Latest on Hurricane Lane and impacts on Hawaii

Good morning, before we get to the latest information on Hurricane Lane that continues its approach to the Hawaiian Islands, here is the latest on Hurricane Watches and Warnings…

A Hurricane Warning is in effect for…


Maui County…including the islands of Maui, Lanai, Molokai and Kahoolawe

Hawaii County

A Hurricane Watch is in effect for…

Kauai County…including the islands of Kauai and Niihau

A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm- force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion.

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.

At 11 pm, Hawaiian Time, the eye of Hurricane Lane is located about 350 miles south of Honolulu.  Lane is moving slowly to the northwest near 7 mph and this slow motion is expected to continue with a turn to the north-northwest, then a turn to the north is expected by Friday before turning back west by Saturday.  On the forecast track, Lane will come dangerously close to the main Hawaiian Islands today into Friday.  Maximum sustained winds are near 145 mph.  Lane is an extremely dangerous category 4 hurricane.  Some slow weakening is forecast, but Lane will remain a hurricane for the next few days.  Slide11

As you can see above the official forecast on the track of Lane, it is expected to gradually turn to the north-northwest later today and to the north by Friday as Lane gets dangerously close to the Hawaii, the timing of the turn to the west is very critical as it could move over the island of Oahu if the turn to the west can do not occur before getting to the island.  Once the turn to the west do occur by Saturday, it would parallel the Hawaiian island chain.  A look at the radar, you can see the eye well defined south of the Hawaiian islands, with outer rainbands affecting the Big Island, where there have been reports of a foot of rain have already fell.  Flash Flood Warnings are in effect for Hawaii County.Slide7

Impacts on the Hawaiian Islands…

Rainfall/Flooding…Rain will continue to overspread the Hawaiian Islands today through Friday, with very heavy rainfall occurring at times.  Rainfall totals of 10 to 20 inches, with localized amounts of 30 to 40 inches will be possible.  Life threatening flash flooding and mudslides will be possible as Lane will be slow moving and hours upon hours of heavy rainfall is expected.

Winds…Tropical storm force winds will also continue to spread across the Big Island today, with hurricane force winds for the Big Islands to occur as early as tonight or early Friday morning.  Tropical storm force winds could reach Maui County as early as this afternoon, with hurricane force winds possible by late tonight or early Friday morning.  For Oahu, tropical storm force winds could begin late tonight into Friday morning, with hurricane force winds possible by Friday afternoon or Friday night.

Storm Surge/Surf…With the slow movement of Lane, large and destructive winds will pound the Hawaiian Islands for several days, which in turn could actually increase coastal flooding concerns, especially for south and west facing beaches.  Storm Surge flooding of 2 to 4 feet on top of battering waves will be possible.

Tornadoes/Waterspouts…A few tornadoes and/or waterspouts will be possible, especially on the northeast quadrant of Lane.

Those who have family or interests in Hawaii, time is quickly running out for the Big Island, all preparations should be near completion this morning, and preps on the other islands should be complete by the end of today!  Slide12

The final portion of this blog is on other preparedness information from the National Weather Service…

Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding.

If you are relocating to safe shelter, leave as early as possible. Allow extra time to reach your destination. Many roads and bridges will be closed once strong winds arrive. Check the latest weather forecast before departing and drive with caution.

Failure to adequately shelter may result in serious injury or loss of life. Always heed the advice of local officials and comply with any orders that are issued. Remember, during the storm 9 1 1 Emergency Services may not be able to immediately respond if conditions are unsafe. This should be a big factor in your decision making.

Keep cell phones well charged. Cell phone chargers for automobiles can be helpful, but be aware of your risk for deadly carbon monoxide poisoning if your car is left idling in a garage or other poorly ventilated area.

It is important to remain calm, informed, and focused during an emergency. Be patient and helpful with those you encounter.

If you are a visitor, be sure to know the name of the city or town in which you are staying and the name of the county or parish in which it resides. Listen for these locations in local news updates. Pay attention for instructions from local authorities.

Rapidly rising flood waters are deadly. If you are in a flood-prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, turn around don`t drown!

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, consider moving to a safer shelter before the onset of strong winds or flooding.

Closely monitor, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings.
