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.

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.

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.

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.
