...SEVERE DROUGHT RETURNS TO THE BIG ISLAND...

SYNOPSIS...

An anomalously stable atmosphere has limited rainfall over many
areas of the Big Island. As a result, severe drought, or the D2
category on the U.S. Drought Monitor map, has returned quickly to
the leeward areas of the South Kohala District. Moderate drought,
or D1 category conditions, have spread eastward to cover all of
the windward slopes and the Kau District. Only portions of the
Kona slopes and the windward slopes of the Kohala Mountains remain
drought-free on the Big Island.

SUMMARY OF IMPACTS...

Kauai, Oahu, and Maui County.
No significant drought impacts reported.

Big Island.
Impact reports have been coming in more frequently over the past
month as conditions worsen. Field reports from the leeward South
Kohala District between Waimea and Kawaihae have been showing very
poor vegetation conditions. Producers operating in the area have
destocked pastures. Even the normally wetter windward areas have
been deteriorating lately. Pastures and general vegetation in the
Ookala and Paauilo areas were becoming dry and a brushfire
scorched several acres in the area on June 26. A ginger farmer
operating in the Umauma area of the North Hilo District reported
stunted growth in his plants. In the Pohoiki, Mountain View, and
Glenwood areas of the Puna District, producers have been culling
herds due to reduced forage. Puna District residents on catchment
systems have also been hauling more water for basic needs due to
insufficient rainfall.

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 fall season of 2017.
The probability of El Nino development decreases through the rest
of the year.

PRECIPITATION/TEMPERATURE OUTLOOK...
The Long-Lead Hawaiian Islands Outlook issued on June 15 by the
NOAA Climate Prediction Center does not show any tilt in the
probabilities for above or below normal rainfall through the
summer. 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 July
20.

HYDROLOGIC SUMMARY AND OUTLOOK...
Data from the U.S. Geological Survey indicated that most of the
monitored streams from Kauai to Molokai had 30-day flow levels in
the near normal to above normal range. Most of the monitored
streams on Maui and the Big Island had 30-day flow levels in the
normal to below normal range. Since probabilities do not favor
below normal rainfall, average flow on the Big Island and Maui
should return to more normal levels with the return of more
typical trade wind rainfall conditions.

NEXT ISSUANCE DATE...
The next Drought Information Statement will be issued on August
10, 2017 or sooner if necessary in response to significant changes
in conditions.
