled for the next couple of days.
The weather system may also bring snow to the upper levels of the summits of Mauna Loa and Mauna Kea on the Big Island of Hawaii. A Winter Weather Advisory is posted for those areas until 6 p.m. Sunday.
The Severe Weather Team at Hawaii News Now will keep you posted with the latest developments.
