Drought Information Statement

...WET SEPTEMBER ELIMINATES SEVERE DROUGHT...

SYNOPSIS...

Above average rainfall during September, which included the impact
of Tropical Storm Olivia, brought continued relief to the
remaining leeward areas still affected by drought conditions.
Thus, severe drought, or the D2 category on the U.S. Drought
Monitor Map, has eased to moderate drought, or the D1 category
over the lower leeward slopes of west Maui and the South Kohala
and North Kona Districts of the Big Island. It is expected that
even these remaining D1 areas will be removed soon as vegetation
continues to recover.

SUMMARY OF IMPACTS...

Kauai and Oahu
There are no drought impacts to report.

Maui County
Vegetation has been improving over the lower leeward sections of
the West Maui Mountains, especially after the follow-up rainfall
in late September. It is expected that drought conditions will
soon be completely eliminated.

Big Island
Pastures and general vegetation over the lower elevations of the
South Kohala and North Kona Districts have been improving as a
result of September rainfall. It is expected that drought
conditions will soon be completely eliminated.

CLIMATE SUMMARY...
According to the NOAA Climate Prediction Center, ENSO-neutral conditions
are present in the Pacific Ocean but probabilities favor a transition
to El Nino conditions by the end of 2018.

PRECIPITATION/TEMPERATURE OUTLOOK...
The Long-Lead Hawaiian Islands Outlook issued on September 20 by
the NOAA Climate Prediction Center shows probabilities favoring
below normal rainfall for the upcoming winter and spring months as
a result of the developing El Nino event. Probabilities favor
above normal temperatures across the entire state into early 2019
due to the forecasted persistence of above average sea surface
temperatures around the Hawaiian Islands. The next long-lead
outlook will be issued by the Climate Prediction Center on October
18.

HYDROLOGIC SUMMARY AND OUTLOOK...
Data from the U.S. Geological Survey indicated that most of the monitored
streams across the state had flow levels in the above normal to
high flow percentile classes. Based on the precipitation outlook,
flow levels are expected to decrease by late 2018.

NEXT ISSUANCE DATE...
This will be the final Drought Information Statement until severe
drought returns to the main Hawaiian Islands.
