...A QUICK RETURN OF SEVERE DROUGHT IN HAWAII...

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.
