Drought Information Statement
National Weather Service Honolulu HI
959 AM HST Thu Oct 10 2019

...WET SEASON BEGINS WITH POCKETS OF EXTREME DROUGHT OVER
PORTIONS OF MAUI AND THE BIG ISLAND...

SYNOPSIS...

Upper level disturbances combined with above normal low level
moisture helped produce higher than average rainfall over many
areas of the state. However, most of this rainfall missed the
worst drought areas. These include localized areas of extreme
drought, or the D3 category on the U.S. Drought Monitor map, over
the northern and southern tips of the Big Island, and along the
lower leeward slopes of Haleakala on Maui. Severe drought, or the
D2 category, also existed along the lower Hamakua slopes on the
Big Island, leeward Maui, the west half of Molokai, southwest
Lanai, and all of Kahoolawe.

On Oahu, an increase in rainfall helped reduce the coverage of
moderate drought, or the D1 category, along the lower leeward
slopes of the island. At present, D1 conditions only remained over
lower west Oahu from Ewa to Waianae.

SUMMARY OF IMPACTS...

Kauai
There are no drought areas in Kauai County.

Oahu
Satellite based vegetation health data indicated poor conditions from
Ewa to Waianae. Conditions from Ewa to Hawaii Kai have improved over
the past month.

Maui County
On Maui, pasture conditions remained very poor along most of the
lower leeward slopes of Haleakala from Kihei to Kaupo. Serious
brushfires continue to cause problems, most recently over the area
from Maalaea to Ukumehame, which was under severe drought. Occasional
afternoon heavy rainfall along a corridor from Ulupalakua to Makena
helped improved conditions, but satellite based vegetation health
data corroborated by some ground reports indicated that pasture
conditions remained very poor from Kepuni to Kaupo, and from Wailea
to Maalaea. On Molokai, satellite-based vegetation health data
indicated poor conditions on the west half of the island. Vegetation
conditions were also poor over southwest Lanai. While this area
is normally dry, the satellite data, confirmed by visual inspection,
showed that conditions appeared to be worse than normal.

Big Island.
Reports from ginger and sweet potato producers along the Hamakua
Coast indicated that crop growth was being affected by the dry
conditions. Insect damage has also increased. Ranchers operating in
a localized area near South Point reported very poor pasture conditions
despite much better conditions not too far away. These conditions
were also detected by the satellite based data and corroborated by
photos. In addition to these reports, the satellite-based data indicated
that the worst vegetation conditions on the island were along the
lower leeward slopes of the Kohala Mountains south of Hawi and near
Upolu Airport.

DROUGHT MITIGATION ACTIONS
A Stage 1 Water Shortage declaration, issued by the Maui County
Department of Water Supply, remained in effect for Upcountry Maui.
The declaration requests residents to voluntarily reduce water
consumption by 10 percent.

Assistance programs from the U.S. Department of Agriculture`s
Farm Service Agency have been implemented for farmers and ranchers
in Maui County and the Big Island due to the ongoing drought conditions.

LOCAL DROUGHT OUTLOOK
The Long-Lead Hawaiian Islands Outlook issued on September 19 by
the NOAA Climate Prediction Center shows probabilities favoring
above normal rainfall across the state through the remainder of
2019. Probabilities also favor above normal temperatures across
the state through the rest of 2019 due to the forecast of
persistent above average sea surface temperatures around the
Hawaiian Islands. The next long-lead outlook will be issued by the
Climate Prediction Center on September 19.

For the rest of 2019, drought conditions should ease with the onset
of the Hawaiian Islands wet season along with the forecast for above
normal rainfall. The wet season weather systems provide a higher
likelihood of rainfall getting into the leeward areas which currently
have drought.

NEXT ISSUANCE DATE...
The next Drought Information Statement will be issued on November
8, 2019 or sooner if necessary in response to significant changes
in conditions.
