Drought Information Statement

...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.
