...SEVERE DROUGHT RETURNS TO MAUI COUNTY...

.SYNOPSIS:

The first month of the May through September dry season produced
below average rainfall in many locations across the state. Leeward
areas were especially dry, resulting in the intensification and
expansion of drought conditions. Severe drought, or the D2
category in the U.S. Drought Monitor map, has already returned to
portions of leeward Maui County. This includes the southwestern
portion of Molokai, the southwestern two-thirds of Kahoolawe, and
the lower leeward slopes of Maui from Maalaea to Kihei. Moderate
drought, or the D1 category, also expanded in Maui County. The D1
conditions now cover the west half of Molokai, the northwestern
portion of Lanai, all of Maui`s central valley, and the lower
leeward Maui slopes from Kaupo to Kepuni, and Kaanapali to
Ukumehame.

Moderate drought also expanded on the Big Island in the Pohakuloa
region and along the lower slopes of the Hawaii Volcanoes National
Park. Elsewhere in the state, moderate drought on Oahu spread
eastward to Diamond Head and westward to Waianae, and developed
along the lower leeward slopes of Kauai from Hanapepe to Waimea.

.SUMMARY OF IMPACTS:
Kauai County
Drought impacts have been in the agriculture sector
where agriculture officials reported deteriorating pastures
between Hanapepe and Waimea. This is consistent with satellite-based
vegetation health data.

Oahu (City and County of Honolulu)
There have not yet been impacts reported. However, ground
observations indicated deteriorating vegetation health along the
lower leeward slopes of Oahu.

Maui County
Reports from the agriculture sector indicated that pasture
conditions have become very poor in the lower leeward sections of
Maui, especially in the region from Maalaea to Kihei. Ranchers in
southwest Molokai reported very poor forage conditions, and
conditions in the rest of west Molokai were deteriorating.

Hawaii County
Ranchers and agriculture officials reported very poor forage conditions
along the lower leeward Kohala slopes, and in the Mana area near
Waimea. Vegetation was also drying out along the Hamakua Coast,
and a brush fire occurred near Paauilo on June 4.

.DROUGHT MITIGATION ACTIONS:

County drought committee meetings are currently in progress
through mid-June to discuss impacts and mitigation actions across
the various communities and sectors.

.LOCAL DROUGHT OUTLOOK:

The Long-Lead Hawaiian Islands Outlook issued on May 20, 2021 by
the NOAA Climate Prediction Center showed probabilities tilted
toward below normal rainfall for the summer and fall 2021.
Probabilities show a slight tilt favoring below normal
temperatures into the middle of fall from the Big Island to Oahu.
Kauai temperatures are expected to be near normal through fall
2021. The next long-lead outlook will be issued by the Climate
Prediction Center on June 17.

With the exception of the Kona slopes of the Big Island, leeward
areas of the state may see increasing drought conditions during
the summer. This is based on the probabilities favoring below
normal rainfall during the summer months. Trade wind rainfall may
be enough to prevent drought development along the windward
slopes. The summer months are part of the wet season on the Kona
slopes, which should be sufficient to mitigate drought development
in this area.

.NEXT ISSUANCE DATE:

The next Drought Information Statement will be issued on July 9,
2021 or sooner if necessary in response to significant changes in
conditions.
