..SEVERE DROUGHT RETURNS TO SOUTH KAUAI
 
 
SYNOPSIS...  
 
DRY CONDITIONS CONTINUED TO AFFECT MANY AREAS OF THE STATE DURING  
SEPTEMBER. DROUGHT CONDITIONS WORSENED ON KAUAI WITH THE RETURN OF  
SEVERE DROUGHT, OR THE D2 CATEGORY ON THE U.S. DROUGHT MONITOR  
MAP, TO THE SOUTHERN SLOPES OF THE ISLAND FROM HANAPEPE TO KEKAHA.  
MODERATE DROUGHT, OR THE D1 CATEGORY, SPREAD INTO THE NORMALLY WET  
WINDWARD SLOPES OF THE KOHALA MOUNTAINS ON THE BIG ISLAND. EXTREME  
DROUGHT, WHICH IS THE D3 CATEGORY, MAINTAINED ITS BIG ISLAND  
PRESENCE IN THE SOUTH KOHALA DISTRICT FROM WAIMEA TO KAWAIHAE AND  
THE KAU DISTRICT FROM PUNALUU TO SOUTH POINT. SEVERE DROUGHT ALSO  
CONTINUED ALONG THE UPPER SLOPES OF THE HAMAKUA, NORTH HILO, AND  
SOUTH HILO DISTRICTS, AND ALONG THE SLOPES OF THE KAU DISTRICT  
FROM PAHALA TO HAWAIIAN OCEAN VIEW ESTATES.  
 
IN MAUI COUNTY, SEVERE DROUGHT CONTINUED ALONG THE LOWER SLOPES OF  
HALEAKALA NEAR KIHEI AND WAILEA, AND ON THE WEST HALF OF MOLOKAI.  
MODERATE DROUGHT REMAINED IN PLACE OVER THE REST OF HALEAKALA AND  
OVER THE LEEWARD SLOPES OF THE WEST MAUI MOUNTAINS. ON OAHU,  
MODERATE DROUGHT CONTINUED OVER THE LEEWARD SECTIONS OF THE  
WAIANAE RANGE.  
 
SUMMARY OF IMPACTS...  
 
KAUAI.  
NON-IRRIGATED PASTURES CONTINUED TO DETERIORATE OVER THE LOWER  
SLOPES OF SOUTH KAUAI, ESPECIALLY IN THE AREA FROM HANAPEPE TO  
KEKAHA. ALTHOUGH STILL DRIER THAN NORMAL, PASTURES IN SOUTHEAST  
AND EAST KAUAI HAVE HAD BOUTS OF RAIN THAT PREVENTED DROUGHT  
CONDITIONS FROM WORSENING.  
 
OAHU.  
PASTURES AND GENERAL VEGETATION REMAIN DRY OVER WEST OAHU. BRUSH  
FIRES HAVE BEEN INCREASING IN FREQUENCY IN RECENT WEEKS.  
 
MAUI COUNTY  
NO SIGNIFICANT CHANGES SINCE THE PREVIOUS REPORT. PASTURES AND  
GENERAL VEGETATION IN THE KIHEI AREA OF MAUI AND THE HOOLEHUA AND  
MAUNALOA AREAS OF MOLOKAI REMAIN IN POOR CONDITION. IN THE  
UPCOUNTRY AREA, A STAGE 1 WATER SHORTAGE DECLARED ON JULY 18 BY  
THE DEPARTMENT OF WATER SUPPLY REMAINED IN EFFECT DUE TO REDUCED  
INCOMING SUPPLY LEVELS AND THE ONGOING DRY WEATHER CONDITIONS. THE  
DECLARATION ASKS FOR A VOLUNTARY REDUCTION OF PUBLIC WATER USE.  
 
BIG ISLAND.  
A FARMER OPERATING IN WAIPIO VALLEY REPORTED THAT LOW STREAM FLOW  
CONDITIONS HAVE IMPACTED TARO PRODUCTION AND STUNTED PLANT  
GROWTH. PASTURES IN PORTIONS OF THE SOUTH KOHALA DISTRICT AND THE  
KAU DISTRICT NEAR SOUTH POINT WERE DEPLETED. PASTURES AND GENERAL  
VEGETATION FROM PUNALUU TO HAWAIIAN OCEAN VIEW ESTATES IN THE KAU  
DISTRICT WERE REPORTED TO BE IN VERY POOR CONDITION. FROM THE  
PUBLIC WATER SECTOR, THE COUNTY OF HAWAII DEPARTMENT OF WATER  
SUPPLY MAINTAINED ITS REQUEST FOR A 10 PERCENT VOLUNTARY REDUCTION  
IN WATER USE FOR THE NINOLE AND HAKALAU AREAS OF THE HAMAKUA  
COAST. WATER SUPPLY SPRINGS IN THE AREA WERE REPORTED TO BE  
RUNNING LOW.  
 
CLIMATE SUMMARY...  
ACCORDING TO THE NOAA CLIMATE PREDICTION CENTER, ENSO-NEUTRAL  
CONDITIONS ARE PRESENT IN THE PACIFIC OCEAN BUT THE ATMOSPHERE  
AND OCEAN ARE TRENDING TOWARD A LA NINA STATE. THUS, A LA NINA  
WATCH REMAINS IN EFFECT AND LA NINA CONDITIONS ARE EXPECTED TO  
DEVELOP DURING THE FALL AND PERSIST THROUGH THE NORTHERN  
HEMISPHERE'S WINTER SEASON OF 2017 - 2018.  
 
PRECIPITATION/TEMPERATURE OUTLOOK...  
THE LONG-LEAD HAWAIIAN ISLANDS OUTLOOK ISSUED ON SEPTEMBER 21 BY  
THE NOAA CLIMATE PREDICTION CENTER DOES NOT SHOW ANY TILT IN THE  
PROBABILITIES FOR ABOVE OR BELOW NORMAL RAINFALL THROUGH THE FALL.  
PROBABILITIES FAVOR ABOVE NORMAL RAINFALL FOR THE WINTER. IF LA  
NINA DEVELOPS, THE ENHANCED RAINFALL MAY PRIMARILY AFFECT THE  
NORTH- AND EAST-FACING SLOPES LEAVING THE SOUTH- AND WEST-FACING  
SLOPES DRIER THAN NORMAL. PROBABILITIES FAVOR ABOVE NORMAL  
TEMPERATURES ACROSS THE ENTIRE STATE FOR THE REMAINDER OF THE YEAR  
AND INTO SPRING 2018 DUE TO THE FORECASTED PERSISTENCE OF ABOVE  
AVERAGE SEA SURFACE TEMPERATURES AROUND THE HAWAIIAN ISLANDS. THE  
NEXT LONG-LEAD OUTLOOK WILL BE ISSUED BY THE CLIMATE PREDICTION  
CENTER ON OCTOBER 19.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
DATA FROM THE U.S. GEOLOGICAL SURVEY INDICATED THAT MOST OF THE  
MONITORED STREAMS ACROSS THE STATE HAD SEPTEMBER FLOW LEVELS IN  
THE BELOW NORMAL RANGE. A FEW OF THE STREAMS ON KAUAI AND OAHU HAD  
NEAR TO ABOVE NORMAL FLOW LEVELS. THE PERSISTENCE OF DRY  
CONDITIONS OVER MUCH OF THE STATE WILL REQUIRE SUSTAINED PERIODS  
OF ENHANCED RAINFALL TO RETURN BASE FLOW CONDITIONS TO A MORE  
NORMAL STATE.  
 
NEXT ISSUANCE DATE...  
THE NEXT DROUGHT INFORMATION STATEMENT WILL BE ISSUED ON NOVEMBER  
9, 2017 OR SOONER IF NECESSARY IN RESPONSE TO SIGNIFICANT CHANGES  
IN CONDITIONS.
