EARLIER COVERAGE
A flood watch is in effect for all Hawaiian Islands today through Monday afternoon due to the possibility of flash flooding caused by excessive rainfall, according to the National Weather Service.
A deepening Kona low north of Kauai is expected to move southwest today and Monday before turning west. Thunderstorms and heavy showers will affect the region over the next couple days leading to the flash flood threat. Winds may strengthen to wind advisory levels Monday for lower elevations and high wind warnings on Hawaii island summits. Lingering moisture may keep rain over the state through the week.

“Flood prone roads and other low lying areas may be closed due to elevated runoff and overflowing streams,” according to the forecast. “Urban areas may receive more significant flooding and property damage due to rapid runoff. Significant flooding may occur due to the overflow of streams and drainages. Landslides may also occur in areas with steep terrain.”
The greatest flood risk is along the southeastern mountain slopes of Maui and Hawaii counties as deep moisture spreads up the slopes.
The flood watch may be extended into Tuesday if weather conditions persist.
Flood advisories are also in effect for Hawaii County until 10:45 a.m. today, while Maui County will remain in effect until 11:30 a.m. today.
At 7:45 a.m. today, the Hawaii island radar indicated heavy rain traveling over portions of Puna and Kau coasts. Rain was falling at a rate of 1 to 2 inches per hour, with isolated heavier rainfall rates of 3 inches per hour between Pahala and Pahoa including areas of Pahoa Kalapana Road and Highway 11.
Some locations that will experience flooding include Hilo, Hawaii Volcanoes National Park, Volcano, Glenwood, Mountain View, Wood Valley, Hawaiian Acres, Pahala, Orchidlands Estates, Keaau, Pahoa, Punaluu Beach, Kawa Flats, Papaikou, Naalehu, and Fern Forest.
At 8:19 a.m. today, the Maui County radar showed heavy rain continuing to develop and move over the eastern portions of the island. Rain was falling at a rate of 1 to 2 inches per hour with the highest rates and totals found in the upslope areas between Kaupo and Nahiku.
Some locations that will experience flooding include Kipahulu, Kaupo, Hana, Haleakala National Park and Hamoa.

A small, medium period south swell will continue to steadily fade into Saturday, allowing surf along south and west-facing shores to drop a notch. A series of small, medium to long period south and southeast swells will fill in Saturday into the first half of next week, which will boost surf heights back near seasonal averages.
Tiny surf will prevail along north-facing shores through most of the coming week as only some limited short-period energy reaches the islands from the north. Trade winds remain lighter than normal through the weekend, keeping surf along east-facing shores below average. East shore surf will begin to trend up early next week as trade winds increase upstream and across the region.

Principal honors Obama as ‘Child of Hawaii’ at library opening – AsAmNews
The honor of introducing former President Barack Obama at the grand opening of his new presidential library in Chicago Thursday went to Dr. Kaiwipunikauikawēkiu Punihei Lipe of Hawaii.
Hawaii News Now reports that Lipe participated in the inaugural cohort of the Asia-Pacific Leaders Program in 2019 and is currently the principal at Kamehameha Schools Kapālama.
“Where I come from, to introduce someone means we have pilina, a connection. If this man walked into my home, my children would call him uncle because we are both keiki o ka ʻāina, children of Hawaii,” she said in her remarks.
She told those in attendance that the former president and herself are both “children of Hawaii.” Obama lived on the island and attended Punahou School and lived in Hawaii for eight years until his graduation from high school.
Lipe said being children of Hawaii carries with it a “sacred responsibility to care for those who we may never meet.”
She made reference to the resilient Hawaiian shrub, the Like a’ali’i.
“The a’ali’i thrives by being deeply rooted, resilient through storm and drought, and fiercely responsive. That is what ‘yes, we can’ means to my indigenous heart. It demands that we remain unshakably rooted in truth, resilient through trial, and so responsive that just as this plant yields its leaves for medicine, its blooms for beauty, and its timber for protection, we become the healing, the vibrance, and the shelter needed by our communities and by grandmother earth.”
