TROPICAL STORM HONE, LOCATED ABOUT 155 MILES SOUTHEAST OF HILO AT
2 PM HST THIS AFTERNOON, IS FORECAST TO MOVE TOWARD THE WEST FOR THE
NEXT SEVERAL DAYS, WITH SOME STRENGTHENING POSSIBLE OVER THE NEXT 24
HOURS. 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.
MODERATE RAINFALL OF 1 TO 3 INCHES HAS ALREADY FALLEN ACROSS WINDWARD
BIG ISLAND, AND AS HONE MOVES CLOSER, BANDS OF HEAVY SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO INTENSIFY LATE THIS AFTERNOON AND
TONIGHT, BRINGING A THREAT OF FLASH FLOODING TO THE ENTIRE BIG ISLAND,
THOUGH THE GREATEST POTENTIAL WILL BE ACROSS THE HAMAKUA, HILO, PUNA,
AND KAU DISTRICTS. STORM TOTAL RAINFALL ESTIMATES FOR THE BIG ISLAND
THIS WEEKEND RANGE FROM 6 TO 12 INCHES WITH LOCALLY HIGHER AMOUNTS. A
FEW LINGERING THUNDERSTORMS AND HEAVY SHOWERS MAY PERSIST OVER
PORTIONS OF BIG ISLAND INTO MONDAY, ESPECIALLY 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. THESE WINDS WILL WILL CONTINUE TO INCREASE
AFTERNOON AND MAY BECOME LOCALLY DAMAGING BY NIGHTFALL. 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 THIS AFTERNOON
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.
PREPARATIONS FOR TROPICAL STORM HONE SHOULD BE COMPLETE.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
FOLLOW THE ADVICE OF LOCAL OFFICIALS.
* OTHER PREPAREDNESS INFORMATION:
ALL PREPARATIONS TO PROTECT LIFE AND PROPERTY SHOULD BE RUSHED TO
COMPLETION. ENSURE YOU ARE IN A SAFE LOCATION BEFORE THE ONSET OF
STRONG WINDS OR POSSIBLE FLOODING.
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.
WHEN SECURING YOUR PROPERTY, OUTSIDE PREPARATIONS SHOULD BE CONCLUDED
AS SOON AS POSSIBLE BEFORE CONDITIONS DETERIORATE. THE ONSET OF
STRONG GUSTY WINDS OR FLOODING CAN CAUSE CERTAIN PREPAREDNESS
ACTIVITIES TO BECOME UNSAFE.
MONITOR WEATHER.GOV, NOAA WEATHER RADIO AND LOCAL NEWS OUTLETS FOR
OFFICIAL STORM INFORMATION. LISTEN FOR POSSIBLE CHANGES TO THE
FORECAST.
