...EXTREME DROUGHT RETURNS TO THE BIG ISLAND...

SYNOPSIS...

Trade wind showers returned to the windward slopes of the Big
Island but not much rain made it to the leeward areas. As a
result, portions of the South Kohala District from Waimea to
Kawaihae, and the Kau District from Punaluu to South Point have
worsened to the extreme drought category, or the D3 level on the
U.S. Drought Monitor map. Existing severe drought, or the D2
category, persisted over 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. Dry
conditions in Maui County also pushed drought into the D2 category
along the slopes of Haleakala near Kihei and Wailea, and on the
west half of Molokai.

Drought has also developed over other areas of the state with
moderate drought, or the D1 category, forming over the lower
slopes of Kauai from Kealia to Hanapepe, and along the west side
of Lanai. Existing moderate drought over west Oahu remained in
place. Near normal trade wind rainfall over the lower sections of
the South Hilo and Puna Districts have eased drought impacts but
D1-level conditions remained in place over most of the rest of
the island not in the D2 and D3 areas.

SUMMARY OF IMPACTS...

Kauai.
Impacts have been from the agriculture sector where pastures have been
deteriorating over the past several weeks. The worst conditions
were in the areas near Poipu and Koloa.

Oahu.
Pastures and general vegetation have been drying out over west Oahu.

Maui County
Pastures and general vegetation in the Kihei area of Maui and the
Hoolehua and Maunaloa areas of Molokai were in poor condition
based on observations and reports from ranchers. 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 conservation of public water
use.

Big Island.
Reports from the Big Island over the past month showed that
pastures in portions of the South Kohala District 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 has requested 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 and are expected to
persist through the northern hemisphere`s winter season of 2017 -
2018.

PRECIPITATION/TEMPERATURE OUTLOOK...
The Long-Lead Hawaiian Islands Outlook issued on August 17 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 temperatures across the
entire state for the remainder of the year. The next long-lead
outlook will be issued by the Climate Prediction Center on
September 21.

HYDROLOGIC SUMMARY AND OUTLOOK...
Data from the U.S. Geological Survey indicated that most of the
monitored streams across the state had August flow levels in the
near normal to below normal range. A few of the streams on Kauai
and Oahu had above normal flow levels. There does not appear to be
any compelling reason to expect a change from near to below normal
streamflow through early fall.

NEXT ISSUANCE DATE...
The next Drought Information Statement will be issued on October
12, 2017 or sooner if necessary in response to significant changes
in conditions.
