SITUATION OVERVIEW
------------------
TROPICAL STORM HONE, LOCATED ABOUT 125 MILES SOUTH-SOUTHEAST OF HILO
AT 5 PM HST THIS AFTERNOON, IS FORECAST TO MOVE TOWARD THE WEST FOR
THE NEXT SEVERAL DAYS, WITH SOME STRENGTHENING POSSIBLE TONIGHT.
ALONG THE FORECAST TRACK, THE CENTER OF HONE WILL PASS JUST SOUTH OF
THE BIG ISLAND TONIGHT AND SUNDAY MORNING AND WILL MOVE OFF TO THE
WEST OF THE AREA EARLY NEXT WEEK.
RAINFALL OF 2 TO 4 INCHES HAS ALREADY FALLEN ACROSS WINDWARD BIG
ISLAND TODAY, AND HEAVIER SHOWERS ARE MOVING IN AS HONE NEARS. BANDS
OF ADDITIONAL HEAVY SHOWERS AND THUNDERSTORMS WILL AFFECT THE BIG
ISLAND TONIGHT AND WILL BRING A THREAT OF FLASH FLOODING TO THE
ENTIRE BIG ISLAND INTO SUNDAY, THOUGH THE GREATEST POTENTIAL WILL BE
ACROSS THE HAMAKUA, HILO, PUNA, AND KAU DISTRICTS. STORM TOTAL
RAINFALL ESTIMATES THROUGH SUNDAY RANGE FROM 6 TO 12 INCHES WITH
LOCALLY HIGHER AMOUNTS POSSIBLE. A FEW LINGERING THUNDERSTORMS AND
HEAVY SHOWERS MAY DEVELOP OVER PORTIONS OF BIG ISLAND ON MONDAY,
MAINLY OVER LEEWARD AND UPSLOPE AREAS. SEE THE LATEST FLOOD WATCH FOR
MORE DETAILS.
PORTIONS OF THE BIG ISLAND HAVE ALREADY SEEN SUSTAINED WINDS AROUND
30 MPH AND GUSTS OVER 50 MPH, WHILE A FEW SITES IN AND AROUND KOHALA
RANCH HAVE GUSTED OVER 60 MPH. THESE WINDS WILL CONTINUE TO INCREASE
THIS EVENING AND WILL LIKELY BE LOCALLY DAMAGING. TROPICAL STORM
CONDITIONS, WITH SUSTAINED WINDS OVER 39 MPH AND GUSTS IN EXCESS OF
60 MPH, ARE EXPECTED TONIGHT INTO EARLY SUNDAY, ESPECIALLY FOR AREAS
DOWNSLOPE FROM HIGHER TERRAIN, OVER HEADLANDS, AND THROUGH PASSES.
THIS INCLUDES AREAS LIKE THE HUMUULA SADDLE, THE WAIMEA SADDLE,
LEEWARD KOHALA, AND SOUTH POINT.
LARGE SHORT PERIOD SWELL PRODUCED BY HONE WILL BUILD THROUGH THE
EVENING AND PEAK TONIGHT, MAINLY ALONG EAST AND SOUTHEAST SHOWERS OF
THE BIG ISLAND. THE LARGE SWELLS WILL SPREAD ACROSS THE OTHER PORTIONS
OF THE ISLAND CHAIN TONIGHT AND SUNDAY, PRODUCING LIFE-THREATENING
SURF AND RIP CURRENTS. A HIGH SURF WARNING IS IN EFFECT FOR THE BIG
ISLAND.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE NOW UNFOLDING ACROSS
THE BIG ISLAND. REMAIN WELL GUARDED AGAINST LIFE-THREATENING FLOOD
WATERS HAVING POSSIBLE EXTENSIVE IMPACTS, MAINLY OVER WINDWARD AREAS.
IF REALIZED, THESE IMPACTS INCLUDE:
- 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.
* WIND:
POTENTIAL IMPACTS FROM THE MAIN WIND EVENT ARE NOW UNFOLDING ACROSS
THE BIG ISLAND. REMAIN WELL SHELTERED FROM DANGEROUS WIND HAVING
POSSIBLE SIGNIFICANT IMPACTS. IF REALIZED, THESE IMPACTS INCLUDE:
- 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.
* TORNADOES:
POTENTIAL IMPACTS FROM TORNADOES ARE NOW UNFOLDING ACROSS THE BIG
ISLAND. REMAIN WELL BRACED AGAINST A TORNADO EVENT HAVING POSSIBLE
LIMITED IMPACTS. IF REALIZED, THESE IMPACTS INCLUDE:
- 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.
* OTHER COASTAL HAZARDS:
EAST SWELLS ASSOCIATED WITH HONE WILL BRING HIGH AND ROUGH SURF AND
STRONG RIP CURRENTS TO EAST AND SOUTHEAST-FACING SHORES OF BIG
ISLAND INTO SUNDAY. A HIGH SURF WARNING IS IN EFFECT FOR EAST AND
SOUTHEAST FACING SHORES OF BIG ISLAND.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
FOLLOW THE ADVICE OF LOCAL OFFICIALS.
* OTHER PREPAREDNESS INFORMATION:
NOW IS THE TIME TO STAY INSIDE. LISTEN FOR UPDATES AND BE READY IN
CASE YOU LOSE ELECTRICAL POWER. KEEP A BATTERY-POWERED RADIO,
CHARGED CELL PHONE AND FLASHLIGHT HANDY.
WHEN MAKING SAFETY AND PREPAREDNESS DECISIONS, DO NOT FOCUS ON THE
EXACT FORECAST TRACK SINCE HAZARDS SUCH AS FLOODING RAIN, DAMAGING
WIND GUSTS, STORM SURGE, AND TORNADOES EXTEND WELL AWAY FROM THE
CENTER OF THE STORM.
IF YOU LIVE IN A PLACE PARTICULARLY VULNERABLE TO FLOODING, SUCH AS
A LOW-LYING OR POOR DRAINAGE AREA, PLAN TO MOVE TO SAFE SHELTER ON
HIGHER GROUND.
