DROUGHT INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE HONOLULU HI  
855 AM HST THU JAN 18 2018  
   
..SEVERE DROUGHT NO LONGER PRESENT IN HAWAII
 
 
SYNOPSIS...  
 
A RECENT ASSESSMENT INDICATED THAT SEVERE DROUGHT, OR THE D2  
CATEGORY ON THE U.S. DROUGHT MONITOR MAP, IS NO LONGER PRESENT  
OVER THE LOWER SLOPES OF THE SOUTH KOHALA DISTRICT ON THE BIG  
ISLAND. THE AREA IS NOW CONSIDERED TO BE UNDER MODERATE DROUGHT  
CONDITIONS, OR THE D1 CATEGORY. MODERATE DROUGHT ALSO EXISTS OVER  
THE UPPER SLOPES OF THE SOUTH KOHALA DISTRICT, THE SOUTHERN  
PORTION OF THE KAU DISTRICT, AND THE LOWER LEEWARD SLOPES OF  
KAUAI. THERE ARE NO OTHER AREAS CONSIDERED TO BE IN DROUGHT ACROSS  
THE MAIN HAWAIIAN ISLANDS.  
 
SUMMARY OF IMPACTS...  
 
KAUAI.  
A RANCHER OPERATING ALONG THE LOWER SOUTHERN SLOPES REPORTED  
DEGRADED PASTURES THAT ARE NOT ABLE TO FULLY SUPPORT GRAZING.  
 
OAHU.  
THERE ARE NO DROUGHT IMPACTS TO REPORT.  
 
MAUI COUNTY  
THERE ARE NO DROUGHT IMPACTS TO REPORT.  
 
BIG ISLAND.  
OVERALL, PASTURE CONDITIONS HAVE CONTINUED TO IMPROVE OVER THE  
PAST MONTH WITHIN THE EXISTING DROUGHT DEPICTION AREAS. FOR THE  
REST OF THE ISLAND THERE HAVE BEEN NO REPORTS OF DROUGHT RELATED  
IMPACTS. HOWEVER, RAINFALL DATA INDICATED THAT DRIER THAN AVERAGE  
CONDITIONS HAVE RECENTLY SPREAD FROM THE KAU DISTRICT INTO THE  
VOLCANO AND GLENWOOD AREAS OF UPPER PUNA SO DROUGHT-RELATED  
IMPACTS MAY BEGIN TO OCCUR IF MORE SEASONAL RAINS DON'T RESUME  
SOON.  
 
CLIMATE SUMMARY...  
ACCORDING TO THE NOAA CLIMATE PREDICTION CENTER, LA NINA  
CONDITIONS ARE PRESENT IN THE PACIFIC OCEAN. THIS LA NINA EVENT  
IS FORECAST TO TRANSITION TO ENSO-NEUTRAL CONDITIONS IN MID- TO  
LATE-SPRING 2018.  
 
PRECIPITATION/TEMPERATURE OUTLOOK...  
THE LONG-LEAD HAWAIIAN ISLANDS OUTLOOK ISSUED ON JANUARY 18 BY THE NOAA  
CLIMATE PREDICTION CENTER SHOWS PROBABILITIES FAVORING ABOVE  
NORMAL RAINFALL INTO THE MIDDLE OF SPRING. THE ENHANCED RAINFALL  
MAY PRIMARILY AFFECT THE NORTH- AND EAST-FACING SLOPES WITH THE  
POTENTIAL FOR THE SOUTH- AND WEST-FACING SLOPES TO BE DRIER THAN  
NORMAL. PROBABILITIES FAVOR ABOVE NORMAL TEMPERATURES ACROSS THE  
ENTIRE STATE INTO SUMMER 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 FEBRUARY 15.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
DATA FROM THE U.S. GEOLOGICAL SURVEY INDICATED THAT MOST OF THE  
MONITORED STREAMS ON KAUAI HAD DECEMBER FLOW LEVELS IN THE BELOW  
NORMAL RANGE. MOST OF THE MONITORED STREAMS ON OAHU AND THE BIG  
ISLAND HAD NORMAL FLOW LEVELS. MAUI COUNTY FLOW LEVELS WERE MOSTLY  
ABOVE NORMAL. BASED ON THE PRECIPITATION OUTLOOK, STREAMS AND  
RIVERS DRAINING THE NORTH- AND EAST-FACING SLOPES OF THE HAWAIIAN  
ISLANDS HAVE THE HIGHEST PROBABILITIES FOR STREAMFLOW IN THE NEAR  
TO ABOVE NORMAL RANGE THROUGH THE WINTER MONTHS.  
 
NEXT ISSUANCE DATE...  
THIS WILL BE THE FINAL DROUGHT INFORMATION STATEMENT UNTIL SEVERE  
DROUGHT RETURNS TO THE MAIN HAWAIIAN ISLANDS.
