..DROUGHT WORSENS ON THE BIG ISLAND AND LEEWARD MAUI
 
 
SYNOPSIS...  
CONTINUED DRYNESS DURING JANUARY, ESPECIALLY OVER THE LEEWARD  
SECTIONS OF THE BIG ISLAND, RESULTED IN AN EXPANSION OF SEVERE  
DROUGHT, OR THE D2 CATEGORY ON THE U.S. DROUGHT MONITOR MAP. THE  
SEVERE DROUGHT AREA OVER THE SOUTH KOHALA DISTRICT OF THE BIG  
ISLAND SPREAD FARTHER UPSLOPE INTO THE WAIKII AREA. MODERATE  
DROUGHT, OR THE D1 CATEGORY, SPREAD EASTWARD TO COVER ALL OF THE  
KAU, PUNA, SOUTH HILO, AND NORTH HILO DISTRICTS, AND NORTHWARD AS  
FAR AS OOKALA IN THE HAMAKUA DISTRICT.  
 
SEVERE DROUGHT WAS ALSO DESIGNATED FOR THE LOWER LEEWARD SLOPE OF  
HALEAKALA FROM KIHEI TO WAILEA. MODERATE DROUGHT ON MAUI WAS ALSO  
SPREADING INTO THE WINDWARD AREAS BUT WAS PUSHED BACK INTO THE  
LOWER LEEWARD SECTIONS OF HALEAKALA AND THE WEST MAUI MOUNTAINS BY  
WET WINDWARD AND CENTRAL VALLEY CONDITIONS IN LATE JANUARY.  
 
ELSEWHERE ACROSS THE STATE, MODERATE DROUGHT IN LEEWARD KAUAI  
SPREAD SOUTHEASTWARD TO KOLOA, BUT REDUCED IN SIZE IN LEEWARD OAHU  
AND MOLOKAI.  
 
SUMMARY OF IMPACTS...  
KAUAI AND OAHU.  
NO SIGNIFICANT CHANGES SINCE THE LAST REPORT. LEEWARD AREAS OF  
BOTH ISLANDS HAD DETERIORATING VEGETATION CONDITIONS. HOWEVER, NO  
SIGNIFICANT AGRICULTURAL IMPACTS HAVE YET BEEN REPORTED.  
 
MAUI COUNTY.  
PASTURES CONDITIONS ARE POOR OVER THE LOWER LEEWARD SLOPES OF  
HALEAKALA FROM KIHEI TO WAILEA. WET CONDITIONS DURING LATE  
JANUARY EASED DROUGHT IN MAUI'S CENTRAL VALLEY FROM WAILUKU TO  
MAALAEA.  
 
BIG ISLAND.  
DROUGHT IMPACTS HAVE BEEN INCREASING OVER THE PAST  
SEVERAL WEEKS. THE MAJORITY OF THE IMPACTS HAVE BEEN TO RANCHING  
OPERATIONS. THESE INCLUDE VERY POOR PASTURE CONDITIONS WHICH HAVE  
BEEN RESULTING IN REDUCED CATTLE GROWTH. SOME RANCHERS HAVE ALSO  
BEEN FORCED TO REDUCE HERD SIZES. SEVERAL RANCHERS REPORTED HAVING  
TO HAUL WATER FOR CATTLE DUE TO WATER HOLES DRYING UP, AND HAVE  
BEEN PROVIDING SUPPLEMENTAL FEED, WHICH INCREASES OPERATING  
COSTS. AN AQUACULTURE OPERATION IN UPPER HILO REPORTED HAVING TO  
PROVIDE AERATION FOR THEIR FISH DUE TO INADEQUATE SURFACE WATER  
AND SPRING FLOWS.  
 
CLIMATE SUMMARY...  
ACCORDING TO THE NOAA CLIMATE PREDICTION CENTER (CPC), ENSO-  
NEUTRAL CONDITIONS ARE STILL PRESENT IN THE PACIFIC OCEAN. THE  
FORECAST FROM CPC CONTINUES TO FAVOR A TRANSITION TO AN EL NINO  
STATE IN EARLY 2019. THE EL NINO IS FORECAST TO BE A WEAK EVENT BY  
A CONSENSUS OF THE MAIN DYNAMICAL AND STATISTICAL MODELS.  
 
PRECIPITATION/TEMPERATURE OUTLOOK...  
THE LONG-LEAD HAWAIIAN ISLANDS OUTLOOK ISSUED ON JANUARY 17 BY THE NOAA  
CLIMATE PREDICTION CENTER SHOWS PROBABILITIES FAVORING BELOW NORMAL  
RAINFALL INTO THE SPRING MONTHS AS A RESULT OF THE DEVELOPING EL  
NINO EVENT. PROBABILITIES FAVOR ABOVE NORMAL TEMPERATURES ACROSS  
THE ENTIRE STATE INTO THE SUMMER DUE TO THE FORECAST 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 21.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
DATA FROM THE U.S. GEOLOGICAL SURVEY INDICATED THAT MOST OF THE  
MONITORED STREAMS ACROSS THE STATE HAD NEAR TO BELOW NORMAL FLOW  
LEVELS. BASED ON THE PRECIPITATION OUTLOOK, FLOW LEVELS ARE EXPECTED  
TO REMAIN NEAR TO BELOW NORMAL THROUGH SPRING 2019.  
 
NEXT ISSUANCE DATE...  
THE NEXT DROUGHT INFORMATION STATEMENT WILL BE ISSUED ON MARCH 7,  
2019 OR SOONER IF NECESSARY IN RESPONSE TO SIGNIFICANT CHANGES IN  
CONDITIONS.
