.Marianas Synopsis...
A dry forecast continues for the Marianas with most of the
moisture remaining to the south. Seas of 3 to 4 feet were observed
at the buoys.

&&

.Discussion...
Did not make any significant changes to the forecast with the dry
weather pattern firmly in place through the forecast period. With
light wind, we could see some afternoon thunderstorms over Guam
on Thursday, but otherwise, nothing more than isolated showers is
anticipated. Seas remain will remain fairly low through the
period

&&

.Eastern Micronesia...
Weak trade-wind convergence is generating showers and a few
thunderstorms south of Pohnpei and across portions of the Marshalls.
Thicker cirrus clouds are streaming toward the east-northeast from
strong winds aloft. The broad band of convection will generally stay
in the area, but shower coverage is not expected to increase greatly
until the weekend. Showers will increase at Majuro Saturday, at
Kosrae Sunday, and at Pohnpei by Monday.

&&

.Western Micronesia...
All three locations are currently experiencing quiet weather but
showers and thunderstorms persist well southeast of Yap and south of
Chuuk. Convection south of Chuuk will head west the next couple days,
with Chuuk staying dry, but trade-wind convergence in east Micronesia
will bring showers and thunderstorms to the area by the weekend. The
disturbance southeast of Koror and Yap will edge closer to the area
the next few days. Yap will stay just north of most of the activity,
but could see a thunderstorm or two in the next couple of days. Koror
will see isolated showers and thunderstorms developing for the next
few days. Showers will briefly become scattered at times.

The Experimental Drought Assessment of the U.S. Drought Monitor showed that Utirik in the Northern Marshall Islands remained in short term extreme drought (Drought Level 3 of 4) and that Wotje remained in severe drought (Drought Level 2 of 4).

Kwajalein (Ebeye) improved their assessment as they are now in long-term abnormal dry conditions (Drought Level 0 of 4).

Rainfall amounts illustrate the dry conditions as Utirik saw only 1.60 inches of rainfall during the month as opposed to the usual 4.20 inches.

Wotje continues to improve with 8.86 inches compared to the average June rainfall of 5.61 inches. Kwajalein/Ebeye also improved as 10.80 inches fell as opposed to the average of 7.86 inches.
