...TROPICAL STORM WATCH REMAINS IN EFFECT...
* LOCATIONS AFFECTED
- Puuwai
* WIND
- LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind
- Peak Wind Forecast: 30-40 mph with gusts to 60 mph
- Window for Tropical Storm force winds: Monday afternoon
until early Tuesday morning
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for wind 39
to 57 mph
- The wind threat has remained nearly steady from the
previous assessment.
- PLAN: Plan for hazardous wind of equivalent tropical storm
force.
- PREPARE: Efforts to protect property should now be
underway. Prepare for limited wind damage.
- ACT: Act now to complete preparations before the wind
becomes hazardous.
- POTENTIAL IMPACTS: Limited
- 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.
* 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: Monday afternoon until Tuesday 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: Efforts should now be underway to prepare for
storm surge flooding, especially in low-lying vulnerable
areas.
- ACT: Take actions to protect life and property. Prepare to
leave 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 4-8 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 remained nearly steady 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 favorable for tornadoes
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for several
tornadoes
- The tornado threat has remained nearly steady from the
previous assessment.
- PLAN: Emergency plans should include the potential for
several tornadoes with a few possibly intense having larger
damage paths.
- PREPARE: Those living in manufactured homes or on boats
should prepare to relocate to safe shelter before hazardous
weather arrives.
- ACT: Listen for tornado watches and warnings. If a tornado
warning is issued, be ready to shelter quickly.
- POTENTIAL IMPACTS: Significant
- The occurrence of scattered tornadoes can hinder the
execution of emergency plans during tropical events.
- Several places may experience tornado damage with a few
spots of considerable damage, power loss, and
communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped
or uprooted, vehicles tumbled, and small boats tossed
about. Dangerous projectiles can add to the toll.

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 6-10 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 remained nearly steady 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 favorable for tornadoes
- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for several
tornadoes
- The tornado threat has remained nearly steady from the
previous assessment.
- PLAN: Emergency plans should include the potential for
several tornadoes with a few possibly intense having larger
damage paths.
- PREPARE: Those living in manufactured homes or on boats
should prepare to relocate to safe shelter before hazardous
weather arrives.
- ACT: Listen for tornado watches and warnings. If a tornado
warning is issued, be ready to shelter quickly.
- POTENTIAL IMPACTS: Significant
- The occurrence of scattered tornadoes can hinder the
execution of emergency plans during tropical events.
- Several places may experience tornado damage with a few
spots of considerable damage, power loss, and
communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped
or uprooted, vehicles tumbled, and small boats tossed
about. Dangerous projectiles can add to the toll.
