Tuesday, Aug. 21 2018, 6:30 PM: Civil Defense Update

The Central Pacific Hurricane Center has issued a Hurricane Warning for Hawai‘i County. A Hurricane Warning is issued when hurricane conditions of damaging winds, damaging surf and flooding rains are possible within 36 hours.

The Central Pacific Hurricane Center reports as of 5 p.m., Hurricane Lane is a Category 4 hurricane located approximately 375 miles SSE of Kailua-Kona with sustained winds of 155 mph, moving WNW at approximately 9 mph.

Due to the Hurricane Warning, the following advisories have been issued:

  • A high surf warning with extreme ocean surges and large breaking waves is in effect for south-facing shores of Ka‘ū and Kona.
  • A flash flood watch is in effect for the island of Hawaii. Do expect possible heavy rain leading to flash flooding.
  • Hurricane force winds are possible on the west side of the island from South Point to Kohala on Thursday. The remainder of the island could experience tropical storm force winds.

Due to the Hurricane Warning status, the following closures are in effect:

  • All public schools and the University of Hawai‘i campuses will be closed until further notice.
  • All beach parks from South Point north to Kohala will be closed until further notice. All pavilion and camping permits for these parks have been cancelled.
  • South Point Road from the Kamaoa Road junction to South Point is closed to all traffic.

The Division of Boating and Ocean Recreation (DOBOR) advises all boat owners in unprotected harbors from Milolii to Mahukona to take all measures to secure their vessels. This includes removal, if possible. Complete all actions before nightfall Wednesday.

The Department of Education, in coordination with the American Red Cross and Hawai‘i County Parks and Recreation, have identified shelters in all districts that will be opened if necessary. You will be notified if any of the shelters are opened.

6:15 PM: UH Campuses Closed

The State of Hawai‘i announced on Aug. 21 at 5:20 p.m. that all government offices and facilities in Maui and Hawai‘i Island (Big Island) counties are closed starting Wednesday, August 22, due to the threat of Hurricane Lane, a category 4 storm currently on track to move dangerously close the islands. That means all University of Hawai‘i campuses and non-essential university operations on Hawai‘i Island, Maui, Moloka‘i and Lana‘i will be closed starting tomorrow morning until further notice. Please stand by for updates as UH campuses and non-essential operations on O‘ahu and Kaua‘i may also close as the storm approaches. Residence halls at UH Hilo will remain open for student residents.

Hurricane Lane could make landfall on any or multiple islands, and may bring strong winds, heavy rains, flooding, high surf and storm surges. All students, faculty and staff are asked to keep informed of the latest developments and prepare for the possibility of the need to shelter in place or move to a public shelter. Prepare yourself and your families for the potential effects of the storm. Officials recommend a 14-day emergency supply.

Students in residence halls will receive more specific communications and instructions from their respective student housing office. However, do not hesitate to contact them with any questions or concerns at UH Mānoa: (808) 956-8177; UH Hilo: (808) 932-7403.

All members of the UH community are urged to sign up for UH Alert to receive emergency text alerts. If you have already signed up, log in to ensure that your contact information is up-to-date.

5:53 PM: Hurricane Lane 370 Miles South of Hilo

Powerful Hurricane Lane, located about 325 miles to the south- southeast of South Point on the Big Island at 5 p.m., has been on a WNW track during the day today.

Lane is expected to turn toward the NW on Wednesday, followed by a turn toward the NNW on Thursday.

On this forecast track, the center of Lane will move dangerously close to or over the main Hawaiian Islands from Thursday through Saturday.

Although some weakening is expected the next couple of days, Lane is forecast to remain a dangerous hurricane as it draws closer to the Hawaiian Islands.

The onset of damaging tropical storm force winds on the Big Island could be as early as Wednesday evening, with dangerous hurricane force winds possible by Thursday.

On Maui County, damaging tropical storm force winds could begin as early as Wednesday night, with dangerous hurricane force winds possible starting late Thursday.

On O‘ahu, damaging tropical storm force winds could begin as early as Thursday, with dangerous hurricane force winds possible starting late Thursday night.

Rainbands and thunderstorms surrounding Lane will begin to overspread the state from south to north, reaching the Big Island late tonight or Wednesday morning. Torrential rainfall is possible as squalls increase when Lane makes its closest approach, which could lead to major flash flooding, landslides and mudslides. Flooding can occur even in areas not usually prone to flooding. Storm total rainfall amounts greater than 20 inches are possible.

Swell generated by Lane will bring very large and rough surf and dangerous rip currents for south and southeast facing shores. Surf heights of 15 to 25 feet could lead to ocean water surging and sweeping
over beaches, coastal benches, lava flows, and roadways, creating the potential for significant damage to coastal properties and infrastructure, including roadways. Coastal evacuations and road closures are possible. Large breaking waves may affect harbor entrances and channels with damage possible to docks, piers, ramps, and boats.

Tornadoes and large waterspouts will be possible as Lane approaches the islands, mainly along and to the right of the track of the hurricane on Thursday and Friday.

5:17 PM: All Big Island Libraries Closed

All public libraries and support offices on Hawai‘i Island, Maui, Lāna‘i and Moloka‘i will be closed on Wednesday, Aug. 22 in anticipation of the potential threat of Hurricane Lane.

All library programs statewide scheduled from Wednesday, Sunday, Aug. 22 to 26 are cancelled.

For more information, visit the Hawai‘i State Public Library System’s website.

  • 14.3N 153.2W
  • Storm Intensity 155 mph
  • Movement WNWt or 285 degrees at 9 mph

Hurricane Lane is passing to the south-southeast of the Big Island today and is expected to begin a turn northwest toward the islands tonight and Wednesday. The center of Lane will track dangerously close to, or over the islands Thursday through Saturday. Regardless of the exact track of the center, major impacts are likely in some areas as the hurricane makes it’s closest approach. It is important to remember, these impacts can extend far from the center.

The onset of damaging tropical storm force winds on the Big Island could be as early as Wednesday afternoon or evening, with dangerous hurricane force winds possible by Wednesday night. On Maui County, damaging tropical storm force winds could begin as early as Wednesday night, with dangerous hurricane force winds possible starting on Thursday. Hurricane Watches may be needed for other areas as Lane draws closer.

Bands of intense showers and thunderstorms surrounding Lane will begin to overspread the state from south to north, reaching the Big Island late tonight or Wednesday morning. Excessive rainfall is possible which could lead to major flash flooding, landslides and mudslides. Flooding can occur even in areas not usually prone to flooding. Storm total rainfall amounts greater than 20 inches are possible.

Swell generated by Lane will bring very large and rough surf and dangerous rip currents for south and southeast facing shores.

Tornadoes and large waterspouts will be possible associated with Lane, mainly along and to the right of the track of the hurricane.

11 AM: Dangerous Hurricane Lane Moves WNW Toward Hawai‘i 

A Hurricane Watch is still in effect for Hawai‘i and Maui County.

A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical storm-force winds, conditions that make outside preparations difficult or dangerous.

Additional Tropical Storm or Hurricane Watches will likely be issued this afternoon or tonight.

At 11 a.m., the center of Hurricane Lane was located near latitude 14.3 north, longitude 153.2 west.

Lane is moving toward the WNW near 9 mph and this motion is expected to continue through tonight.

A turn toward the northwest is expected Wednesday into Thursday.

On the forecast track, the center of Lane will move very close to or over the main Hawaiian Islands from Thursday through Saturday.

Maximum sustained winds are near 155 mph with higher gusts. Lane is a powerful Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.

Slow weakening is forecast during the next 48 hours, but Lane is forecast to remain a dangerous hurricane as it draws closer to the Hawaiian Islands.

Hurricane-force winds extend outward up to 40 miles from the center and tropical-storm-force winds extend outward up to 140 miles.

HAZARDS AFFECTING LAND

WIND: Tropical storm conditions are possible within the Hurricane Watch area beginning Wednesday night, with hurricane conditions possible on Thursday.

RAINFALL: Excessive rainfall associated with Lane is expected to affect portions of the Hawaiian Islands from Wednesday into the weekend, leading to flash flooding and landslides. Lane is expected to produce total rain accumulations of 10 to 15 inches with isolated maximum amounts of 20 inches over the Hawaiian Islands.

SURF: Large swells generated by Lane will impact the Hawaiian Islands, beginning tonight on the Big Island and spreading across the remainder of the island chain Wednesday through Thursday. These swells will produce large and potentially damaging surf along exposed west, south and east-facing shorelines.

9:30 AM: ‘Hawai‘i Should Prepare for Lane Now’

The Weather Channel has provided an update on Hurricane Lane, a potentially dangerous and destructive Category 4 storm currently headed toward the Hawaiian islands.

“Even if its center does not make landfall, and despite the forecast of weakening, Hurricane Lane could bring damaging winds, power outages, and life-threatening and destructive flooding rains and waves to portions of all of the Hawaiian Islands,” said TWC Hurricane Expert Dr. Rick Knabb.

“Today and Wednesday are important days of preparation throughout the state of Hawai‘i since tropical storm conditions could first start arriving by late Wednesday night or Thursday morning. It does not take a direct hit for a hurricane to be deadly, and water has historically taken the most lives in hurricanes and tropical storms.”

He said Hawai‘i must prepare now for the storm and the potentially lengthy aftermath.

8 AM: Hurricane Lane Winds Upped to Near 155 MPH

At 8 a.m., the eye of Hurricane Lane was located near latitude 14.1 north, longitude 152.6 west.

Lane is moving toward the west near 9 mph and this general motion is expected to continue through tonight, with a slight decrease in forward speed.

A turn toward the northwest is expected Wednesday into Thursday.

On the forecast track, the center of Lane will pass close to Hawa‘i and Maui Counties on Thursday and Thursday night.

Maximum sustained winds have increased to near 155 mph with higher gusts.

Lane remains a powerful Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.

Slight weakening is expected during the next couple of days, but Lane is forecast to remain a dangerous hurricane as it draws closer to the Hawaiian Islands.

Hurricane-force winds extend outward up to 40 miles from the center and tropical-storm-force winds extend outward up to 140
miles.

7:30 AM: Hurricane Lane May Pose Major Threat to Hawai‘i

A Hurricane Watch is in effect for the Big Island.

Category 4 Hurricane Lane is 430 miles SSE of Hilo at 14.1 N ,152.3 W.

PRECAUTIONARY/PREPAREDNESS ACTIONS

EVACUATIONS: Listen to local officials for recommended preparedness actions, including possible evacuation. If ordered to evacuate, do so immediately.

OTHER PREPAREDNESS INFORMATION

Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business.

When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, and tornadoes extend well away from the center of the storm.

If in a place that is vulnerable to high wind, such as near large trees, a manufactured home, upper floors of a high-rise building, or on a boat, plan to move to safe shelter.

If you live in a place particularly vulnerable to flooding, such as near the ocean or a large inland lake, in a low-lying or poor drainage area, in a valley, or near an already swollen river, plan to move to safe shelter on higher ground.

Always heed the advice of local officials and comply with orders that are issued. Do not needlessly jeopardize your life or the lives of others.

When securing your property, outside preparations should be concluded as soon as possible before conditions deteriorate. The onset of strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

Be sure to let friends and family members know of your intentions for weathering the storm and your whereabouts. Have someone located away from the threatened area serve as your point of contact. Share vital contact information with others. Keep cell phones handy and charged.

Check on those who may not be fully aware of the situation or who are unable to make personal preparations.

If you are a visitor, know the name of the island on which you are located and where it is relative to current watches and warnings. If staying at a hotel, ask the management staff about their onsite disaster plan. Listen for evacuation orders, especially pertaining to area visitors.

Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast.

There is a threat from tornadoes with this storm. Have multiple ways to receive Tornado Warnings. Be ready to shelter quickly.

6 AM: Hurricane Lane About 450 Miles SSE of Kailua-Kona

The National Weather Service has issued a Hurricane Watch for Hawai‘i County. A Hurricane Watch is issued when hurricane conditions of damaging winds, damaging surf, and flooding rains are possible within 48 hours.

The Central Pacific Hurricane Center reports as of 5 am, Hurricane Lane is a Category 4 hurricane located approximately 450 miles SSE of Kailua-Kona with sustained winds of 150 mph, moving west at approximately 12 mph.

Hurricane Lane Watch, Aug. 21, 2018, 5:24 a.m. NOAA map

Due to the Hurricane Watch, the following advisories have been issued:

  • Hurricane force winds are possible throughout the island on Thursday.
  • Expect heavy rain leading to flash flooding and landslides.
  • Large swells with potentially damaging surf along south and west facing shores of Puna, Ka‘ū, and Kona.
  • Residents along affected shores should be alert for high and dangerous surf conditions. Boat owners, take measures to secure your vessel.

The following closures are in effect:

  • Whittington and Punaluu Beach Parks remain closed. All pavilion and camping permits for these parks have been cancelled.
  • South Point Road from the Kamaoa Road junction to South Point is closed to all through traffic; open to local residents only.
  • The Department of Education reports that all schools are open.

Take this time to assure that family and business emergency plans are up to date.

5:39 AM: Flood Watch in Effect for All Islands Starting Wednesday AM

As Hurricane Lane approaches the islands from the south, deep tropical moisture associated with Hurricane Lane will spread across the island chain from the east, with increased potential for heavy
rainfall.

The National Weather Service in Honolulu has issued a Flash Flood Watch for the Big Island, Kaho‘olawe, Kaua‘i, Lanai, Maui, Molokai, Ni‘ihau and O‘ahu from Wednesday morning through Friday afternoon.

Abundant moisture from Hurricane Lane is expected to move over the Big Island late Wednesday and spreading to the rest of the islands through Friday. Intense rainfall will be possible, especially along southeast and east facing slopes. The risk of flooding will only increase as Hurricane Lane approaches.

In addition to flood prone areas, heavy rain events of this size may cause flooding in areas outside of designated flood zones.  Low spots in roads will become dangerous and impassible due to severe runoff. High amounts of debris in streams and gulches maymclog bridges and culverts resulting in dangerous flooding outside the normal channels and significant property damage.

PRECAUTIONARY/PREPAREDNESS ACTIONS

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION.

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

4:48 AM: Hurricane Lane Watch in Effect for Hawai‘i & Maui Counties

Lane Local Watch/Warning Statement/Advisory Number 27, National Weather Service Honolulu

At 5 a.m., the eye of Hurricane Lane was located by satellite near latitude 14.1 North, longitude 152.3 West.

Lane is moving toward the west near 12 mph and this motion is expected to continue through tonight, with a slight decrease in forward speed.

A turn toward the northwest is expected Wednesday into Thursday.

On the forecast track, the center of Lane will pass close to Hawai‘i and Maui Counties on Thursday.

Cone of probability, Hurricane Lane, Aug. 21, 2018, 5 a.m. NOAA map

Lane is a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Slight weakening is expected the next couple of days, but Lane is forecast to remain a dangerous hurricane as it draws closer to the Hawaiian Islands.

Hurricane-force winds extend outward up to 40 miles from the center and tropical-storm-force winds extend outward up to 140 miles.

Lane’s current maximum sustained winds are between 150 and 240 mph.

WIND: Hurricane conditions are possible within the Hurricane Watch area on Thursday.

RAINFALL: Excessive rainfall associated with Lane is expected to affect portions of the Hawaiian Islands from Wednesday into the weekend, leading to flash flooding and landslides. Lane is expected to produce total rain accumulations of 10 to 15 inches with isolated maximum amounts of 20 inches over the Hawaiian Islands. Showers and thunderstorms with gusty winds may occur.

SURF: Large swells generated by Lane will impact the Hawaiian Islands this week. These swells will produce large and potentially damaging surf along exposed south and west facing shorelines.

POTENTIAL IMPACTS

  • Damage to porches, awnings, carports, sheds and unanchored mobile homes. Unsecured lightweight objects blown about.
  • Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over.
  • A few roads impassable from debris, particularly within urban or heavily wooded places.
  • Hazardous driving conditions on bridges and other elevated roadways.
  • Scattered power and communications outages.
  • Potential for moderate flooding rain.
