MUCH OF NOVEMBER KEPT LEEWARD AREAS MOSTLY DRY ACROSS THE STATE.
LOWER ELEVATIONS OF KAUAI FROM HANAPEPE TO WAIMEA...AND IN THE
KIHEI AREA OF MAUI HAVE DETERIORATED TO EXTREME DROUGHT...OR THE
D3 CATEGORY ON THE U.S. DROUGHT MONITOR MAP. CONDITIONS ALSO
WORSENED IN THE SOUTH KOHALA DISTRICT OF THE BIG ISLAND TO THE

MODERATE DROUGHT...OR THE D1 CATEGORY...FORMED IN THE LEEWARD
SECTIONS OF OAHU...MOLOKAI AND LANAI...AND NEAR SOUTH POINT ON THE
BIG ISLAND.

A LOW PRESSURES SYSTEM IN EARLY DECEMBER BROUGHT SOME RAINFALL TO
LEEWARD AREAS AND HELPED STABILIZE THE DROUGHT SITUATION BUT IT IS
TOO SOON TO TELL HOW MUCH IMPROVEMENT...IF ANY...OCCURRED AS A
RESULT.

SUMMARY OF IMPACTS...

KAUAI.
NON-IRRIGATED PASTURES AND GENERAL VEGETATION FROM HANAPEPE TO
WAIMEA WERE IN VERY POOR CONDITION. DRY CONDITIONS HAVE PERSISTED
LONG ENOUGH TO SIGNIFICANTLY AFFECT TREES IN THE LOWER ELEVATIONS
OF THE WAIMEA CANYON.

OAHU.
VEGETATION CONDITIONS IN THE LEEWARD AREAS OF THE WAIANAE RANGE
HAVE DETERIORATED OVER THE PAST COUPLE OF MONTHS. SIGNIFICANT
BRUSH FIRES IN THE AREA HAVE OCCURRED RECENTLY.

MOLOKAI AND LANAI.
THERE HAVE BEEN NO REPORTS OF DROUGHT IMPACTS BUT SATELLITE-BASED VEGETATION
HEALTH DATA INDICATED WORSENING CONDITIONS OVER THE PAST MONTH.

MAUI.
PASTURES OVER THE LOWER LEEWARD SLOPES OF HALEAKALA...ESPECIALLY
IN THE KAONOULU AREA OF KIHEI...WERE IN VERY POOR CONDITION.

BIG ISLAND.
PASTURES IN THE LOWER ELEVATIONS OF THE SOUTH KOHALA DISTRICT NEAR
AND UPSLOPE FROM KAWAIHAE AND PUAKO HAVE WORSENED CONSIDERABLY
OVER THE PAST COUPLE OF MONTHS. RANCHERS OPERATING IN THE SOUTH
POINT AREA ALSO REPORTED POOR PASTURE CONDITIONS THOUGH A RECENT
HEAVY RAIN EVENT MAY HAVE BROUGHT SUFFICIENT RAINFALL TO PULL THE
AREA OUT OF DROUGHT. FOLLOW-UP RAINFALL WILL BE NEEDED TO SUPPORT
SUFFICIENT PASTURE REGROWTH.

CLIMATE SUMMARY...
ACCORDING TO THE NOAA CLIMATE PREDICTION CENTER...LA NINA
CONDITIONS ARE PRESENT IN THE PACIFIC OCEAN AND ARE SLIGHTLY
FAVORED TO PERSIST THROUGH THE WINTER MONTHS.

PRECIPITATION/TEMPERATURE OUTLOOK...
THE LONG-LEAD HAWAIIAN ISLANDS OUTLOOK ISSUED ON NOVEMBER 17 BY

FAVOR ABOVE NORMAL PRECIPITATION AND TEMPERATURES THROUGH SPRING
2017. THE NEXT LONG-LEAD OUTLOOK WILL BE ISSUED BY THE CLIMATE

MONITORED STREAMS ACROSS THE STATE HAD 30-DAY FLOW LEVELS IN THE
NORMAL TO BELOW NORMAL RANGE. A FEW SITES ON OAHU HAD FLOW LEVELS
IN THE ABOVE NORMAL RANGE. AVERAGE FLOW LEVELS ARE EXPECTED TO BE
ABOVE NORMAL BASED ON THE EXPECTATION OF ABOVE NORMAL RAINFALL
OVER THE NEXT SEVERAL MONTHS.
