Kaua‘i County officials on Tuesday, April 7, urged vigilance for Garden Isle community members and visitors because of potential severe weather conditions persisting into the weekend — and possibly beyond.
National Weather Service forecasts a notable shift in the weather pattern for Kauaʻi and the rest of the island chain as a developing low-pressure system northwest of the state pulls deep tropical moisture northward, bringing strengthening southerly winds, widespread showers and the potential for thunderstorms from midweek through the weekend.
Periods of heavy rain are possible, particularly as a moisture band lingers near the island, and conditions are expected to become more organized and impactful Wednesday through Friday, April 8-10.
Forecasters already issued a flood watch for the county that is in effect through Friday afternoon.
Soils remain saturated from recent heavy rains, including from back-to-back kona lows in mid-March. Any bursts of intense rainfall could quickly lead to runoff, rising streams and localized flooding, so residents are urged to stay weather aware as this unsettled pattern settles in.
Gusty southerly winds could also increase later in the week, especially near heavier showers and along exposed and windward areas.
County services and facilities might close with little to no notice, depending on severity of the incoming storm and its effects.
Kūhiō Highway near Hanalei Bridge also could be closed with little or no advance notice, particularly if a flash flood warning is issued. Utilities and other services also could be disrupted.
That portion and area of the roadway remains open for now.
County, state and federal officials will continue to monitor the situation and actively coordinate in preparation for this potential event.
Officials remind the public to use 9-1-1 only for life-threatening or time-critical emergencies. Calls to 9-1-1 for weather updates or general road conditions can significantly delay emergency response.
Call 808-241-1725 for road statuses and closures. Report non-emergency road hazards by calling Kaua‘i Police Department dispatch at 808-241-1711.
Call the National Weather Service automated line at 808-245-6001 or visit the Honolulu forecast office website for important weather information including any advisories, watches and warnings, if issued.
Kaua‘i Island Utility Cooperative standard tips to prepare for power outages
- Use surge protectors to protect your appliances and equipment.
- Turn off and unplug all unnecessary appliances or equipment.
- Keep a portable battery-powered radio and flashlights with extra batteries.
- Stay away from downed power lines and report to 9-1-1.
- Contact the utility co-op at 808-246-4300 to update your contact information and receive alerts.
The public is also advised to check conditions before venturing out for hiking, river or beach excursions.
River and stream crossings, recreational trails and other outdoor recreation areas could quickly become hazardous. Emergency rescues might not be possible during severe weather.
Do not cross swollen rivers or streams; always check with a lifeguard at any lifeguard station before entering the ocean — know before you go.
Speak with a Kaua‘i County lifeguard, visit the Safe Beach Day website or call Kaua‘i Ocean Safety Bureau at 808-241-4984 for up-to-date information about Kaua‘i ocean conditions and safety.
Officials also advise the public to be aware of potentially heavy ponding across various portions of the island.
Kaua‘i County Public Works Roads Division is actively working to clear drains and perform other proactive storm mitigation measures.
Hawai‘i Department of Health Clean Water Branch also previously issued brown water advisories from Lydgate Beach to Wailuā Beach and from Nāwiliwili to Kalapaki Beach because of possible contamination following past heavy rainfall.
