A QUICK RETURN OF SEVERE DROUGHT IN HAWAII

909 AM HST Thu Apr 4 2019


SYNOPSIS...
Following wet conditions in February that removed severe drought,
very dry conditions returned in March and continued into early
April. A pocket of moderate drought, or the D1 category on the
U.S. Drought Monitor map, along the lower leeward slopes of Kauai
has worsened. The area from Waimea to Barking Sands is now
considered to be in severe drought, or the D2 category. Moderate
drought on Kauai has also spread eastward to encompass Hanapepe
and Poipu.

Areas of moderate drought have developed mainly in the leeward
areas of all the remaining counties. On Oahu, this includes most
of the Waianae Range. In Maui County, D1 conditions cover the west
half of Molokai, the leeward slopes of Haleakala and the West Maui
Mountains on the island of Maui, leeward Lanai, and all of
Kahoolawe. On the Big Island, moderate drought covers the slopes
of the South Kohala District from Kawaihae to Waikoloa, and the
Kau District near South Point.

SUMMARY OF IMPACTS...
Kauai
Pasture conditions near Waimea have been deteriorating and were
reported to be in poor condition.

Oahu
Vegetation has been steadily drying over the past month,
especially along the leeward slopes of the Waianae Range.

Maui County
Pastures and vegetation conditions have been deteriorating over
the leeward sections of the county.

Big Island.
Ranchers operating in the lower elevations of the South Kohala
District indicated that pasture conditions were worsening.
Earlier improvements in pasture conditions following February's
rainfall have disappeared.

CLIMATE SUMMARY...
According to the NOAA Climate Prediction Center (CPC), El Nino
conditions are present in the Pacific Ocean. The forecast from
CPC favors a continuation of El Nino through spring of 2019. The
El Nino is expected to remain a weak event based on a consensus of
the main dynamical and statistical models.

PRECIPITATION/TEMPERATURE OUTLOOK...
The Long-Lead Hawaiian Islands Outlook issued on March 21 by the
NOAA Climate Prediction Center shows probabilities favoring below
normal rainfall through the spring due to the ongoing El Nino
event. At this point in the wet season, the drier than normal
conditions are expected to occur mainly along the leeward slopes
with windward areas receiving closer to normal amounts of
rainfall. After a recent period of cooler temperatures,
probabilities favor above normal temperatures across the state
through the summer due to the forecast of above average sea
surface temperatures around the Hawaiian Islands. The next long-
lead outlook will be issued by the Climate Prediction Center on
April 18.

HYDROLOGIC SUMMARY AND OUTLOOK...
Data from the U.S. Geological Survey indicated that most of the
monitored streams across the state had normal to below normal
flow levels. Based on the precipitation outlook, flow levels in
windward streams are expected to remain near normal, while leeward
streams may have reduced flow through spring 2019.

NEXT ISSUANCE DATE...
The next Drought Information Statement will be issued on May 9,
2019 or sooner if necessary in response to significant changes in
conditions.

WET FEBRUARY EASES DROUGHT

1053 AM HST Thu Mar 7 2019


SYNOPSIS...
For users accessing this statement via the web, please note that starting
March 11, the URL for this product will change from
https://www.prh.noaa.gov/hnl/pages/DGT.php to
https://www.weather.gov/hfo/DGT

Wetter than average conditions over the past month have removed
nearly all drought areas across the state. February started with
severe drought, or the D2 category on the U.S. Drought Monitor
map, in the leeward portions of the Big Island and Maui. Moderate
drought, or the D1 category, had spread across most of the Big
Island and also covered the lower leeward slopes of the rest of
the state. By the first week of March, drought had been eliminated
from the Big Island to Oahu. Only a small pocket of moderate
drought remained along the lower leeward slopes of Kauai from
Waimea to Barking Sands.

SUMMARY OF IMPACTS...
Kauai
No drought impacts to report.

Oahu
No drought impacts to report.

Maui County
Pasture and vegetation conditions have been improving due to the above
average rainfall across the county.

Big Island.
Several significant rain episodes helped recovery in areas affected
by drought.

CLIMATE SUMMARY...
According to the NOAA Climate Prediction Center (CPC), El Nino
conditions are present in the Pacific Ocean. The forecast from
CPC favors a continuation of El Nino through spring of 2019. The
El Nino is expected remain a weak event based on a consensus of
the main dynamical and statistical models.

PRECIPITATION/TEMPERATURE OUTLOOK...
The Long-Lead Hawaiian Islands Outlook issued on February 21 by
the NOAA Climate Prediction Center shows probabilities favoring
below normal rainfall through spring due to the ongoing El Nino
event. At this point in the wet season, the drier than normal
conditions are expected to manifest itself mainly along the
leeward slopes with windward areas receiving closer to normal
amounts of rainfall. After a recent period of cooler temperatures,
probabilities favor above normal temperatures across the state
later this spring and into the summer due to the forecast of above
average sea surface temperatures around the Hawaiian Islands. The
next long-lead outlook will be issued by the Climate Prediction
Center on March 21.

HYDROLOGIC SUMMARY AND OUTLOOK...
Data from the U.S. Geological Survey indicated that most of the
monitored streams across the state had near to above normal flow
levels. Based on the precipitation outlook, flow levels in
windward streams are expected to remain near normal, while leeward
streams may have reduced flow through spring 2019.

NEXT ISSUANCE DATE...
Due to the recent improvement in conditions, this will be the
final Drought Information Statement until severe drought returns
to the main Hawaiian Islands.

DROUGHT WORSENS ON THE BIG ISLAND AND LEEWARD MAUI

1054 AM HST Thu Feb 7 2019


SYNOPSIS...
Continued dryness during January, especially over the leeward
sections of the Big Island, resulted in an expansion of severe
drought, or the D2 category on the U.S. Drought Monitor map. The
severe drought area over the South Kohala District of the Big
Island spread farther upslope into the Waikii area. Moderate
drought, or the D1 category, spread eastward to cover all of the
Kau, Puna, South Hilo, and North Hilo Districts, and northward as
far as Ookala in the Hamakua District.

Severe drought was also designated for the lower leeward slope of
Haleakala from Kihei to Wailea. Moderate drought on Maui was also
spreading into the windward areas but was pushed back into the
lower leeward sections of Haleakala and the West Maui Mountains by
wet windward and central valley conditions in late January.

Elsewhere across the state, moderate drought in leeward Kauai
spread southeastward to Koloa, but reduced in size in leeward Oahu
and Molokai.

SUMMARY OF IMPACTS...
Kauai and Oahu.
No significant changes since the last report. Leeward areas of
both islands had deteriorating vegetation conditions. However, no
significant agricultural impacts have yet been reported.

Maui County.
Pastures conditions are poor over the lower leeward slopes of
Haleakala from Kihei to Wailea. Wet conditions during late
January eased drought in Maui's central valley from Wailuku to
Maalaea.

Big Island.
Drought impacts have been increasing over the past
several weeks. The majority of the impacts have been to ranching
operations. These include very poor pasture conditions which have
been resulting in reduced cattle growth. Some ranchers have also
been forced to reduce herd sizes. Several ranchers reported having
to haul water for cattle due to water holes drying up, and have
been providing supplemental feed, which increases operating
costs. An aquaculture operation in upper Hilo reported having to
provide aeration for their fish due to inadequate surface water
and spring flows.

CLIMATE SUMMARY...
According to the NOAA Climate Prediction Center (CPC), ENSO-
neutral conditions are still present in the Pacific Ocean. The
forecast from CPC continues to favor a transition to an El Nino
state in early 2019. The El Nino is forecast to be a weak event by
a consensus of the main dynamical and statistical models.

PRECIPITATION/TEMPERATURE OUTLOOK...
The Long-Lead Hawaiian Islands Outlook issued on January 17 by the NOAA
Climate Prediction Center shows probabilities favoring below normal
rainfall into the spring months as a result of the developing El
Nino event. Probabilities favor above normal temperatures across
the entire state into the summer due to the forecast of above
average sea surface temperatures around the Hawaiian Islands. The
next long-lead outlook will be issued by the Climate Prediction
Center on February 21.

HYDROLOGIC SUMMARY AND OUTLOOK...
Data from the U.S. Geological Survey indicated that most of the
monitored streams across the state had near to below normal flow
levels. Based on the precipitation outlook, flow levels are expected
to remain near to below normal through spring 2019.

NEXT ISSUANCE DATE...
The next Drought Information Statement will be issued on March 7,
2019 or sooner if necessary in response to significant changes in
conditions.

SEVERE DROUGHT RETURNS TO THE BIG ISLAND

844 AM HST Thu Jan 17 2019


SYNOPSIS...
Below average rainfall combined with periods of strong winds in
December have produced very dry conditions over some of the lower
leeward slopes of the Big Island. Pastures in portions of the
South Kohala District from Kawaihae to Waikoloa have deteriorated
enough to be considered in severe drought, or the D2 category on
the U.S. Drought Monitor Map. Most of the remaining leeward areas
are considered to be under moderate drought, or the D1 category.
The only leeward Big Island area not yet under drought is along
the slopes of the South Kona District from Holualoa to Kealakekua.

The lower leeward slopes of Maui, Oahu, and Kauai, and all of
Lanai and Kahoolawe have also been under dry conditions and are
considered to be in moderate drought.

In the short term, a series of cold fronts reaching the state over
the next several days may temporarily delay the expansion of
drought. However, drought conditions are expected to expand and
worsen across the state by the end of the wet season as El Nino-
related dryness persists.

SUMMARY OF IMPACTS...

Kauai and Oahu
Leeward areas of both islands had deteriorating general vegetation
conditions. However, no significant agricultural impacts have yet
been reported.

Maui County
Vegetation has been deteriorating over the past several weeks.
Pastures over the lower leeward slopes of Haleakala were drying
and brush fire risk has been increasing, highlighted by the early
January fire near Wailea.

Big Island.
Pastures were reported to be in poor condition over the lower
elevations of the South Kohala District. The worst conditions
were in the area from Kawaihae to Waikoloa Village. Dry vegetation
conditions were also present in the Kau District, especially
south of Pahala.

CLIMATE SUMMARY...
According to the NOAA Climate Prediction Center, ENSO-neutral
conditions are present in the Pacific Ocean but probabilities
continue to favor a transition to an El Nino state in early 2019.
The El Nino is forecast to be a weak event by a consensus of the
main dynamical and statistical climate models.

PRECIPITATION/TEMPERATURE OUTLOOK...
The Long-Lead Hawaiian Islands Outlook issued on January 17 by the
NOAA Climate Prediction Center shows probabilities favoring below
normal rainfall into the spring months as a result of the
developing El Nino event. Probabilities favor above normal
temperatures across the entire state into the summer due to the
forecast of above average sea surface temperatures around the
Hawaiian Islands. The next long-lead outlook will be issued by the
Climate Prediction Center on February 21.

HYDROLOGIC SUMMARY AND OUTLOOK...
Data from the U.S. Geological Survey indicated that most of the
monitored streams across the state had near to below normal flow
levels. Based on the precipitation outlook, flow levels are
expected to remain near to below normal through spring 2019.

NEXT ISSUANCE DATE...
The next Drought Information Statement will be issued on February
7, 2019 or sooner if necessary in response to significant changes
in conditions.
