Police Advisories

  • Police are advising the public to remain off the streets and roadways in the South Hilo District due to extreme weather from Hurricane Lane that is causing flooding and heavy runoff. Do not drive on the roadways and streets unless absolutely necessary.
  • All county parks are closed due to the weather conditions.  County crews are posting signs and barricades at problem areas.  Do not enter these high-risk areas.
  • Avoid Kaalaiki Road (Ka‘u), just above (mauka) of Naalehu Town, road closed due to flooding.

Flash Flood Warning

At 9:15 p.m. HST, weather radar and rain gauges continue to show areas of heavy rain along the windward and southeast sections of Hawaii Island, with the heaviest rains focusing upslope of Hilo in the Wailuku River valley, and along the slopes of Hamakua coast from Laupahoehoe to Honokaa. Flash flooding is ongoing across the warned area, with Hawaii County Civil Defense reporting that evacuations are occurring in the Reeds Island area of Hilo along the Wailuku River. Water levels on the Wailuku River and Honolii Stream remain very high, with the level on the Wailuku River having risen about 5 feet between 6 p.m. and 9 p.m. HST. Daniel K. Inouye Highway (Route 200/Saddle Road) is currently closed near the 10.5 mile marker above Hilo due to a landslide. Bands of heavy rain will continue moving into Hawaii Island during the night. THIS IS A VERY DANGEROUS SITUATION. AVOID UNNECESSARY TRAVEL.

Locations in the warning include, but are not limited to, Hilo, Naalehu, Paauilo, Waipio Valley, Orchidlands Estates, Kukuihaele, Hawi, Pepeekeo, Keaau, Honokaa, Ookala and Hawaiian Paradise Park.

This warning may need to be extended beyond 12:45 a.m. HST Friday (Aug 24) if heavy rain persists.


Campers and hikers should avoid low lying flood prone areas. People should stay away from streams, drainage ditches and low lying areas prone to flooding. The rainfall and runoff will cause hazardous driving conditions due to ponding, reduced visibility, and poor braking action. Excessive runoff may cause rockslides and mudslides in steep terrain. Remember, if lightning does threaten your area, the safest place to be is indoors.

Debris in streams and gulches may clog bridges and culverts resulting in flooding outside normal water channels causing damage.

Do not cross fast flowing or rising water in your vehicle or on foot. Turn around, don’t drown.
