DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE HONOLULU HI
126 PM HST FRI MAY 6 2016

...DROUGHT REMAINS IN PLACE OVER LEEWARD AREAS BUT EASES OVER THE
WINDWARD SLOPES...

SYNOPSIS...

ABUNDANT RAINFALL PRODUCED BY PERSISTENT TRADE WINDS HELPED EASE
DROUGHT CONDITIONS ALONG THE WINDWARD SLOPES OF THE STATE OF
HAWAII IN APRIL. HOWEVER...MOST OF THE LEEWARD AREAS DID NOT
RECEIVE MUCH OF THIS RAINFALL AND DROUGHT REMAINS FIRMLY
ENTRENCHED. THE WORST AREAS ARE ON THE BIG ISLAND WHICH HAS
EXTREME DROUGHT...OR THE D3 CATEGORY ON THE U.S. DROUGHT MONITOR
MAP...ALONG THE LOWER ELEVATIONS OF THE KAU DISTRICT FROM PAHALA
TO SOUTH POINT...AND ALONG THE KONA SLOPES FROM HUALALAI TO
MILOLII. OUTSIDE OF THE EXTREME DROUGHT AREAS IS A LARGE SECTION
OF SEVERE DROUGHT...OR THE D2 CATEGORY...WHICH ENCOMPASSES LEEWARD
KOHALA...POHAKULOA...MOST OF MAUNA LOA AND THE LEEWARD SLOPES OF
KILAUEA VOLCANO. SEVERE DROUGHT ALSO CONTINUES TO AFFECT LEEWARD
LANAI...NIIHAU...SOUTH KAUAI AND THE SOUTHWEST SLOPE OF HALEAKALA
FROM THE KIHEI-MAKENA COASTLINE UP TO THE KULA HIGHWAY. MODERATE
DROUGHT...OR THE D1 CATEGORY...PERSISTS OVER THE LEEWARD AREAS OF
MOLOKAI...OAHU AND THE WEST MAUI MOUNTAINS.

THE U.S. DEPARTMENT OF AGRICULTURE DECLARED HAWAII COUNTY AND MAUI
COUNTY TO BE PRIMARY NATURAL DISASTER AREAS ON APRIL 13 AND APRIL
20...RESPECTIVELY...DUE TO THE STRENGTH AND PERSISTENCE OF THE
DROUGHT.

SUMMARY OF IMPACTS...

KAUAI.
A LATE MARCH HEAVY RAIN EVENT HELPED STABILIZE LEEWARD DROUGHT CONDITIONS
TEMPORARILY BUT FIELD REPORTS INDICATE THAT SOIL MOISTURE REMAINS
LOW. THE LACK OF FOLLOW-ON RAINFALL MEANS THAT RECENT PASTURE
REGROWTH MAY BE SHORT-LIVED.

OAHU.
VEGETATION CONDITIONS HAVE IMPROVED OVER THE WINDWARD AND INTERIOR LEEWARD
SLOPES OF THE KOOLAU MOUNTAINS. HOWEVER...VEGETATION ALONG THE
LEEWARD SLOPES OF THE WAIANAE RANGE REMAIN DRY AND BRUSH FIRES ARE
A SIGNIFICANT CONCERN HEADING INTO THE DRY SEASON.

MOLOKAI AND LANAI.
NO SIGNIFICANT CHANGES SINCE THE PREVIOUS REPORT. PASTURE AND
GENERAL VEGETATION CONDITIONS IN WESTERN MOLOKAI AND LANAI ARE
POOR BASED ON SATELLITE-BASED VEGETATION HEALTH DATA.

MAUI.
THE MAUI COUNTY DEPARTMENT OF WATER SUPPLY HAS AN ONGOING REQUEST
FOR A VOLUNTARY 10 PERCENT REDUCTION IN WATER USE FOR UPCOUNTRY
MAUI CUSTOMERS. BRUSH FIRES ALSO REMAIN A TREMENDOUS CONCERN FOR
THE LEEWARD AREAS...ESPECIALLY SINCE STATE FORESTRY OFFICIALS
INDICATED THAT FIRE SUPPRESSION FUNDS FOR 2016 HAVE BEEN ALREADY
BEEN EXHAUSTED.

BIG ISLAND.
AMPLE TRADE WIND RAINFALL HAS HELPED FILL WATER CATCHMENT TANKS
ALONG THE WINDWARD SLOPES. HOWEVER...MOST OF THE LEEWARD AREAS
REMAIN DRY AND DROUGHT IMPACT REPORTS CONTINUE TO ARRIVE. GROWERS
OF COFFEE AND OTHER TROPICAL FRUITS OPERATING ON THE KONA SLOPES
REPORTED REDUCED PRODUCTION. ONE FARMER MENTIONED THAT THE ONGOING
DROUGHT IS WORSE THAN IN 2010 AND WAS EXPECTING A VERY SMALL
COFFEE CROP. WITHIN THE EXTREME DROUGHT AREA NEAR SOUTH POINT...A
RANCHER ESTIMATED THAT THERE IS ONLY ONE OR TWO MONTHS OF DRY FEED
LEFT HEADING INTO THE DRY SEASON. SIMILAR TO MAUI...BRUSH FIRES ARE
A SIGNIFICANT CONCERN ON THE LEEWARD AREAS OF THE BIG ISLAND...AS
HIGHLIGHTED BY A RECENT FIRE NEAR KAILUA-KONA.

NOT ALL OF THE DROUGHT IMPACTS ARE CONSIDERED TO BE BAD. COUNTY
OFFICIALS GAVE PARTIAL CREDIT TO THE DRY CONDITIONS FOR HELPING
BRING THE RECENT DENGUE FEVER OUTBREAK UNDER CONTROL BY CREATING
LESS FAVORABLE MOSQUITO BREEDING CONDITIONS.

CLIMATE SUMMARY...
ACCORDING TO THE NOAA CLIMATE PREDICTION CENTER...EL NINO IS WEAKENING
IN THE PACIFIC OCEAN. EL NINO WILL LIKELY TRANSITION TO ENSO-
NEUTRAL CONDITIONS DURING THE LATE SPRING OR EARLY SUMMER OF
2016...WITH A POSSIBLE TRANSITION TO LA NINA CONDITIONS IN THE
SECOND HALF OF THE YEAR.

PRECIPITATION/TEMPERATURE OUTLOOK...
THE LONG-LEAD HAWAIIAN ISLANDS OUTLOOK ISSUED ON APRIL 21 BY THE
NOAA CLIMATE PREDICTION CENTER INDICATED THAT PROBABILITIES DO
NOT FAVOR ABOVE OR BELOW MEDIAN PRECIPITATION THROUGH THE SUMMER.
TEMPERATURE PROBABILITIES FAVOR ABOVE AVERAGE CONDITIONS INTO THE
FALL SEASON. THE NEXT LONG-LEAD OUTLOOK WILL BE ISSUED BY THE
CLIMATE PREDICTION CENTER ON MAY 19.

HYDROLOGIC SUMMARY AND OUTLOOK...
DATA FROM THE U.S. GEOLOGICAL SURVEY INDICATED THAT MOST OF THE MONITORED
STREAMS ACROSS THE STATE HAD 30-DAY FLOW LEVELS IN THE NEAR TO
BELOW NORMAL RANGE. AVERAGE FLOW LEVELS ARE EXPECTED TO REMAIN IN
THE NORMAL TO BELOW NORMAL RANGE THROUGH THE SUMMER BASED ON THE
PRECIPITATION OUTLOOK.

NEXT ISSUANCE DATE...
THE NEXT DROUGHT INFORMATION STATEMENT WILL BE ISSUED ON JUNE 10
2016 OR SOONER IF NECESSARY IN RESPONSE TO SIGNIFICANT CHANGES IN
CONDITIONS.
