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

SYNOPSIS...

Weather systems brought significant rainfall to portions of the
state from Kauai to Maui but for the most part weakened
considerably before reaching the Big Island. This has resulted in
increasing rainfall deficits since the start of the new year and
the onset of drought conditions during what should be the wet
season. Below average rainfall has been occurring across most of
the Big Island but the worst rainfall deficits were along the
leeward slopes with drought impacts primarily coming from the
agriculture sector.

Moderate drought, or the D1 category on the U.S. Drought Monitor
map, initiated in a small area of the South Kohala District of the
Big Island during mid-January 2017. Moderate drought coverage
spread to include the southwestern half of the island by mid-
March. With the ongoing dryness, rainfall deficits and drought
impacts have reached levels consistent with severe drought, or D2
category conditions, in the area west of a line from approximately
Kawaihae to Naalehu.

SUMMARY OF IMPACTS...

Kauai.
No significant drought impacts reported.

Oahu.
No significant drought impacts reported.

Molokai and Lanai.
No significant drought impacts reported.

Maui.
Low intake ditch flows supplying the Upcountry Maui water system
have resulted in decreasing reservoir levels. As a result, the
Maui County Department of Water Supply has declared that effective
April 9 a Stage I water shortage will be in effect which calls
for a voluntary reduction in water use.

Big Island.
Ranchers have been reporting poor pasture conditions and some have
been forced to destock grazing areas. Coffee farmers indicated
that flowering has occurred but a continued lack of rain will
result in lower production. A protea grower in the Kau District
reported some plant loss and reduced production.

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 spring 2017. There is an
increasing chance for El Nino development into fall 2017.

Precipitation/temperature outlook...
The Long-Lead Hawaiian Islands Outlook issued on March 16 by the
NOAA Climate Prediction Center showed that probabilities favor
below normal precipitation and above normal temperatures through
spring 2017 for the east half of the state. For the west half of
the state, probabilities are tilted toward above normal
temperatures through the spring but do not favor above or below
normal precipitation. The next long-lead outlook will be issued
by the Climate Prediction Center on April 20.

Hydrologic summary and outlook...
Data from the U.S. Geological Survey indicated that most of the
monitored streams on Kauai and Oahu had 30-day flow levels in the
near normal range. Most of the monitored streams in Maui County
and the Big Island had 30-day flow levels in the below normal
range. Little change in average flow levels is expected through
the spring months based on the above-mentioned precipitation
forecast.

Next issuance date...
The next Drought Information Statement will be issued on May 4,
2017 or sooner if necessary in response to significant changes in
conditions.
