HURRICANE LANE – INFRASTRUCTURE IMPACT SUMMARY
ASSESSMENT
The Department of Homeland Security (DHS)/National Protection and Programs Directorate/National
Risk Management Center (NRMC) assesses low to medium impacts to infrastructure on the Hawaiian
Islands because of high winds and potential storm surge from Hurricane Lane. Regional impacts may occur,
but no national impacts are anticipated.
As of August 22, 2018,1400 EDT (0800 HST), Hurricane Lane is a powerful Category 4 hurricane located approximately
445 miles south-southeast of Honolulu, HI and moving toward the west-northwest at approximately 8 miles per hour
(mph). Hurricane Lane is anticipated to move very close to or over the main Hawaiian Islands from Thursday, August 23,
through Saturday, August 25. Maximum sustained winds are near 155 mph with higher gusts. Hurricane-force winds extend
outward up to 40 miles (65 km) from the hurricane’s center, and tropical storm-force winds extend outward up to 140
miles (220 km). Hurricane Lane is forecasted to slightly weaken but remain a dangerous hurricane as it approaches the
Hawaiian Islands. Hurricane Lane is expected to produce 10 to 15 inches of rain over the Hawaiian Islands, with localized
amounts in excess of 20 inches.

(0800 HST), AUGUST 22, 2018
The analysis within this document focuses on potential impacts resulting from wind damage and electrical power outages. If
future forecasts for Hurricane Lane predict significant storm surge inundation, NRMC would anticipate higher levels of
physical damage to facilities within inundation zones.
As of August 22, 2018, 1400 EDT (0800 HST), the duration of impacts across sectors cannot be assessed with significant
fidelity because of forecast uncertainty. NRMC will continue to monitor.

NRMC is not aware of any asset disruption within the affected area that would result in a national impact. Furthermore,
NRMC has not identified any materials produced in Hawaii that are used in significant amounts by the rest of the United
States. Since 2014, exports from Hawaii have accounted for no more than 0.1 percent of total U.S. exports annually
according to the U.S. Census Bureau.i

INFRASTRUCTURE LEVEL IMPACT: LOW MEDIUM HIGH

IMPACT
LEVEL
Some loss of coverage resulting from disruptions of electric power
service and infrastructure damage (tower and antenna) from high
winds is anticipated. Backup batteries and backup generator power
Communications could be insufficient if power outage recovery times exceed fuel
availability and resupply. Low physical impacts are expected to
undersea cable landing stations as they are reinforced concrete
structures and will likely resist wind damage.
Electric Power: High winds could cause damage to overhead
transmission and distribution assets. High winds may also cause
damage to residential generation sources (such as solar panels on
homes). Large-scale generation resources, such as petroleum
generation, should not be affected.
Fuel: Hawaii reports that there is at least a 7-day supply of fuel
Energy available on each of the main islands. Hawaii Electric has a 30-day
fuel supply available for generation. The two refineries on Oahu are
reported to have a 7-day supply of crude oil and are shutting down
as a precaution in advance of the storm. Barbers Point Harbor on
the island of Oahu is the primary entry point for bulk shipments of
crude and refined products.
Water: Disruptions of electric power service could result in
limited operations at water treatment facilities. If drinking water
systems are unable to maintain sufficient pressure in the water
Food, Water, distribution system, boil water notices will be issued to ensure the
Shelter safety of the supply. Some locations could lose water availability if
pumping and lift stations lack backup generation or run out of fuel.
Food and Agriculture: Transportation disruptions may delay
regular food distribution.
Strong damaging winds and heavy rainfall could result in debris and
flooding conditions on the roadways. Weather delays and
cancellations across the island airports are expected to occur.
Damage to facilities and aids to navigation could occur because of
Transportation higher than normal wave action. U.S. Coast Guard will close ports
once gale force winds are expected within 12 hours. Limited
damage to port facilities and waterways is anticipated from this
event. U.S. Coast Guard will determine when waterways will return
to an operational status.
Hospitals may lose power, but will use backup generators to
provide power until the storm passes. Generators will require
Health and Medical refueling if hospitals experience extended power outages. Minimal
physical damage is anticipated. The Department of Health and

Human Services reports that hospitals have ordered extra medical
supplies in anticipation of supply chain disruptions.
Emergency Services: Operations are likely to be hindered by
telecommunications network outages and transportation
disruptions. If electric outages persist, fuel supplies may need to be
replenished at Emergency Services facilities to continue operations.
Safety and Security Dams: There is concern with the Ka Loko Dam and the Upper
Helemano Dam for overtopping, as both assets are near capacity
and may require releases of water. Downstream impacts to lifeline
infrastructure are unlikely.
Hazardous Waste No known infrastructure in the impacted area.
