Description
* LOCATIONS AFFECTED
- Hilo
- Pahoa
- Volcano
* WIND
- LATEST LOCAL FORECAST: Below tropical storm force wind
- Peak Wind Forecast: 20-30 mph with gusts to 40 mph
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for wind 58
to 73 mph
- The wind threat has remained nearly steady from the
previous assessment.
- PLAN: Plan for dangerous wind of equivalent strong tropical
storm force.
- PREPARE: Remaining efforts to protect life and property
should be completed as soon as possible. Prepare for
significant wind damage.
- ACT: Move to safe shelter before the wind becomes hazardous.
- POTENTIAL IMPACTS: Significant
- Some damage to roofing and siding materials, along with
damage to porches, awnings, carports, and sheds. A few
buildings experiencing window, door, and garage door
failures. Mobile homes damaged, especially if unanchored.
Unsecured lightweight objects become dangerous projectiles.
- Several large trees snapped or uprooted, but with greater
numbers in places where trees are shallow rooted. Several
fences and roadway signs blown over.
- Some roads impassable from large debris, and more within
urban or heavily wooded places. A few bridges, causeways,
and access routes impassable.
- Scattered power and communications outages, but more
prevalent in areas with above ground lines.
* STORM SURGE
- LATEST LOCAL FORECAST: Localized storm surge possible
- Peak Storm Surge Inundation: The potential for 1-3 feet
above ground somewhere within surge prone areas
- Window of concern: Begins this afternoon
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm
surge flooding greater than 1 foot above ground
- The storm surge threat has remained nearly steady from the
previous assessment.
- PLAN: Plan for storm surge flooding greater than 1 foot
above ground.
- PREPARE: Complete preparations for storm surge flooding,
especially in low-lying vulnerable areas, before conditions
become unsafe.
- ACT: Leave immediately if evacuation orders are given for
your area.
- POTENTIAL IMPACTS: Limited
- Localized inundation with storm surge flooding mainly along
immediate shorelines and in low-lying spots, or in areas
farther inland near where higher surge waters move ashore.
- Sections of near-shore roads and parking lots become
overspread with surge water. Driving conditions dangerous
in places where surge water covers the road.
- Moderate beach erosion. Heavy surf also breaching dunes,
mainly in usually vulnerable locations. Strong rip currents.
- Minor to locally moderate damage to marinas, docks,
boardwalks, and piers. A few small craft broken away from
moorings.
* FLOODING RAIN
- LATEST LOCAL FORECAST: Flood Watch is in effect
- Peak Rainfall Amounts: Additional 8-12 inches, with locally
higher amounts
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for major
flooding rain
- The flooding rain threat has decreased from the previous
assessment.
- PLAN: Emergency plans should include the potential for
major flooding from heavy rain. Evacuations and rescues are
likely.
- PREPARE: Strongly consider protective actions, especially
if you are in an area vulnerable to flooding.
- ACT: Heed any flood watches and warnings. Failure to take
action will likely result in serious injury or loss of life.
- POTENTIAL IMPACTS: Extensive
- Major rainfall flooding may prompt many evacuations and
rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, arroyos,
and ditches may become dangerous rivers. In mountain areas,
destructive runoff may run quickly down valleys while
increasing susceptibility to rockslides and mudslides.
Flood control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or
washed away. Many places where flood waters may cover
escape routes. Streets and parking lots become rivers of
moving water with underpasses submerged. Driving conditions
become dangerous. Many road and bridge closures with some
weakened or washed out.
* TORNADO
- LATEST LOCAL FORECAST:
- Situation is somewhat favorable for tornadoes
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for a few
tornadoes
- The tornado threat has remained nearly steady from the
previous assessment.
- PLAN: Emergency plans should include the potential for a
few tornadoes.
- PREPARE: If your shelter is particularly vulnerable to
tornadoes, prepare to relocate to safe shelter before
hazardous weather arrives.
- ACT: If a tornado warning is issued, be ready to shelter
quickly.
- POTENTIAL IMPACTS: Limited
- The occurrence of isolated tornadoes can hinder the
execution of emergency plans during tropical events.
- A few places may experience tornado damage, along with
power and communications disruptions.
- Locations could realize roofs peeled off buildings,
chimneys toppled, mobile homes pushed off foundations or
overturned, large tree tops and branches snapped off,
shallow-rooted trees knocked over, moving vehicles blown
off roads, and small boats pulled from moorings.
