...DROUGHT CONTINUES FOR KAPINGAMARANGI IN FAR SOUTHERN POHNPEI STATE...

.SYNOPSIS:
Although sea surface temperatures in the tropical Pacific have warmed
the past few weeks, La Nina still persists. A weak La Nina to neutral
ENSO scenario is still expected late in the year (Oct-Dec), with a
slight nod to La Nina as the most likely scenario.

Inadequate rainfall (<8"/month) is expected to continue for
Kapingamarangi due to the overall La Nina base state. See the drought
outlook section for more details on rainfall expectations.

Preliminary rainfall (inches) for select islands across Pohnpei
State. % of monthly normal rainfall based on 1991-2020 data.

Water levels for both private and public water tanks are roughly 30%
of capacity. Vegetation is turning yellow.

.DROUGHT MITIGATION ACTIONS:
A ship recently delivered water supplies to the island. Eight 1,500
gallon water tanks were also shipped to Kapinga recently. These water
tanks will bolster water resources once they are installed.

.LOCAL DROUGHT OUTLOOK:
1-3 inches of rainfall is expected through the first week of July.
Rainfall is still expected to be inadequate (< than 8"/month) to
meet most water needs the next several months. This is supported by
seasonal model guidance and the ongoing La Nina climate pattern.

.NEXT ISSUANCE DATE:
The next Drought Information Statement will be issued Friday, July 8,
2022 or sooner if necessary.
