...DROUGHT EASES A BIT FOR KAPINGAMARANGI...

.SYNOPSIS:
Trade winds have strengthened across the Pacific recently as the La
Nina base state reestablishes. A weak La Nina to "cool side of neutral"
ENSO scenario is expected later this year (Oct-Dec). Overall model
consensus gives a slight nod to La Nina as the most likely scenario
late this year.

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.

Public and private water tanks are slightly over 50%. This is an
improvement from mid June. Vegetation is still yellow.

.DROUGHT MITIGATION ACTIONS:
Residents continue to conserve water. 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:
2-4 inches of rainfall is expected through the end of the month.
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 22,
2022 or sooner if necessary.
