NATIONAL WEATHER SERVICE HONOLULU HI
137 PM HST FRI JUN 10 2016

...MAY RAINFALL EASES DROUGHT IN PORTIONS OF THE STATE...

SYNOPSIS...

ABOVE AVERAGE RAINFALL DURING MAY...WHICH AFFECTED EVEN THE
LEEWARD PORTIONS OF THE STATE...HAS HELPED EASE DROUGHT
CONDITIONS. COMPARED TO A MONTH AGO...DROUGHT COVERAGE HAS BEEN
REDUCED FROM 60 PERCENT TO 46 PERCENT OVER THE MAIN HAWAIIAN
ISLANDS IN THE U.S. DROUGHT MONITOR MAP. THE WORST CONDITIONS WERE
ON THE BIG ISLAND WHERE AN AREA OF EXTREME DROUGHT...OR THE D3
CATEGORY ON THE U.S. DROUGHT MONITOR MAP...PERSISTS ALONG THE
LEEWARD SLOPES. THIS AREA HAS BEEN EVOLVING OVER THE PAST MONTH
WITH THE D3 COVERAGE EASING ON THE LOWER KONA SLOPES BUT SPREADING
INTO THE POHAKULOA REGION OF THE HAMAKUA DISTRICT. OVER THE REST
OF THE BIG ISLAND...SEVERE DROUGHT...OR THE D2 CATEGORY...HAS BEEN
PUSHED OUT OF THE PUNA DISTRICT AND THE UPPER LEEWARD SLOPES OF
THE KOHALA MOUNTAINS BY THE RECENT RAINFALL. SEVERE DROUGHT HAS
ALSO EASED TO MODERATE DROUGHT...OR THE D1 CATEGORY...IN SOUTH
KAUAI...NIIHAU...AND THE WEST HALF OF LANAI.

ON OAHU...MODERATE DROUGHT HAS RETREATED OFF OF THE KOOLAU RANGE
AND THE NORTHERN PORTION OF THE WAIANAE RANGE BUT PERSISTS IN THE
LOWER ELEVATIONS OF THE LEEWARD WAIANAE SLOPES. MODERATE DROUGHT
COVERAGE HAS ALSO BEEN REMOVED FROM THE SOUTHEAST-FACING SLOPES OF
HALEAKALA ON THE ISLAND OF MAUI. UNFORTUNATELY...THE KIHEI AND
WAILEA AREA OF MAUI DID NOT RECEIVE MUCH RAINFALL IN MAY AND
REMAINS LOCKED IN SEVERE DROUGHT CONDITIONS.

SUMMARY OF IMPACTS...

KAUAI.
MAY RAINFALL HELPED IMPROVE PASTURE CONDITIONS ALONG THE SOUTHERN SLOPES
OF THE ISLAND BUT MORE RAINFALL IS NEEDED FOR A FULL RECOVERY.

OAHU.
VEGETATION CONDITIONS CONTINUED TO IMPROVE DURING MAY BUT REMAIN
STRESSED IN THE LOWER ELEVATIONS OF THE WAIANAE AREA.

MOLOKAI AND LANAI.
SATELLITE-BASED VEGETATION HEALTH DATA INDICATED THAT CONDITIONS
OVER WESTERN LANAI HAVE IMPROVED OVER THE PAST MONTH. VEGETATION
HEALTH IN WEST MOLOKAI HAS IMPROVED RECENTLY BUT THE CHANGES HAVE
BEEN SPOTTY AND THE AREA APPEARS TO STILL BE UNDER STRESS.

MAUI.
CONDITIONS HAVE IMPROVED OVER THE KAUPO AND KEPUNI AREAS BUT
REMAIN DEGRADED OVER THE LOWER ELEVATIONS OF SOUTH MAUI NEAR KIHEI
AND WAILEA. THE MAUI COUNTY DEPARTMENT OF WATER SUPPLY HAS AN
ONGOING REQUEST FOR A VOLUNTARY 10 PERCENT REDUCTION IN WATER USE
FOR UPCOUNTRY MAUI CUSTOMERS.

BIG ISLAND.
ABOVE AVERAGE RAINFALL OVER THE LEEWARD SLOPES HAS IMPROVED
PASTURE AND ORCHARD CONDITIONS. REPORTS FROM COFFEE GROWERS ON THE
KONA SLOPES INDICATED THAT THE CROP FOR THIS YEAR...WHICH WAS AT
SIGNIFICANT RISK OF BEING POOR...APPEARS TO HAVE RECOVERED. FRUIT
GROWERS IN THE LOWER ELEVATIONS OF THE KONA SLOPES ALSO INDICATED
IMPROVED GROWING CONDITIONS. PASTURES HAVE BEEN RECOVERING ALONG
THE KOHALA SLOPES AND THE WAIMEA AREA WITH RANCHERS INDICATING
ADEQUATE FORAGE AND WATER.

CLIMATE SUMMARY...
ACCORDING TO THE NOAA CLIMATE PREDICTION CENTER...EL NINO HAS
DISSIPATED AND ENSO-NEUTRAL CONDITIONS ARE NOW IN PLACE IN THE
PACIFIC OCEAN. LA NINA IS EXPECTED TO DEVELOP BY THE FALL OF 2016.

PRECIPITATION/TEMPERATURE OUTLOOK...
THE LONG-LEAD HAWAIIAN ISLANDS OUTLOOK ISSUED ON MAY 19 BY THE
NOAA CLIMATE PREDICTION CENTER INDICATED THAT PROBABILITIES FAVOR
ABOVE MEDIAN PRECIPITATION DURING THE LATE SUMMER AND EARLY FALL.
THIS PROJECTION IS EXPECTED TO MAINLY AFFECT WINDWARD LOCATIONS
AND THE KONA SLOPES...WITH OTHER LEEWARD AREAS REMAINING DRY.
TEMPERATURE PROBABILITIES FAVOR ABOVE AVERAGE CONDITIONS INTO THE
FALL SEASON. THE NEXT LONG-LEAD OUTLOOK WILL BE ISSUED BY THE
CLIMATE PREDICTION CENTER ON JUNE 16.

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