DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE HONOLULU HI
1234 PM HST FRI AUG 5 2016

...DARBY SOAKS PORTIONS OF THE STATE...

SYNOPSIS...

TROPICAL STORM DARBY MADE A DIRECT IMPACT ON THE BIG ISLAND ON
JULY 23 THEN MOVED NORTHWESTWARD AND PASSED THROUGH THE KAUAI
CHANNEL ON JULY 24. FLASH FLOODING OCCURRED IN LOCALIZED AREAS OF
THE BIG ISLAND AND MAUI...AND IN SEVERAL AREAS ON THE EAST HALF
OF OAHU. SOME OF THE RAINFALL FROM DARBY FELL OVER EXISTING
DROUGHT AREAS AND PROVIDED SOME RELIEF. THIS INCLUDES THE AREA OF EXTREME
DROUGHT...OR THE D3 CATEGORY ON THE U.S. DROUGHT MONITOR
MAP...NEAR SOUTH POINT ON THE BIG ISLAND...WHICH IMPROVED TO
SEVERE DROUGHT...OR THE D2 CATEGORY. SIGNIFICANT RAINFALL OVER
MAUI COUNTY FROM DARBY DID NOT AFFECT THE EXISTING SEVERE DROUGHT
COVERAGE IN THE KIHEI...WAILEA AND MAALAEA AREAS...BUT IT DID
HELP ELIMINATE DROUGHT OVER PORTIONS OF WEST MOLOKAI.

ELSEWHERE...EXTREME DROUGHT IN THE POHAKULOA AREA OF THE BIG
ISLAND WAS UPGRADED GRADUALLY TO D1...OR MODERATE DROUGHT...DURING
JULY DUE TO THE WETTER THAN NORMAL SPRING. MODERATE DROUGHT ON
KAUAI HAS REDUCED IN SIZE BUT STUBBORNLY HANGS ON IN THE HANAPEPE
AND WAIMEA AREAS. THE SMALL SECTION OF MODERATE DROUGHT NEAR
NANAKULI IN WEST OAHU WAS ELIMINATED IN EARLY AUGUST.

SUMMARY OF IMPACTS...

KAUAI.
MOST AREAS OF KAUAI APPEAR TO BE FINE BUT LOCAL REPORTS INDICATED
THAT VEGETATION IN THE HANAPEPE AND WAIMEA AREAS ARE DRY AND IN
NEED OF RAINFALL.

OAHU.
THERE ARE NO DROUGHT IMPACTS TO REPORT.

MOLOKAI AND LANAI.
OBSERVATIONS FROM THE USDA AND NOAA INDICATED THAT VEGETATION
CONDITIONS HAVE IMPROVED OVER PORTIONS OF WEST MOLOKAI BUT REMAIN
DRY OVER THE SOUTHERN SLOPES FROM HALE O LONO EASTWARD TO KAWELA.

MAUI.
RANCHERS INDICATED THAT RAINFALL FROM TROPICAL STORM DARBY DID NOT PROVIDE
MUCH RELIEF FOR THE LEEWARD SLOPES OF HALEAKALA CURRENTLY UNDER
DROUGHT CONDITIONS.

BIG ISLAND.
PASTURES AND GENERAL VEGETATION CONDITIONS HAVE BEEN IMPROVING
OVER THE PAST MONTH IN MOST AREAS. TROPICAL STORM DARBY BROUGHT
MUCH NEEDED RAINFALL TO THE SOUTHERN PORTION OF THE KAU DISTRICT
BUT FOLLOW-UP RAINFALL IS NEEDED TO CONTINUE THE IMPROVEMENT
TREND. VERY LITTLE RAINFALL HAS OCCURRED OVER THE EXISTING DROUGHT
AREA NEAR SOUTH POINT SINCE DARBY MOVED THROUGH SO CONTINUED
RECOVERY IS NOT YET ASSURED.

CLIMATE SUMMARY...
ACCORDING TO THE NOAA CLIMATE PREDICTION CENTER...ENSO-NEUTRAL CONDITIONS
ARE PRESENT IN THE PACIFIC OCEAN. LA NINA IS STILL FAVORED TO
DEVELOP IN LATE SUMMER OR EARLY FALL OF 2016 BUT THE PROBABILITIES
OF THIS OCCURRING HAVE BEEN REDUCED IN RECENT WEEKS.

PRECIPITATION/TEMPERATURE OUTLOOK...
THE LONG-LEAD HAWAIIAN ISLANDS OUTLOOK ISSUED ON JULY 21 BY THE
NOAA CLIMATE PREDICTION CENTER SHOWED THAT PROBABILITIES FAVOR
ABOVE MEDIAN PRECIPITATION DURING THE LATE SUMMER AND EARLY FALL
FOR WINDWARD LOCATIONS BUT BELOW MEDIAN PRECIPITATION FOR LEEWARD
SITES. TEMPERATURE PROBABILITIES FAVOR ABOVE AVERAGE CONDITIONS
INTO THE FALL AND WINTER SEASONS. THE NEXT LONG-LEAD OUTLOOK WILL
BE ISSUED BY THE CLIMATE PREDICTION CENTER ON AUGUST 18.

HYDROLOGIC SUMMARY AND OUTLOOK...
DATA FROM THE U.S. GEOLOGICAL SURVEY INDICATED THAT ALL OF THE
MONITORED STREAMS ACROSS THE STATE HAD 30-DAY FLOW LEVELS IN THE
NORMAL TO HIGH RANGE. AVERAGE FLOW LEVELS ARE EXPECTED TO BE IN
THE NORMAL TO ABOVE NORMAL RANGE THROUGH THE FALL.

NEXT ISSUANCE DATE...
THE NEXT DROUGHT INFORMATION STATEMENT WILL BE ISSUED ON SEPTEMBER 8
2016 OR SOONER IF NECESSARY IN RESPONSE TO SIGNIFICANT CHANGES IN
CONDITIONS.
